text: Dielectric resonators are open systems whose eigenmodes couple to the radiation
continuum resulting in nonzero radiation losses. For a long time, it was believed
that only guided modes with frequencies below the light line were decoupled from
the radiation continuum [1] . In the early 2000’s, several counterexamples of
perfectly localized states – i.e. totally decoupled from the radiation continuum
– at frequencies above the light line were proposed in dielectric gratings and
photonic crystal waveguides [2] . Such states are known as bound states in the
continuum (BIC) .

text: Combinatorial problems, such as the Ising problem, are hard to solve with
conventional electronics. Photonic systems have recently been proposed as an efficient
platform to solve these problems faster and more efficiently, thus calling for
the development of featured algorithms to run on photonic machines. A few recent
findings, including the Photonic Recurrent Ising Sampler, a photonic machine that
recurrently solves arbitrary Ising problems, will be presented in this talk, along
with their experimental realizations in various platforms.

text: 'Periodic wavelength-scale surface patterns have long been used in the context
of lasing and spontaneous emission to enhance emission by light trapping (distributed
Bragg resonances). Buried within these well-known devices, however, are theoretical
mysteries that are still being unravelled. A periodic surface grating actually
creates a continuum of resonant modes, so what determines which single mode (if
any) lases? Technically, what determines the stability of a periodic lasing mode:
is it only the finite size of a surface that allows single-mode lasing, or can
it arise for arbitrarily large structures? More generally, if one continuously
deforms an unpatterned surface to maximize light emission, how is the symmetry
broken and what optimal structures arise? We address these questions by combining
new computational techniques for modeling and large-scale optimization of incoherent
emission and lasing with new analytical results arising from perturbation and
stability theory.'

text: Donor–acceptor Stenhouse adducts (DASAs) are visible‐light‐responsive photoswitches
with a variety of emerging applications in photoresponsive materials. Their two‐step
modular synthesis, centered on the nucleophilic ring opening of an activated furan,
makes DASAs readily accessible. However, the use of less reactive donors or acceptors
renders the process slow and low yielding, which has limited their development.
We demonstrate here that 1,1,1,3,3,3‐hexafluoro‐2‐propanol (HFIP) promotes the
ring‐opening reaction and stabilizes the open isomer, allowing greatly reduced
reaction times and increased yields for known derivatives. In addition, it provides
access to previously unattainable DASA‐based photoswitches and DASA–polymer conjugates.
The role of HFIP and the photochromic properties of a set of new DASAs is probed
using a combination of 1H NMR and UV/Vis spectroscopy. The
use of sterically hindered, electron‐poor amines enabled the dark equilibrium
to be decoupled from closed‐isomer half‐lives for the first time.

text: A convenient approach for the synthesis of foldable redox-active flavin peptide
conjugates was established. A model β-hairpin oligopeptide motif was utilized
to demonstrate that azidolysine side-chains are readily functionalised with an
alkyne-bearing flavine derivative. The folding equilibrium of the peptide backbone
as well as the redox behaviour of the flavin moieties remains intact after the
conjugation.

text: The effects of solution‐state dielectric and intermolecular interactions on
the degree of charge separation provide a route to understanding the switching
properties and concentration dependence of donor–acceptor Stenhouse adducts (DASAs).
Through solvatochromic analysis of the open‐form DASA in conjunction with X‐ray
diffraction and computational theory, we have analyzed the ionic character of
a series of DASAs. First‐ and third‐generation architectures lead to a higher
zwitterionic resonance contribution of the open form and a zwitterionic closed
form, whereas the second‐generation architecture possesses a less charge‐separated
open form and neutral closed form. This can be correlated with equilibrium control
and photoswitching solvent compatibility. As a result of the high contribution
of the zwitterionic resonance forms of first‐ and third‐generation DASAs, we were
able to control their switching kinetics by means of ion concentration, whereas
second‐generation DASAs were less affected. Importantly, these results show how
the previously reported concentration dependence of DASAs is not universal, and
that DASAs with a more hybrid structure in the open form can achieve photoswitching
at high concentrations.

text: 'A new Diels−Alder (DA)-based photopatterning platform is presented, which
exploits the irreversible, light-induced decarbonylation and subsequent cleavage
of cyclopentadienone−norbornadiene (CPD−NBD) adducts. A series of CPD−NBD adducts
have been prepared and systematically studied toward the use in a polymeric material
photopatterning platform. By incorporating an optimized CPD−NBD adduct into polymer
networks, it is demonstrated that cyclopentadiene may be unveiled upon 365 nm
irradiation and subsequently clicked to a variety of maleimides with spatial control
under mild reaction conditions and with fast kinetics. Unlike currently available
photoinduced Diels−Alder reactions that rely on trapping transient, photocaged
dienes, this platform introduces a persistent, yet highly reactive diene after
irradiation, enabling the use of photosensitive species such as cyanine dyes to
be patterned. To highlight the potential use of this platform in a variety of
material applications, we demonstrate two proof-of-concepts: patterned conjugation
of multiple dyes into apolyacrylate network and preprogrammed ligation of streptavidin
into poly(ethylene glycol) hydrogels.'

