text: The impulsive limit (the “sudden approximation”) has been widely employed
to describe the interaction between molecules and short, far-off-resonant laser
pulses. This approximation assumes that the timescale of the laser-molecule interaction
is significantly shorter than the internal rotational period of the molecule,
resulting in the rotational motion being instantaneously “frozen” during the interaction.
This simplified description of the laser-molecule interaction is incorporated
in various theoretical models predicting rotational dynamics of molecules driven
by short laser pulses. In this theoretical work, we develop an effective theory
for ultrashort laser pulses by examining the full time-evolution operator and
solving the time-dependent Schrödinger equation at the operator level. Our findings
reveal a critical angular momentum, lcrit, at which the impulsive limit breaks
down. In other words, the validity of the sudden approximation depends not only
on the pulse duration but also on its intensity, since the latter determines how
many angular momentum states are populated. We explore both ultrashort multicycle
(Gaussian) pulses and the somewhat less studied half-cycle pulses, which produce
distinct effective potentials. We discuss the limitations of the impulsive limit
and propose a method that rescales the effective matrix elements, enabling an
improved and more accurate description of laser-molecule interactions.

text: Graphical games are a useful framework for modeling the interactions of (selfish)
agents who are connected via an underlying topology and whose behaviors influence
each other. They have wide applications ranging from computer science to economics
and biology. Yet, even though an agent’s payoff only depends on the actions of
their direct neighbors in graphical games, computing the Nash equilibria and making
statements about the convergence time of "natural" local dynamics in particular
can be highly challenging. In this work, we present a novel approach for classifying
complexity of Nash equilibria in graphical games by establishing a connection
to local graph algorithms, a subfield of distributed computing. In particular,
we make the observation that the equilibria of graphical games are equivalent
to locally verifiable labelings (LVL) in graphs; vertex labelings which are verifiable
with constant-round local algorithms. This connection allows us to derive novel
lower bounds on the convergence time to equilibrium of best-response dynamics
in graphical games. Since we establish that distributed convergence can sometimes
be provably slow, we also introduce and give bounds on an intuitive notion of
"time-constrained" inefficiency of best responses. We exemplify how our results
can be used in the implementation of mechanisms that ensure convergence of best
responses to a Nash equilibrium. Our results thus also give insight into the convergence
of strategy-proof algorithms for graphical games, which is still not well understood.

text: Traditional blockchains grant the miner of a block full control not only over
which transactions but also their order. This constitutes a major flaw discovered
with the introduction of decentralized finance and allows miners to perform MEV
attacks. In this paper, we address the issue of sandwich attacks by providing
a construction that takes as input a blockchain protocol and outputs a new blockchain
protocol with the same security but in which sandwich attacks are not profitable.
Furthermore, our protocol is fully decentralized with no trusted third parties
or heavy cryptography primitives and carries a linear increase in latency and
minimum computation overhead.

text: "Oblivious routing is a well-studied paradigm that uses static precomputed
routing tables for selecting routing paths within a network. Existing oblivious
routing schemes with polylogarithmic competitive ratio for general networks are
tree-based, in the sense that routing is performed according to a convex combination
of trees. However, this restriction to trees leads to a construction that has
time quadratic in the size of the network and does not parallelize well. \r\nIn
this paper we study oblivious routing schemes based on electrical routing. In
particular, we show that general networks with n vertices and m edges admit a
routing scheme that has competitive ratio O(log² n) and consists of a convex combination
of only O(√m) electrical routings. This immediately leads to an improved construction
algorithm with time Õ(m^{3/2}) that can also be implemented in parallel with
Õ(√m) depth."

text: We consider quadratic forms of deterministic matrices A evaluated at the random
eigenvectors of a large N×N GOE or GUE matrix, or equivalently evaluated at the
columns of a Haar-orthogonal or Haar-unitary random matrix. We prove that, as
long as the deterministic matrix has rank much smaller than √N, the distributions
of the extrema of these quadratic forms are asymptotically the same as if the
eigenvectors were independent Gaussians. This reduces the problem to Gaussian
computations, which we carry out in several cases to illustrate our result, finding
Gumbel or Weibull limiting distributions depending on the signature of A. Our
result also naturally applies to the eigenvectors of any invariant ensemble.

