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: It may come as a surprise that a phenomenon as ubiquitous and prominent as
the transition from laminar to turbulent flow has resisted combined efforts by
physicists, engineers and mathematicians, and remained unresolved for almost one
and a half centuries. In recent years, various studies have proposed analogies
to directed percolation, a well-known universality class in statistical mechanics,
which describes a non-equilibrium phase transition from a fluctuating active phase
into an absorbing state. It is this unlikely relation between the multiscale,
high-dimensional dynamics that signify the transition process in virtually all
flows of practical relevance, and the arguably most basic non-equilibrium phase
transition, that so far has mainly been the subject of model studies, which I
review in this Perspective.

text: 'Lead halide perovskites enjoy a number of remarkable optoelectronic properties.
To explain their origin, it is necessary to study how electromagnetic fields interact
with these systems. We address this problem here by studying two classical quantities:
Faraday rotation and the complex refractive index in a paradigmatic perovskite
CH3NH3PbBr3 in a broad wavelength range. We find that the minimal coupling of
electromagnetic fields to the k⋅p Hamiltonian is insufficient to describe the
observed data even on the qualitative level. To amend this, we demonstrate that
there exists a relevant atomic-level coupling between electromagnetic fields and
the spin degree of freedom. This spin-electric coupling allows for quantitative
description of a number of previous as well as present experimental data. In particular,
we use it here to show that the Faraday effect in lead halide perovskites is dominated
by the Zeeman splitting of the energy levels and has a substantial beyond-Becquerel
contribution. Finally, we present general symmetry-based phenomenological arguments
that in the low-energy limit our effective model includes all basis coupling terms
to the electromagnetic field in the linear order.'

text: The self-assembly of nanoparticles driven by small molecules or ions may produce
colloidal superlattices with features and properties reminiscent of those of metals
or semiconductors. However, to what extent the properties of such supramolecular
crystals actually resemble those of atomic materials often remains unclear. Here,
we present coarse-grained molecular simulations explicitly demonstrating how a
behavior evocative of that of semiconductors may emerge in a colloidal superlattice.
As a case study, we focus on gold nanoparticles bearing positively charged groups
that self-assemble into FCC crystals via mediation by citrate counterions. In
silico ohmic experiments show how the dynamically diverse behavior of the ions
in different superlattice domains allows the opening of conductive ionic gates
above certain levels of applied electric fields. The observed binary conductive/nonconductive
behavior is reminiscent of that of conventional semiconductors, while, at a supramolecular
level, crossing the “band gap” requires a sufficient electrostatic stimulus to
break the intermolecular interactions and make ions diffuse throughout the superlattice’s
cavities.

text: The power factor of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)
(PEDOT:PSS) film can be significantly improved by optimizing the oxidation level
of the film in oxidation and reduction processes. However, precise control over
the oxidation and reduction effects in PEDOT:PSS remains a challenge, which greatly
sacrifices both S and σ. Here, we propose a two-step post-treatment using a mixture
of ethylene glycol (EG) and Arginine (Arg) and sulfuric acid (H2SO4) in sequence
to engineer high-performance PEDOT:PSS thermoelectric films. The high-polarity
EG dopant removes the excess non-ionized PSS and induces benzenoid-to-quinoid
conformational change in the PEDOT:PSS films. In particular, basic amino acid
Arg tunes the oxidation level of PEDOT:PSS and prevents the films from over-oxidation
during H2SO4 post-treatment, leading to increased S. The following H2SO4 post-treatment
further induces highly orientated lamellar stacking microstructures to increase
σ, yielding a maximum power factor of 170.6 μW m−1 K−2 at 460 K. Moreover, a novel
trigonal-shape thermoelectric device is designed and assembled by the as-prepared
PEDOT:PSS films in order to harvest heat via a vertical temperature gradient.
An output power density of 33 μW cm−2 is generated at a temperature difference
of 40 K, showing the potential application for low-grade wearable electronic devices.
