text: We prove an adiabatic theorem for the Landau–Pekar equations. This allows
us to derive new results on the accuracy of their use as effective equations for
the time evolution generated by the Fröhlich Hamiltonian with large coupling constant
α. In particular, we show that the time evolution of Pekar product states with
coherent phonon field and the electron being trapped by the phonons is well approximated
by the Landau–Pekar equations until times short compared to α2.

text: Methods inspired from machine learning have recently attracted great interest
in the computational study of quantum many-particle systems. So far, however,
it has proven challenging to deal with microscopic models in which the total number
of particles is not conserved. To address this issue, we propose a new variant
of neural network states, which we term neural coherent states. Taking the Fröhlich
impurity model as a case study, we show that neural coherent states can learn
the ground state of non-additive systems very well. In particular, we observe
substantial improvement over the standard coherent state estimates in the most
challenging intermediate coupling regime. Our approach is generic and does not
assume specific details of the system, suggesting wide applications.

text: Given the abundance of applications of ranking in recent years, addressing
fairness concerns around automated ranking systems becomes necessary for increasing
the trust among end-users. Previous work on fair ranking has mostly focused on
application-specific fairness notions, often tailored to online advertising, and
it rarely considers learning as part of the process. In this work, we show how
to transfer numerous fairness notions from binary classification to a learning
to rank setting. Our formalism allows us to design methods for incorporating fairness
objectives with provable generalization guarantees. An extensive experimental
evaluation shows that our method can improve ranking fairness substantially with
no or only little loss of model quality.

text: Ligands are a fundamental part of nanocrystals. They control and direct nanocrystal
syntheses and provide colloidal stability. Bound ligands also affect the nanocrystals’
chemical reactivity and electronic structure. Surface chemistry is thus crucial
to understand nanocrystal properties and functionality. Here, we investigate the
synthesis of metal oxide nanocrystals (CeO2-x, ZnO, and NiO) from metal nitrate
precursors, in the presence of oleylamine ligands. Surprisingly, the nanocrystals
are capped exclusively with a fatty acid instead of oleylamine. Analysis of the
reaction mixtures with nuclear magnetic resonance spectroscopy revealed several
reaction byproducts and intermediates that are common to the decomposition of
Ce, Zn, Ni, and Zr nitrate precursors. Our evidence supports the oxidation of
alkylamine and formation of a carboxylic acid, thus unraveling this counterintuitive
surface chemistry.

text: Thermoelectric materials are engines that convert heat into an electrical
current. Intuitively, the efficiency of this process depends on how many electrons
(charge carriers) can move and how easily they do so, how much energy those moving
electrons transport, and how easily the temperature gradient is maintained. In
terms of material properties, an excellent thermoelectric material requires a
high electrical conductivity σ, a high Seebeck coefficient S (a measure of the
induced thermoelectric voltage as a function of temperature gradient), and a low
thermal conductivity κ. The challenge is that these three properties are strongly
interrelated in a conflicting manner (1). On page 722 of this issue, Roychowdhury
et al. (2) have found a way to partially break these ties in silver antimony telluride
(AgSbTe2) with the addition of cadmium (Cd) cations, which increase the ordering
in this inherently disordered thermoelectric material.

text: Basket weaving is a traditional craft for creating curved surfaces as an interwoven
array of thin, flexible, and initially straight ribbons. The three-dimensional
shape of a woven structure emerges through a complex interplay of the elastic
bending behavior of the ribbons and the contact forces at their crossings. Curvature
can be injected by carefully placing topological singularities in the otherwise
regular weaving pattern. However, shape control through topology is highly non-trivial
and inherently discrete, which severely limits the range of attainable woven geometries.
Here, we demonstrate how to construct arbitrary smooth free-form surface geometries
by weaving carefully optimized curved ribbons. We present an optimization-based
approach to solving the inverse design problem for such woven structures. Our
algorithm computes the ribbons' planar geometry such that their interwoven assembly
closely approximates a given target design surface in equilibrium. We systematically
validate our approach through a series of physical prototypes to show a broad
range of new woven geometries that is not achievable by existing methods. We anticipate
our computational approach to significantly enhance the capabilities for the design
of new woven structures. Facilitated by modern digital fabrication technology,
we see potential applications in material science, bio- and mechanical engineering,
art, design, and architecture.