text: The GNOM (GN) Guanine nucleotide Exchange Factor for ARF small GTPases (ARF-GEF)
is among the best studied trafficking regulators in plants, playing crucial and
unique developmental roles in patterning and polarity. The current models place
GN at the Golgi apparatus (GA), where it mediates secretion/recycling, and at
the plasma membrane (PM) presumably contributing to clathrin-mediated endocytosis
(CME). The mechanistic basis of the developmental function of GN, distinct from
the other ARF-GEFs including its closest homologue GNOM-LIKE1 (GNL1), remains
elusive. Insights from this study largely extend the current notions of GN function.
We show that GN, but not GNL1, localizes to the cell periphery at long-lived structures
distinct from clathrin-coated pits, while CME and secretion proceed normally in
gn knockouts. The functional GN mutant variant GNfewerroots,
absent from the GA, suggests that the cell periphery is the major site of GN action
responsible for its developmental function. Following inhibition by Brefeldin
A, GN, but not GNL1, relocates to the PM likely on exocytic vesicles, suggesting
selective molecular associations en route to the cell periphery. A study of GN-GNL1
chimeric ARF-GEFs indicates that all GN domains contribute to the specific GN
function in a partially redundant manner. Together, this study offers significant
steps toward the elucidation of the mechanism underlying unique cellular and development
functions of GNOM.

text: Coupling of orbital motion to a spin degree of freedom gives rise to various
transport phenomena in quantum systems that are beyond the standard paradigms
of classical physics. Here, we discuss features of spin-orbit dynamics that can
be visualized using a classical model with two coupled angular degrees of freedom.
Specifically, we demonstrate classical ‘spin’ filtering through our model and
show that the interplay between angular degrees of freedom and dissipation can
lead to asymmetric ‘spin’ transport.

text: Atom-based quantum simulators have had many successes in tackling challenging
quantum many-body problems, owing to the precise and dynamical control that they
provide over the systems' parameters. They are, however, often optimized to address
a specific type of problem. Here, we present the design and implementation of
a 6Li-based quantum gas platform that provides wide-ranging capabilities and is
able to address a variety of quantum many-body problems. Our two-chamber architecture
relies on a robust combination of gray molasses and optical transport from a laser-cooling
chamber to a glass cell with excellent optical access. There, we first create
unitary Fermi superfluids in a three-dimensional axially symmetric harmonic trap
and characterize them using in situ thermometry, reaching temperatures below 20
nK. This allows us to enter the deep superfluid regime with samples of extreme
diluteness, where the interparticle spacing is sufficiently large for direct single-atom
imaging. Second, we generate optical lattice potentials with triangular and honeycomb
geometry in which we study diffraction of molecular Bose-Einstein condensates,
and show how going beyond the Kapitza-Dirac regime allows us to unambiguously
distinguish between the two geometries. With the ability to probe quantum many-body
physics in both discrete and continuous space, and its suitability for bulk and
single-atom imaging, our setup represents an important step towards achieving
a wide-scope quantum simulator.

interior regularity of the 2D Navier–Stokes equations with inhomogeneous stochastic
boundary conditions. The noise, white in time and coloured in space, can be interpreted
as the physical law describing the driving mechanism on the atmosphere–ocean interface,
i.e. as a balance of the shear stress of the ocean and the horizontal wind force.

text: Speciation is a key evolutionary process that is not yet fully understood.
Combining population genomic and ecological data from multiple diverging pairs
of marine snails (Littorina) supports the search for speciation mechanisms. Placing
pairs on a one-dimensional speciation continuum, from undifferentiated populations
to species, obscured the complexity of speciation. Adding multiple axes helped
to describe either speciation routes or reproductive isolation in the snails.
Divergent ecological selection repeatedly generated barriers between ecotypes,
but appeared less important in completing speciation while genetic incompatibilities
played a key role. Chromosomal inversions contributed to genomic barriers, but
with variable impact. A multidimensional (hypercube) approach supported framing
of questions and identification of knowledge gaps and can be useful to understand
speciation in many other systems.

