text: We investigate the capabilities of Physics-Informed Neural Networks (PINNs)
to reconstruct turbulent Rayleigh–Bénard flows using only temperature information.
We perform a quantitative analysis of the quality of the reconstructions at various
amounts of low-passed-filtered information and turbulent intensities. We compare
our results with those obtained via nudging, a classical equation-informed data
assimilation technique. At low Rayleigh numbers, PINNs are able to reconstruct
with high precision, comparable to the one achieved with nudging. At high Rayleigh
numbers, PINNs outperform nudging and are able to achieve satisfactory reconstruction
of the velocity fields only when data for temperature is provided with high spatial
and temporal density. When data becomes sparse, the PINNs performance worsens,
not only in a point-to-point error sense but also, and contrary to nudging, in
a statistical sense, as can be seen in the probability density functions and energy
spectra.

text: Interstitial fluid (IF) accumulation between embryonic cells is thought to
be important for embryo patterning and morphogenesis. Here, we identify a positive
mechanical feedback loop between cell migration and IF relocalization and find
that it promotes embryonic axis formation during zebrafish gastrulation. We show
that anterior axial mesendoderm (prechordal plate [ppl]) cells, moving in between
the yolk cell and deep cell tissue to extend the embryonic axis, compress the
overlying deep cell layer, thereby causing IF to flow from the deep cell layer
to the boundary between the yolk cell and the deep cell layer, directly ahead
of the advancing ppl. This IF relocalization, in turn, facilitates ppl cell protrusion
formation and migration by opening up the space into which the ppl moves and,
thereby, the ability of the ppl to trigger IF relocalization by pushing against
the overlying deep cell layer. Thus, embryonic axis formation relies on a hydraulic
feedback loop between cell migration and IF relocalization.

text: The angulon, a quasiparticle formed by a quantum rotor dressed by the excitations
of a many-body bath, can be used to describe an impurity rotating in a fluid or
solid environment. Here, we propose a coherent state ansatz in the co-rotating
frame, which provides a comprehensive theoretical description of angulons. We
reveal the quasiparticle properties, such as energies, quasiparticle weights,
and spectral functions, and show that our ansatz yields a persistent decrease
in the impurity’s rotational constant due to many-body dressing, which is consistent
with experimental observations. From our study, a picture of the angulon emerges
as an effective spin interacting with a magnetic field that is self-consistently
generated by the molecule’s rotation. Moreover, we discuss rotational spectroscopy,
which focuses on the response of rotating molecules to a laser perturbation in
the linear response regime. Importantly, we take into account initial-state interactions
that have been neglected in prior studies and reveal their impact on the excitation
spectrum. To examine the angulon instability regime, we use a single-excitation
ansatz and obtain results consistent with experiments, in which a broadening of
spectral lines is observed while phonon wings remain highly suppressed due to
initial-state interactions.

text: Universal nonequilibrium properties of isolated quantum systems are typically
probed by studying transport of conserved quantities, such as charge or spin,
while transport of energy has received considerably less attention. Here, we study
infinite-temperature energy transport in the kinetically constrained PXP model
describing Rydberg atom quantum simulators. Our state-of-the-art numerical simulations,
including exact diagonalization and time-evolving block decimation methods, reveal
the existence of two distinct transport regimes. At moderate times, the energy-energy
correlation function displays periodic oscillations due to families of eigenstates
forming different su(2) representations hidden within the spectrum. These families
of eigenstates generalize the quantum many-body scarred states found in previous
works and leave an imprint on the infinite-temperature energy transport. At later
times, we observe a long-lived superdiffusive transport regime that we attribute
to the proximity of a nearby integrable point. While generic strong deformations
of the PXP model indeed restore diffusive transport, adding a strong chemical
potential intriguingly gives rise to a well-converged superdiffusive exponent
z≈3/2. Our results suggest constrained models to be potential hosts of novel transport
regimes and call for developing an analytic understanding of their energy transport.

text: Gears and cogwheels are elemental components of machines. They restrain degrees
of freedom and channel power into a specified motion. Building and powering small-scale
cogwheels are key steps toward feasible micro and nanomachinery. Assembly, energy
injection, and control are, however, a challenge at the microscale. In contrast
with passive gears, whose function is to transmit torques from one to another,
interlocking and untethered active gears have the potential to unveil dynamics
and functions untapped by externally driven mechanisms. Here, it is shown the
assembly and control of a family of self-spinning cogwheels with varying teeth
numbers and study the interlocking of multiple cogwheels. The teeth are formed
by colloidal microswimmers that power the structure. The cogwheels are autonomous
and active, showing persistent rotation. Leveraging the angular momentum of optical
vortices, we control the direction of rotation of the cogwheels. The pairs of
interlocking and active cogwheels that roll over each other in a random walk and
have curvature-dependent mobility are studied. This behavior is leveraged to self-position
parts and program microbots, demonstrating the ability to pick up, direct, and
release a load. The work constitutes a step toward autonomous machinery with external
control as well as (re)programmable microbots and matter.