text: Inspired by motion patterns of some commercially available mobile robots,
we investigate the power of robots that move forward in straight lines until colliding
with an environment boundary, at which point they can rotate in place and move
forward again; we visualize this as the robot “bouncing” off boundaries. We define
bounce rules governing how the robot should reorient after reaching a boundary,
such as reorienting relative to its heading prior to collision, or relative to
the normal of the boundary. We then generate plans as sequences of rules, using
the bounce visibility graph generated from a polygonal environment definition,
while assuming we have unavoidable non-determinism in our actuation. Our planner
can be queried to determine the feasibility of tasks such as reaching goal sets
and patrolling (repeatedly visiting a sequence of goals). If the task is found
feasible, the planner provides a sequence of non-deterministic interaction rules,
which also provide information on how precisely the robot must execute the plan
to succeed. We also show how to compute stable cyclic trajectories and use these
to limit uncertainty in the robot’s position.

text: "Given the central role that C continues to play in systems software, and
the difficulty of writing safe and correct C code, it remains a grand challenge
to develop effective formal methods for verifying C programs. In this paper, we
propose a new approach to this problem: a type system we call RefinedC, which
combines ownership types (for modular reasoning about shared state and concurrency)
with refinement types (for encoding precise invariants on C data types and Hoare-style
specifications for C functions).\r\nRefinedC is both automated (requiring minimal
user intervention) and foundational (producing a proof of program correctness
in Coq), while at the same time handling a range of low-level programming idioms
such as pointer arithmetic. In particular, following the approach of RustBelt,
the soundness of the RefinedC type system is justified semantically by interpretation
into the Coq-based Iris framework for higher-order concurrent separation logic.
However, the typing rules of RefinedC are also designed to be encodable in a new
“separation logic programming” language we call Lithium. By restricting to a carefully
chosen (yet expressive) fragment of separation logic, Lithium supports predictable,
automatic, goal-directed proof search without backtracking. We demonstrate the
effectiveness of RefinedC on a range of representative examples of C code."

text: "This paper presents the ESA Voyage 2050 White Paper for a concept of TeraHertz
Exploration and Zooming-in for Astrophysics (THEZA). It addresses the science
case and some implementation issues of a space-borne radio interferometric system
for ultra-sharp imaging of celestial radio sources at the level of angular resolution
down to (sub-) microarcseconds. THEZA focuses at millimetre and sub-millimetre
wavelengths (frequencies above \r\n300 GHz), but allows for science operations
at longer wavelengths too. The THEZA concept science rationale is focused on the
physics of spacetime in the vicinity of supermassive black holes as the leading
science driver. The main aim of the concept is to facilitate a major leap by providing
researchers with orders of magnitude improvements in the resolution and dynamic
range in direct imaging studies of the most exotic objects in the Universe, black
holes. The concept will open up a sizeable range of hitherto unreachable parameters
of observational astrophysics. It unifies two major lines of development of space-borne
radio astronomy of the past decades: Space VLBI (Very Long Baseline Interferometry)
and mm- and sub-mm astrophysical studies with “single dish” instruments. It also
builds upon the recent success of the Earth-based Event Horizon Telescope (EHT)
– the first-ever direct image of a shadow of the super-massive black hole in the
centre of the galaxy M87. As an amalgam of these three major areas of modern observational
astrophysics, THEZA aims at facilitating a breakthrough in high-resolution high
image quality studies in the millimetre and sub-millimetre domain of the electromagnetic
spectrum."

text: The recently discovered gravitational wave sources GW190521 and GW190814 have
shown evidence of BH mergers with masses and spins outside of the range expected
from isolated stellar evolution. These merging objects could have undergone previous
mergers. Such hierarchical mergers are predicted to be frequent in active galactic
nuclei (AGNs) disks, where binaries form and evolve efficiently by dynamical interactions
and gaseous dissipation. Here we compare the properties of these observed events
to the theoretical models of mergers in AGN disks, which are obtained by performing
one-dimensional N-body simulations combined with semi-analytical prescriptions.
The high BH masses in GW190521 are consistent with mergers of high-generation
(high-g) BHs where the initial progenitor stars had high metallicity, 2g BHs if
the original progenitors were metal-poor, or 1g BHs that had gained mass via super-Eddington
accretion. Other measured properties related to spin parameters in GW190521 are
also consistent with mergers in AGN disks. Furthermore, mergers in the lower mass
gap or those with low mass ratio as found in GW190814 and GW190412 are also reproduced
by mergers of 2g–1g or 1g–1g objects with significant accretion in AGN disks.
Finally, due to gas accretion, the massive neutron star merger reported in GW190425
can be produced in an AGN disk.

