text: Controlling the size and shape of assembled structures is a fundamental challenge
in self-assembly and is highly relevant in material design and biology. Here,
we show that specific but promiscuous short-range binding interactions make it
possible to economically assemble linear filaments of user-defined length. Our
approach leads to independent control over the mean and width of the filament
size distribution and allows us to smoothly explore design trade-offs between
assembly quality (spread in size) and cost (number of particle species). We employ
a simple hierarchical assembly protocol to minimize assembly times and show that
multiple stages of hierarchy make it possible to extend our approach to the assembly
of higher-dimensional structures. Our work provides a conceptually simple solution
to size control that is applicable to a broad range of systems, from DNA nanoparticles
to supramolecular polymers and beyond.

text: Analog quantum simulators provide access to many-body dynamics beyond the
reach of classical computation. However, extracting physical insights from experimental
data is often hindered by measurement noise, limited observables, and incomplete
knowledge of the underlying microscopic model. Here, we develop a machine learning
approach based on a variational autoencoder (VAE) to analyze interference measurements
of tunnel-coupled one-dimensional Bose gases, which realize the sine-Gordon quantum
field theory. Trained in an unsupervised manner, the VAE learns a minimal latent
representation that strongly correlates with the equilibrium control parameter
of the system. Applied to nonequilibrium protocols, the latent space uncovers
signatures of frozen-in solitons following rapid cooling, and reveals anomalous
postquench dynamics not captured by conventional correlation-based methods. These
results demonstrate that generative models can extract physically interpretable
variables directly from noisy and sparse experimental data, providing complementary
probes of equilibrium and nonequilibrium physics in quantum simulators. More broadly,
our work highlights how machine learning can supplement established field-theoretical
techniques, paving the way for scalable, data-driven discovery in quantum many-body
systems.

text: Non-Hermitian many-body localization (NH MBL) has emerged as a possible scenario
for stable localization in open systems, as suggested by spectral indicators identifying
a putative transition for finite system sizes. In this work, we shift the focus
to dynamical probes, specifically the steady-state spin current, to investigate
transport properties in a disordered, non-Hermitian XXZ spin chain. Through exact
diagonalization for small systems and tensor-network methods for larger chains,
we demonstrate that the steady-state current remains finite and decays exponentially
with disorder strength, showing no evidence of a transition up to disorder values
far beyond the previously claimed critical point. Our results reveal a stark discrepancy
between spectral indicators, which suggest localization, and transport behavior,
which indicates delocalization. This highlights the importance of dynamical observables
in characterizing NH MBL and suggests that traditional spectral measures may not
fully capture the physics of non-Hermitian systems. Additionally, we observe a
noncommutativity of limits in system size and time, further complicating the interpretation
of finite-size studies. These findings challenge the existence of NH MBL in the
studied model and underscore the need for alternative approaches to understanding
localization in non-Hermitian settings.

text: The conversion of thermal energy into work is usually more efficient in the
slow-driving regime, where the power output is vanishingly small. Efficient work
extraction for fast-driving protocols remains an outstanding challenge at the
nanoscale, where fluctuations play a significant role. In this Letter, we use
a quantum-dot Szilard engine to extract work from thermal fluctuations with maximum
efficiency over two decades of driving speed. We design and implement a family
of optimized protocols ranging from the slow- to the fast-driving regime, and
we measure the engine's efficiency as well as the mean and variance of its power
output in each case. These optimized protocols exhibit significant improvements
in power and efficiency compared to the naive approach. Our results also show
that, when optimizing for efficiency, boosting the power output of a Szilard engine
inevitably comes at the cost of increased power fluctuations.

text: It is a basic principle that an effect cannot come before the cause. Dispersive
relations that follow from this fundamental fact have proven to be an indispensable
tool in physics and engineering. They are most powerful in the domain of linear
response where they are known as Kramers-Kronig relations. However, when it comes
to nonlinear phenomena the implications of causality are much less explored, apart
from several notable exceptions. Here in this paper we demonstrate how to apply
the dispersive formalism to analyze the ultrafast nonlinear response in the context
of the paradigmatic nonlinear Kerr effect. We find that the requirement of causality
introduces a noticeable effect even under assumption that Kerr effect is mediated
by quasi-instantaneous off-resonant electronic hyperpolarizability. We confirm
this by experimentally measuring the time-resolved Kerr dynamics in GaAs by means
of a hybrid pump-probe Mach-Zehnder interferometer and demonstrate the presence
of an intrinsic lagging between amplitude and phase responses as predicted by
dispersive analysis. Our results describe a general property of the time-resolved
nonlinear processes thereby highlighting the importance of accounting for dispersive
effects in the nonlinear optical processes involving ultrashort pulses.