text: Photosurfactants have shown considerable promise for enabling stimuli-responsive
control of the properties and motion of fluid interfaces. Recently, a number of
photoswitch chemistries have emerged to tailor the photoresponsive properties
of photosurfactants. However, systematic studies investigating how photoresponsive
surfactant behavior depends on the photochemical and photophysical properties
of the switch remain scarce. In this work, we develop synthetic schemes and surfactant
designs to produce a well-controlled library of photosurfactants to comparatively
assess the behavior of photoswitch chemistry on interfacial behavior. We employ
photoinduced spreading of droplets at fluid interfaces as a model for such studies.
We show that although photosurfactant response is largely guided by expected trends
with changes in polarity of the photoswitch, interfacial behavior also depends
nontrivially and sometimes counter-intuitively on the kinetics and mechanisms
of photoswitching, particularly at the interface of two solvents, as well as on
complex interactions with other surfactants. Understanding these complexities
enables the design of new photosurfactant systems and their optimization toward
responsive functions including triggered spreading, dewetting, and destabilization
of droplets on solid and fluid surfaces.

text: Coulombic interactions can be used to assemble charged nanoparticles into
higher-order structures, but the process requires oppositely charged partners
that are similarly sized. The ability to mediate the assembly of such charged
nanoparticles using structurally simple small molecules would greatly facilitate
the fabrication of nanostructured materials and harnessing their applications
in catalysis, sensing and photonics. Here we show that small molecules with as
few as three electric charges can effectively induce attractive interactions between
oppositely charged nanoparticles in water. These interactions can guide the assembly
of charged nanoparticles into colloidal crystals of a quality previously only
thought to result from their co-crystallization with oppositely charged nanoparticles
of a similar size. Transient nanoparticle assemblies can be generated using positively
charged nanoparticles and multiply charged anions that are enzymatically hydrolysed
into mono- and/or dianions. Our findings demonstrate an approach for the facile
fabrication, manipulation and further investigation of static and dynamic nanostructured
materials in aqueous environments.

text: DNA nanotechnology offers a versatile toolbox for precise spatial and temporal
manipulation of matter on the nanoscale. However, rendering DNA-based systems
responsive to light has remained challenging. Herein, we describe the remote manipulation
of native (non-photoresponsive) chiral plasmonic molecules (CPMs) using light.
Our strategy is based on the use of a photoresponsive medium comprising a merocyanine-based
photoacid. Upon exposure to visible light, the medium decreases its pH, inducing
the formation of DNA triplex links, leading to a spatial reconfiguration of the
CPMs. The process can be reversed simply by turning the light off and it can be
repeated for multiple cycles. The degree of the overall chirality change in an
ensemble of CPMs depends on the CPM fraction undergoing reconfiguration, which,
remarkably, depends on and can be tuned by the intensity of incident light. Such
a dynamic, remotely controlled system could aid in further advancing DNA-based
devices and nanomaterials.

text: Dissipative self-assembly is ubiquitous in nature, where it gives rise to
complex structures and functions such as self-healing, homeostasis, and camouflage.
These phenomena are enabled by the continuous conversion of energy stored in chemical
fuels, such as ATP. Over the past decade, an increasing number of synthetic chemically
driven systems have been reported that mimic the features of their natural counterparts.
At the same time, it has been shown that dissipative self-assembly can also be
fueled by light; these optically fueled systems have been developed in parallel
to the chemically fueled ones. In this perspective, we critically compare these
two classes of systems. Despite the complementarity and fundamental differences
between these two modes of dissipative self-assembly, our analysis reveals that
multiple analogies exist between chemically and light-fueled systems. We hope
that these considerations will facilitate further development of the field of
dissipative self-assembly.

text: 'Inorganic nanoparticles (NPs) exhibit a wide range of fascinating physicochemical
properties, many of which can be controlled by modulating the NP–NP coupling.
Controlling the self-assembly of NPs using light has traditionally been achieved
by functionalizing their surfaces with monolayers of photoswitchable molecules,
which can be reversibly isomerized between two or more states upon exposure to
different wavelengths of light. NPs whose assembly can be controlled by light
in a reversible fashion can find interesting applications. The chapter deals with
systems comprising mixtures of non-photoswitchable NPs and small-molecule photoacids
and photobases. Examples of light-controlled self-assembly of NPs hitherto reported
have been categorized into six distinct approaches. These are: functionalizing
NPs with monolayers of photoswitchable molecules, light-controlled adsorption/desorption
of photoswitchable molecules onto NPs, and light-induced electron transfer between
the particle''s inorganic core and the NP-bound ligands.'