text: 'The disks of active galactic nuclei (AGNs) have emerged as a rich environment
for the evolution of stars and their compact remnants. The very dense medium favors
rapid accretion, while torques and migration traps enhance binary formation and
mergers. Both long and short gamma-ray bursts are hence expected. We show that
AGN disks constitute an ideal environment for another interesting phenomenon:
the accretion-induced collapse (AIC) of neutron stars (NSs) to black holes (BHs).
Rapid accretion in the dense disks can cause NSs to grow to the point of exceeding
the maximum mass allowed by their equation of state. General relativistic magnetohydrodynamical
simulations have shown that electromagnetic signatures are expected if the NS
is surrounded by a minidisk prior to collapse, which then rapidly accretes onto
the BH, and/or if the NS is highly magnetized, from reconnection of the magnetosphere
during collapse. Here we compute the rates of AICs and their locations within
the disks for both isolated NSs and for (initially stable) NSs formed from NS-NS
mergers. We find that the global AIC rates are ∼0.07–20 Gpc−3 yr−1, and we discuss
their observable prospects and signatures as they emerge from the dense disk environments.'

text: We study the effect of baryonic processes on weak lensing (WL) observables
with a suite of mock WL maps, the κTNG, based on the cosmological hydrodynamic
simulations IllustrisTNG. We quantify the baryonic effects on the WL angular power
spectrum, one-point probability distribution function (PDF), and number counts
of peaks and minima. We also show the redshift evolution of the effects, which
is a key to distinguish the effect of baryons from fundamental physics such as
dark energy, dark matter, and massive neutrinos. We find that baryonic processes
reduce the small-scale power, suppress the tails of the PDF, peak and minimum
counts, and change the total number of peaks and minima. We compare our results
to existing semi-analytical models and hydrodynamic simulations, and discuss the
source of discrepancies. The κTNG suite includes 10 000 realizations of $5 \times
5 \, \mathrm{deg}^2$ maps for 40 source redshifts up to zs = 2.6, well covering
the range of interest for existing and upcoming WL surveys. We also produce the
κTNG-Dark suite of maps, generated based on the corresponding dark matter-only
IllustrisTNG simulations. Our mock maps are not only suitable for developing analytical
models that incorporate the effect of baryons, but also particularly useful for
studies that rely on mass maps, such as non-Gaussian statistics and machine learning
with convolutional neural networks. The suite of mock maps is publicly available
at Columbia Lensing (http://columbialensing.org).

text: Since the very beginning of astronomy the location of objects on the sky has
been a fundamental observational quantity that has been taken for granted. While
precise two dimensional positional information is easy to obtain for observations
in the electromagnetic spectrum, the positional accuracy of current and near future
gravitational wave detectors is limited to between tens and hundreds of square
degrees, which makes it extremely challenging to identify the host galaxies of
gravitational wave events or to detect any electromagnetic counterparts. Gravitational
wave observations provide information on source properties that is complementary
to the information in any associated electromagnetic emission. Observing systems
with multiple messengers thus has scientific potential much greater than the sum
of its parts. A gravitational wave detector with higher angular resolution would
significantly increase the prospects for finding the hosts of gravitational wave
sources and triggering a multi-messenger follow-up campaign. An observatory with
arcminute precision or better could be realised within the Voyage 2050 programme
by creating a large baseline interferometer array in space and would have transformative
scientific potential. Precise positional information of standard sirens would
enable precision measurements of cosmological parameters and offer new insights
on structure formation; a high angular resolution gravitational wave observatory
would allow the detection of a stochastic background and resolution of the anisotropies
within it; it would also allow the study of accretion processes around black holes;
and it would have tremendous potential for tests of modified gravity and the discovery
of physics beyond the Standard Model.