text: As a key liquid organic hydrogen carrier, investigating the decomposition
of formic acid (HCOOH) on the Pd (1 1 1) transition metal surface is imperative
for harnessing hydrogen energy. Despite a multitude of studies, the major mechanisms
and key intermediates involved in the dehydrogenation process of formic acid remain
a great topic of debate due to ambiguous adsorbate interactions. In this research,
we develop an advanced microkinetic model based on first-principles calculations,
accounting for adsorbate–adsorbate interactions. Our study unveils a comprehensive
mechanism for the Pd (1 1 1) surface, highlighting the significance of coverage
effects in formic acid dehydrogenation. Our findings unequivocally demonstrate
that H coverage on the Pd (1 1 1) surface renders formic acid more susceptible
to decompose into H2 and CO2 through COOH intermediates. Consistent with experimental
results, the selectivity of H2 in the decomposition of formic acid on the Pd (1
1 1) surface approaches 100 %. Considering the influence of H coverage, our kinetic
analysis aligns perfectly with experimental values at a temperature of 373 K.

text: Cell division in all domains of life requires the orchestration of many proteins,
but in Archaea most of the machinery remains poorly characterized. Here we investigate
the FtsZ-based cell division mechanism in Haloferax volcanii and find proteins
containing photosynthetic reaction centre (PRC) barrel domains that play an essential
role in archaeal cell division. We rename these proteins cell division protein
B 1 (CdpB1) and CdpB2. Depletions and deletions in their respective genes cause
severe cell division defects, generating drastically enlarged cells. Fluorescence
microscopy of tagged FtsZ1, FtsZ2 and SepF in CdpB1 and CdpB2 mutant strains revealed
an unusually disordered divisome that is not organized into a distinct ring-like
structure. Biochemical analysis shows that SepF forms a tripartite complex with
CdpB1/2 and crystal structures suggest that these two proteins might form filaments,
possibly aligning SepF and the FtsZ2 ring during cell division. Overall our results
indicate that PRC-domain proteins play essential roles in FtsZ-based cell division
in Archaea.

text: For some k∈Z≥0∪{∞}, we call a linear forest k-bounded if each of its components
has at most k edges. We will say a (k,ℓ)-bounded linear forest decomposition of
a graph G is a partition of E(G) into the edge sets of two linear forests Fk,Fℓ
where Fk is k-bounded and Fℓ is ℓ-bounded. We show that the problem of deciding
whether a given graph has such a decomposition is NP-complete if both k and ℓ
are at least 2, NP-complete if k≥9 and ℓ=1, and is in P for (k,ℓ)=(2,1). Before
this, the only known NP-complete cases were the (2,2) and (3,3) cases. Our hardness
result answers a question of Bermond et al. from 1984. We also show that planar
graphs of girth at least nine decompose into a linear forest and a matching, which
in particular is stronger than 3-edge-colouring such graphs.
acknowledgement: We wish to thank Dániel Marx and András Sebő for making us aware
of the results in [8] and some clarifications on them.

text: We perform a diagrammatic analysis of the energy of a mobile impurity immersed
in a strongly interacting two-component Fermi gas to second order in the impurity-bath
interaction. These corrections demonstrate divergent behavior in the limit of
large impurity momentum. We show the fundamental processes responsible for these
logarithmically divergent terms. We study the problem in the general case without
any assumptions regarding the fermion-fermion interactions in the bath. We show
that the divergent term can be summed up to all orders in the Fermi-Fermi interaction
and that the resulting expression is equivalent to the one obtained in the few-body
calculation. Finally, we provide a perturbative calculation to the second order
in the Fermi-Fermi interaction, and we show the diagrams responsible for these
terms.