text: Most massive stars are born in binaries close enough for mass transfer episodes.
These modify the appearance, structure, and future evolution of both stars. We
compute the evolution of a 100-day-period binary, consisting initially of a 25
M⊙ star and a 17 M⊙ star, which experiences stable mass transfer. We focus on
the impact of mass accretion on the surface composition, internal rotation, and
structure of the accretor. To anchor our models, we show that our accretor broadly
reproduces the properties of ζ Ophiuchi, which has long been proposed to have
accreted mass before being ejected as a runaway star when the companion exploded.
We compare our accretor to models of single rotating stars and find that the later
and stronger spin-up provided by mass accretion produces significant differences.
Specifically, the core of the accretor retains higher spin at the end of the main
sequence, and a convective layer develops that changes its density profile. Moreover,
the surface of the accretor star is polluted by CNO-processed material donated
by the companion. Our models show effects of mass accretion in binaries that are
not captured in single rotating stellar models. This possibly impacts the further
evolution (either in a binary or as single stars), the final collapse, and the
resulting spin of the compact object.

text: Helium star–carbon-oxygen white dwarf (CO WD) binaries are potential single-degenerate
progenitor systems of thermonuclear supernovae. Revisiting a set of binary evolution
calculations using the stellar evolution code MESA, we refine our previous predictions
about which systems can lead to a thermonuclear supernova and then characterize
the properties of the helium star donor at the time of explosion. We convert these
model properties to near-UV/optical magnitudes assuming a blackbody spectrum and
support this approach using a matched stellar atmosphere model. These models will
be valuable to compare with pre-explosion imaging for future supernovae, though
we emphasize the observational difficulty of detecting extremely blue companions.
The pre-explosion source detected in association with SN 2012Z has been interpreted
as a helium star binary containing an initially ultra-massive WD in a multiday
orbit. However, extending our binary models to initial CO WD masses of up to 1.2
M⊙, we find that these systems undergo off-center carbon ignitions and thus are
not expected to produce thermonuclear supernovae. This tension suggests that,
if SN 2012Z is associated with a helium star–WD binary, then the pre-explosion
optical light from the system must be significantly modified by the binary environment
and/or the WD does not have a carbon-rich interior composition.

text: The majority of massive stars live in binary or multiple systems and will
interact with a companion during their lifetimes, which helps to explain the observed
diversity of core-collapse supernovae. Donor stars in binary systems can lose
most of their hydrogen-rich envelopes through mass transfer. As a result, not
only are the surface properties affected, but so is the core structure. However,
most calculations of the core-collapse properties of massive stars rely on single-star
models. We present a systematic study of the difference between the pre-supernova
structures of single stars and stars of the same initial mass (11–21 M⊙) that
have been stripped due to stable post-main-sequence mass transfer at solar metallicity.
We present the pre-supernova core composition with novel diagrams that give an
intuitive representation of the isotope distribution. As shown in previous studies,
at the edge of the carbon-oxygen core, the binary-stripped star models contain
an extended gradient of carbon, oxygen, and neon. This layer remains until core
collapse and is more extended in mass for higher initial stellar masses. It originates
from the receding of the convective helium core during core helium burning in
binary-stripped stars, which does not occur in single-star models. We find that
this same evolutionary phase leads to systematic differences in the final density
and nuclear energy generation profiles. Binary-stripped star models have systematically
higher total masses of carbon at the moment of core collapse compared to single-star
models, which likely results in systematically different supernova yields. In
about half of our models, the silicon-burning and oxygen-rich layers merge after
core silicon burning. We discuss the implications of our findings for the “explodability”,
supernova observations, and nucleosynthesis of these stars. Our models are publicly
available and can be readily used as input for detailed supernova simulations.