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.

text: Quantum computers are increasing in size and quality but are still very noisy.
Error mitigation extends the size of the quantum circuits that noisy devices can
meaningfully execute. However, state-of-the-art error mitigation methods are hard
to implement and the limited qubit connectivity in superconducting qubit devices
restricts most applications to the hardware's native topology. Here we show a
quantum approximate optimization algorithm (QAOA) on nonplanar random regular
graphs with up to 40 nodes enabled by a machine learning-based error mitigation.
We use a swap network with careful decision-variable-to-qubit mapping and a feed-forward
neural network to optimize a depth-two QAOA on up to 40 qubits. We observe a meaningful
parameter optimization for the largest graph which requires running quantum circuits
with 958 two-qubit gates. Our paper emphasizes the need to mitigate samples, and
not only expectation values, in quantum approximate optimization. These results
are a step towards executing quantum approximate optimization at a scale that
is not classically simulable. Reaching such system sizes is key to properly understanding
the true potential of heuristic algorithms like QAOA.

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.

text: Josephson diodes are superconducting elements that show an asymmetry in the
critical current depending on the direction of the current. Here, we theoretically
explore how an alternating current bias can tune the response of such a diode.
We show that for slow driving there is always a regime where the system can only
carry zero-voltage dc current in one direction, thus effectively behaving as an
ideal Josephson diode. Under fast driving, the diode efficiency is also tunable,
although the ideal regime cannot be reached in this case. We also investigate
the residual dissipation due to the time-dependent current bias and show that
it remains small. All our conclusions are solely based on the critical current
asymmetry of the junction, and are thus compatible with any Josephson diode.

text: 'We report on dynamic Shubnikov–de Haas (SdH) oscillations that are measured
in the optical response, subterahertz transmittance of two-dimensional systems,
and reveal two distinct types of oscillation nodes: “universal” nodes at integer
ratios of radiation and cyclotron frequencies and “tunable” nodes at positions
sensitive to all parameters of the structure. The nodes in both real and imaginary
parts of the measured complex transmittance are analyzed using a dynamic version
of the static Lifshitz-Kosevich formula. These results demonstrate that the node
structure of the dynamic SdH oscillations provides an all-optical access to quantization-
and interaction-induced renormalization effects, in addition to parameters one
can obtain from the static SdH oscillations.'

text: The process of polymer condensation, i.e., the formation of bonds between
reactive end groups, is ubiquitous in both industry and biology. Here we study
generic systems undergoing polymer condensation in competition with cyclization.
Using a generalized Smoluchowski theory, molecular dynamics simulations and experiments
with DNA and ATP-consuming T4 ligase, we find that this system displays a transition,
from a ring-dominated regime with finite-length chains at infinite time to a linear-polymers-dominated
one with chains that keep growing in time. Finally, we show that fluids prepared
close to the transition may have widely different compositions and rheology at
large condensation times.

text: We present a theory describing the interaction of structured light, such as
light carrying orbital angular momentum, with molecules. The light-matter interaction
Hamiltonian we derive is expressed through couplings between spherical gradients
of the electric field and the (transition) electric multipole moments of a particle
of any nontrivial rotation point group. Our model can therefore accommodate an
arbitrary complexity of the molecular and electric field structure, and it can
be straightforwardly extended to atoms or nanostructures. Applying this framework
to rovibrational spectroscopy of molecules, we uncover the general mechanism of
angular momentum exchange between the spin and orbital angular momenta of light,
molecular rotation, and its center-of-mass motion. We show that the nonzero vorticity
of Laguerre-Gaussian beams can strongly enhance certain rovibrational transitions
that are considered forbidden in the case of nonhelical light. We discuss the
experimental requirements for the observation of these forbidden transitions in
state-of-the-art spatially resolved spectroscopy measurements.

text: Precision sensing and manipulation of milligram-scale mechanical oscillators
has attracted growing interest in the fields of table-top explorations of gravity
and tests of quantum mechanics at macroscopic scales. Torsional oscillators present
an opportunity in this regard due to their remarked isolation from environmental
noise. For torsional motion, an effective employment of optical cavities to enhance
optomechanical interactions—as already established for linear oscillators—so far
faced certain challenges. Here, we propose a concept for sensing and manipulating
torsional motion, where exclusively the torsional rotations of a pendulum are
mapped onto the path length of a single two-mirror optical cavity. The concept
inherently alleviates many limitations of previous approaches. A proof-of-principle
experiment is conducted with a rigidly controlled pendulum to explore the sensing
aspects of the concept and to identify practical limitations in a potential state-of-the
art setup. Based on this study, we anticipate development of precision torque
sensors utilizing torsional pendulums that can support sensitivities below 10−19Nm/√Hz,
while the motion of the pendulums are dominated by quantum radiation pressure
noise at sub-microwatts of incoming laser power. These developments will provide
horizons for experiments at the interface of quantum mechanics and gravity.