text: We propose a space-based interferometer surveying the gravitational wave (GW)
sky in the milli-Hz to μ-Hz frequency range. By the 2040s, the μ-Hz frequency
band, bracketed in between the Laser Interferometer Space Antenna (LISA) and pulsar
timing arrays, will constitute the largest gap in the coverage of the astrophysically
relevant GW spectrum. Yet many outstanding questions related to astrophysics and
cosmology are best answered by GW observations in this band. We show that a μ-Hz
GW detector will be a truly overarching observatory for the scientific community
at large, greatly extending the potential of LISA. Conceived to detect massive
black hole binaries from their early inspiral with high signal-to-noise ratio,
and low-frequency stellar binaries in the Galaxy, this instrument will be a cornerstone
for multimessenger astronomy from the solar neighbourhood to the high-redshift
Universe.

text: As weak lensing surveys are becoming deeper and cover larger areas, information
will be available on small angular scales down to the arcmin level. To extract
this extra information, accurate modelling of baryonic effects is necessary. In
this work, we adopt a baryonic correction model, which includes gas both bound
inside and ejected from dark matter (DM) haloes, a central galaxy, and changes
in the DM profile induced by baryons. We use this model to incorporate baryons
into a large suite of DM-only N-body simulations, covering a grid of 75 cosmologies
in the Ωm–σ8 parameter space. We investigate how baryons affect Gaussian and non-Gaussian
weak lensing statistics and the cosmological parameter inferences from these statistics.
Our results show that marginalizing over baryonic parameters degrades the constraints
in Ωm–σ8 space by a factor of 2–5 compared to those with baryonic parameters fixed.
We also find that combining the lensing power spectrum and peak counts can break
the degeneracy between cosmological and baryonic parameters and mitigate the impact
of the uncertainty in baryonic physics.

text: 'The Legacy Survey of Space and Time (LSST) by the Vera C. Rubin Observatory
is expected to discover tens of millions of quasars. A significant fraction of
these could be powered by coalescing massive black hole (MBH) binaries, since
many quasars are believed to be triggered by mergers. We show that under plausible
assumptions about the luminosity functions, lifetimes, and binary fractions of
quasars, we expect the full LSST quasar catalogue to contain between 20 and 100
million compact MBH binaries with masses M = 105–9M⊙, redshifts z = 0–6, and orbital
periods P = 1–70 d. Their light-curves are expected to be distinctly periodic,
which can be confidently distinguished from stochastic red-noise variability,
because LSST will cover dozens, or even hundreds of cycles. A very small subset
of 10–150 ultracompact (P ≲ 1 d) binary quasars among these will, over ∼5–15 yr,
evolve into the mHz gravitational-wave frequency band and can be detected by LISA.
They can therefore be regarded as ‘LISA verification binaries’, analogous to short-period
Galactic compact-object binaries. The practical question is how to find these
handful of ‘needles in the haystack’ among the large number of quasars: this will
likely require a tailored co-adding analysis optimized for this purpose.'

text: "If primordial black holes (PBHs) seeded the supermassive black holes (SMBHs)
at the centers of high-redshift quasars, then the gas surrounding these black
holes may reveal nucleosynthetic clues to their primordial origins. We present
predictions of altered primordial abundances around PBHs massive enough to seed
SMBHs at \U0001D467≈6–7.5. We find that if PBHs with initial masses of ∼105 M⊙
are responsible for such SMBHs, they may produce primordial deuterium and Helium
fractions enhanced by ≥10%, and lithium abundance depleted by ≥10%, at distances
of up to ≈ a comoving kiloparsec away from the black hole after decoupling. We
estimate that ∼108 M⊙ of gas is enhanced (or depleted) by at least one percent.
Evidence of these modified primordial deuterium, helium, and lithium abundances
could still be present if this circum-PBH gas remains unaccreted by the SMBH and
in or near the host galaxies of high-redshift quasars. Measuring the abundance
anomalies will be challenging, but could offer a novel way to reveal the primordial
origin of such SMBH seeds."