text: 'The James Webb Space Telescope is revealing a new population of dust-reddened
broad-line active galactic nuclei (AGN) at redshifts z ≳ 5. Here we present deep
NIRSpec/Prism spectroscopy from the Cycle 1 Treasury program Ultradeep NIRSpec
and NIRCam ObserVations before the Epoch of Reionization (UNCOVER) of 15 AGN candidates
selected to be compact, with red continua in the rest-frame optical but with blue
slopes in the UV. From NIRCam photometry alone, they could have been dominated
by dusty star formation or an AGN. Here we show that the majority of the compact
red sources in UNCOVER are dust-reddened AGN: 60% show definitive evidence for
broad-line Hα with a FWHM > 2000 km s −1, 20% of the current data are inconclusive,
and 20% are brown dwarf stars. We propose an updated photometric criterion to
select red z > 5 AGN that excludes brown dwarfs and is expected to yield >80%
AGN. Remarkably, among all zphot > 5 galaxies with F277W – F444W > 1 in UNCOVER
at least 33% are AGN regardless of compactness, climbing to at least 80% AGN for
sources with F277W – F444W > 1.6. The confirmed AGN have black hole masses of
107–109M⊙. While their UV luminosities (−16 > MUV > −20 AB mag) are low compared
to UV-selected AGN at these epochs, consistent with percent-level scattered AGN
light or low levels of unobscured star formation, the inferred bolometric luminosities
are typical of 107–109M⊙ black holes radiating at ∼10%–40% the Eddington limit.
The number densities are surprisingly high at ∼10−5 Mpc−3 mag−1, 100 times more
common than the faintest UV-selected quasars, while accounting for ∼1% of the
UV-selected galaxies. While their UV faintness suggests they may not contribute
strongly to reionization, their ubiquity poses challenges to models of black hole
growth.'

text: The brain’s functionality is developed and maintained through synaptic plasticity.
As synapses undergo plasticity, they also affect each other. The nature of such
‘co-dependency’ is difficult to disentangle experimentally, because multiple synapses
must be monitored simultaneously. To help understand the experimentally observed
phenomena, we introduce a framework that formalizes synaptic co-dependency between
different connection types. The resulting model explains how inhibition can gate
excitatory plasticity while neighboring excitatory–excitatory interactions determine
the strength of long-term potentiation. Furthermore, we show how the interplay
between excitatory and inhibitory synapses can account for the quick rise and
long-term stability of a variety of synaptic weight profiles, such as orientation
tuning and dendritic clustering of co-active synapses. In recurrent neuronal networks,
co-dependent plasticity produces rich and stable motor cortex-like dynamics with
high input sensitivity. Our results suggest an essential role for the neighborly
synaptic interaction during learning, connecting micro-level physiology with network-wide
phenomena.

text: 'We propose a novel approach to concentration for non-independent random variables.
The main idea is to “pretend” that the random variables are independent and pay
a multiplicative price measuring how far they are from actually being independent.
This price is encapsulated in the Hellinger integral between the joint and the
product of the marginals, which is then upper bounded leveraging tensorisation
properties. Our bounds represent a natural generalisation of concentration inequalities
in the presence of dependence: we recover exactly the classical bounds (McDiarmid’s
inequality) when the random variables are independent. Furthermore, in a “large
deviations” regime, we obtain the same decay in the probability as for the independent
case, even when the random variables display non-trivial dependencies. To show
this, we consider a number of applications of interest. First, we provide a bound
for Markov chains with finite state space. Then, we consider the Simple Symmetric
Random Walk, which is a non-contracting Markov chain, and a non-Markovian setting
in which the stochastic process depends on its entire past. To conclude, we propose
an application to Markov Chain Monte Carlo methods, where our approach leads to
an improved lower bound on the minimum burn-in period required to reach a certain
accuracy. In all of these settings, we provide a regime of parameters in which
our bound fares better than what the state of the art can provide.'

text: We demonstrate the failure of the adiabatic Born-Oppenheimer approximation
to describe the ground state of a quantum impurity within an ultracold Fermi gas
despite substantial mass differences between the bath and impurity species. Increasing
repulsion leads to the appearance of nonadiabatic couplings between the fast bath
and slow impurity degrees of freedom, which reduce the parity symmetry of the
latter according to the pseudo Jahn-Teller effect. The presence of this mechanism
is associated to a conical intersection involving the impurity position and the
inverse of the interaction strength, which acts as a synthetic dimension. We elucidate
the presence of these effects via a detailed ground-state analysis involving the
comparison of ab initio fully correlated simulations with effective models. Our
study suggests ultracold atomic ensembles as potent emulators of complex molecular
phenomena.