text: While most simulations of the epoch of reionization have focused on single-stellar
populations in star-forming dwarf galaxies, products of binary evolution are expected
to significantly contribute to emissions of hydrogen-ionizing photons. Among these
products are stripped stars (or helium stars), which have their envelopes stripped
from interactions with binary companions, leaving an exposed helium core. Previous
work has suggested these stripped stars can dominate the Lyman Continuum (LyC)
photon output of high-redshift, low-luminosity galaxies post-starburst. Other
sources of hard radiation in the early universe include zero-metallicity Population
iii stars, which may have similar spectral energy distribution (SED) properties
to galaxies with radiation dominated by stripped-star emissions. Here, we use
four metrics (the power-law exponent over wavelength intervals 240–500 Å, 600–900
Å, and 1200–2000 Å, and the ratio of total luminosity in FUV wavelengths to LyC
wavelengths) to compare the SEDs of simulated galaxies with only single-stellar
evolution, galaxies containing stripped stars, and galaxies containing Population
iii stars, with four different initial mass functions (IMFs). We find that stripped
stars significantly alter SEDs in the LyC range of galaxies at the epoch of reionization.
SEDs in galaxies with stripped stars have lower power-law indices in the LyC range
and lower FUV to LyC luminosity ratios. These differences in SEDs are present
at all considered luminosities (${M}_{\mathrm{UV}}\gt -15$, AB system), and are
most pronounced for lower-luminosity galaxies. Intrinsic SEDs as well as those
with interstellar medium absorption of galaxies with stripped stars and Population
iii stars are found to be distinct for all tested Population iii IMFs.

text: "Context. Observations of massive stars in open clusters younger than ∼8 Myr
have shown that a majority of them are in binary systems, most of which will interact
during their life. While these can be used as a proxy of the initial multiplicity
properties, studying populations of massive stars older than ∼20 Myr allows us
to probe the outcome of these interactions after a significant number of systems
have experienced mass and angular momentum transfer and may even have merged.\r\n\r\nAims.
Using multi-epoch integral-field spectroscopy, we aim to investigate the multiplicity
properties of the massive-star population in the dense core of the ∼40 Myr old
cluster NGC 330 in the Small Magellanic Cloud in order to search for possible
imprints of stellar evolution on the multiplicity properties.\r\n\r\nMethods.
We obtained six epochs of VLT/MUSE observations operated in wide-field mode with
the extended wavelength setup and supported by adaptive optics. We extracted spectra
and measured radial velocities for stars brighter than mF814W = 19. We identified
single-lined spectroscopic binaries through significant RV variability with a
peak-to-peak amplitude larger than 20 km s−1. We also identified double-lined
spectroscopic binaries, and quantified the observational biases for binary detection.
In particular, we took into account that binary systems with similar line strengths
are difficult to detect in our data set.\r\n\r\nResults. The observed spectroscopic
binary fraction among stars brighter than mF814W = 19 (approximately 5.5 M⊙ on
the main sequence) is fSBobs = 13.2 ± 2.0%. Considering period and mass ratio
ranges from log(P) = 0.15−3.5 (about 1.4 to 3160 d), q = 0.1−1.0, and a representative
set of orbital parameter distributions, we find a bias-corrected close binary
fraction of fcl = 34−7+8%. This fraction seems to decline for the fainter stars,
which indicates either that the close binary fraction drops in the B-type domain,
or that the period distribution becomes more heavily weighted toward longer orbital
periods. We further find that both fractions vary strongly in different regions
of the color-magnitude diagram, which corresponds to different evolutionary stages.
This probably reveals the imprint of the binary history of different groups of
stars. In particular, we find that the observed spectroscopic binary fraction
of Be stars (fSBobs = 2 ± 2%) is significantly lower than that of B-type stars
(fSBobs = 9 ± 2%).\r\n\r\nConclusions. We provide the first homogeneous radial
velocity study of a large sample of B-type stars at a low metallicity ([Fe/H]
≲ −1.0). The overall bias-corrected close binary fraction (log(P) < 3.5 d) of
the B-star population in NGC 330 is lower than the fraction reported for younger
Galactic and Large Magellanic Cloud clusters in previous works. More data are
needed, however, to establish whether the observed differences are caused by an
age or a metallicity effect."

text: Most massive stars experience binary interactions in their lifetimes that
can alter both the surface and core structure of the stripped star with significant
effects on their ultimate fate as core-collapse supernovae. However, core-collapse
supernovae simulations to date have focused almost exclusively on the evolution
of single stars. We present a systematic simulation study of single and binary-stripped
stars with the same initial mass as candidates for core-collapse supernovae (11–21
M⊙). Generally, we find that binary-stripped stars core tend to have a smaller
compactness parameter, with a more prominent, deeper silicon/oxygen interface,
and explode preferentially to the corresponding single stars of the same initial
mass. Such a dichotomy of behavior between these two modes of evolution would
have important implications for supernovae statistics, including the final neutron
star masses, explosion energies, and nucleosynthetic yields. Binary-stripped remnants
are also well poised to populate the possible mass gap between the heaviest neutron
stars and the lightest black holes. Our work presents an improvement along two
fronts, as we self-consistently account for the pre-collapse stellar evolution
and the subsequent explosion outcome. Even so, our results emphasize the need
for more detailed stellar evolutionary models to capture the sensitive nature
of explosion outcome.