text: The astrophysical origin of gravitational wave transients is a timely open
question in the wake of discoveries by the Laser Interferometer Gravitational-Wave
Observatory (LIGO)/Virgo. In active galactic nuclei (AGNs), binaries form and
evolve efficiently by interaction with a dense population of stars and the gaseous
AGN disk. Previous studies have shown that stellar-mass black hole (BH) mergers
in such environments can explain the merger rate and the number of suspected hierarchical
mergers observed by LIGO/Virgo. The binary eccentricity distribution can provide
further information to distinguish between astrophysical models. Here we derive
the eccentricity distribution of BH mergers in AGN disks. We find that eccentricity
is mainly due to binary–single (BS) interactions, which lead to most BH mergers
in AGN disks having a significant eccentricity at 0.01 Hz, detectable by the Laser
Interferometer Space Antenna. If BS interactions occur in isotropic-3D directions,
then 8%–30% of the mergers in AGN disks will have eccentricities at 10 Hz above
e10 Hz ≳ 0.03, detectable by LIGO/Virgo/Kamioka Gravitational Wave Detector, while
5%–17% of mergers have e10 Hz ≥ 0.3. On the other hand, if BS interactions are
confined to the AGN–disk plane due to torques from the disk, with 1–20 intermediate
binary states during each interaction, or if BHs can migrate to ≲ 10−3 pc from
the central supermassive BH, then 10%–70% of the mergers will be highly eccentric
(e10 Hz ≥ 0.3), consistent with the possible high eccentricity in GW190521.

text: Recent gravitational wave (GW) observations by LIGO/Virgo show evidence for
hierarchical mergers, where the merging BHs are the remnants of previous BH merger
events. These events may carry important clues about the astrophysical host environments
of the GW sources. In this paper, we present the distributions of the effective
spin parameter (χeff), the precession spin parameter (χp), and the chirp mass
(mchirp) expected in hierarchical mergers. Under a wide range of assumptions,
hierarchical mergers produce (i) a monotonic increase of the average of the typical
total spin for merging binaries, which we characterize with χ¯typ≡(χ2eff+χ2p)1/2¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯,
up to roughly the maximum mchirp among first-generation (1g) BHs, and (ii) a plateau
at χ¯typ∼0.6 at higher mchirp. We suggest that the maximum mass and typical spin
magnitudes for 1g BHs can be estimated from χ¯typ as a function of mchirp. The
GW data observed in LIGO/Virgo O1--O3a prefers an increase in χ¯typ at low mchirp,
which is consistent with the growth of the BH spin magnitude by hierarchical mergers,
at ∼2σ confidence. A Bayesian analysis suggests that 1g BHs have the maximum mass
of ∼15--30M⊙ if the majority of mergers are of high-generation BHs (not among
1g-1g BHs), which is consistent with mergers in active galactic nucleus disks
and/or nuclear star clusters, while if mergers mainly originate from globular
clusters, 1g BHs are favored to have non-zero spin magnitudes of ∼0.3. We also
forecast that signatures for hierarchical mergers in the χ¯typ distribution can
be confidently recovered once the number of GW events increases to ≳O(100).

text: Variable active galactic nuclei showing periodic light curves have been proposed
as massive black hole binary (MBHB) candidates. In such scenarios, the periodicity
can be due to relativistic Doppler-boosting of the emitted light. This hypothesis
can be tested through the timing of scattered polarized light. Following the results
of polarization studies in type I nuclei and of dynamical studies of MBHBs with
circumbinary discs, we assume a coplanar equatorial scattering ring, whose elements
contribute differently to the total polarized flux, due to different scattering
angles, levels of Doppler boost, and line-of-sight time delays. We find that in
the presence of an MBHB, both the degree of polarization and the polarization
position angle have periodic modulations. The polarization angle oscillates around
the semiminor axis of the projected MBHB orbital ellipse, with a frequency equal
either to the binary’s orbital frequency (for large scattering screen radii),
or twice this value (for smaller scattering structures). These distinctive features
can be used to probe the nature of periodic MBHB candidates and to compile catalogues
of the most promising sub-pc MBHBs. The identification of such polarization features
in gravitational-wave (GW) detected MBHBs would enormously increase the amount
of physical information about the sources, allowing the measurement of the individual
masses of the binary components, and the orientation of the line of nodes on the
sky, even for monochromatic GW signals.
