Summary: Chemically driven fluids can separate into condensed droplets under non-equilibrium conditions, and the differential driving between the interior and exterior of the droplets leads to nonequilibrium interfacial properties. The study shows that the nonequilibrium interfacial tension can either increase or decrease compared to its equilibrium value, depending on the acceleration or deceleration of chemical reactions within the droplets.

Summary: By resonantly shaking the pump field in an atom-cavity system, a periodically driven open three-level Dicke model was realized, showing the emergence of a dynamical phase where atoms periodically localize between the antinodes of the pump lattice. This dynamical phase was observed through the periodic switching of relative phase between the pump and cavity fields at a small fraction of the driving frequency, suggesting a time crystalline character.

Summary: This study explores a nonequilibrium extension of the 2D XY model, equivalent to the noisy Kuramoto model of synchronization with short-range coupling, finding that nonequilibrium drive disrupts the quasi-long-range ordered phase, leading to a mosaic of ordered domains and self-propelled vortices with superdiffusion characteristics.

Summary: We investigate the correlation functions of a class of periodically driven integrable closed quantum systems and find that they approach their steady-state value as the number of drive cycles increases. The behavior of these correlation functions can undergo transitions at specific drive frequencies or phase boundaries, which are determined by the symmetries of the Floquet spectrum.

Summary: The wetting transition of the spin-1/2 XY model with opposite boundary fields is studied analytically and numerically. Three types of wetting transitions are observed and the phase diagram is found to be complex. The results obtained include the energy gap, magnetization profile, correlation functions, and wetting layer thickness. The wetting behavior is induced by asymmetric boundary fields and its finite-size scaling is discussed. The fourth-order wetting transition belongs to a new universality class with oscillations and divergences in the third derivative of the surface magnetization near the transition point.

Summary: We studied the stroboscopic dynamics of a periodically driven finite Rydberg chain with staggered and time-dependent detuning terms. It was found that at intermediate drive frequencies, the finite size of the chain leads to violation of the eigenstate thermalization hypothesis (ETH) through clustering of Floquet eigenstates. The violation of ETH is also observed in the freezing of density-density correlations between Rydberg excitations at even sites for specific drive frequencies. We also investigated the existence of quantum many-body scars in the Floquet spectrum and found mid-spectrum scars that do not overlap with specific initial states.

Summary: We propose a superconductor-normal metal-superconductor (SNS) junction where Josephson diode effect manifests when the normal metal region is driven. Time reversal symmetry and inversion symmetry need to be broken in the SNS junction for the diode effect to show up. We calculate long time averaged current and show that the system exhibits diode effect for two configurations of the driven SNS junction.

Summary: Vacancies play a crucial role in the topological transition of transition metal dichalcogenides, inducing a topologically nontrivial phase. Vacancy states in PtSe2 result in a large topological gap within the pristine system gap, allowing the construction of backscattering protected metallic channels embedded in a semiconducting host.

Summary: By analyzing the geometric phase and thermodynamic length in the transport process and the energy conversion process of driven nonequilibrium quantum systems, this review provides a unified perspective for recent research. The discussion over thermodynamic geometry yields multiple constraints on transport and energy conversion, leading to a general optimization method. This will contribute to a better understanding of functionality for nonequilibrium quantum many-body systems acting as thermal machines.

Summary: In this study, the quantum renormalization group (QRG) method is applied to investigate the relationship between entanglement and quantum phase transition in the spin-1/2 XY chain. Tripartite negativity and bipartite negativity are used as measurements of entanglement, and their first derivatives and scaling behaviors are examined. The results demonstrate that the evolutions of tripartite and bipartite negativity can reveal the unstable fixed point (critical point) and the stable fixed point, which are verified by the first derivatives in the thermodynamic limit. Additionally, the first derivatives of tripartite and bipartite negativity exhibit singular behaviors, indicating the occurrence of second-order phase transition. The renormalized tripartite negativity and bipartite negativity follow the same scaling laws near the quantum phase transition point. These findings suggest that the QRG implementation of negativity can serve as another description of critical behavior in the XY model.

Summary: This study investigates the phase diagram and dynamic critical behaviors of the one-dimensional anisotropic XY model with ferromagnetic and antiferromagnetic interactions. By employing the quantum renormalization-group method, three phases were identified in the system, with concurrence oscillating periodically over time in two quantum quenching methods. The findings suggest a scaling behavior for the evolution period and a reciprocal relation between the evolution period exponent theta and correlation length exponent nu.

Summary: In this work, we propose a scheme to simulate Kitaev's honeycomb model with cold atoms using a periodic (Floquet) drive, aiming to realize and probe non-Abelian chiral spin liquids. We derive the effective Hamiltonian and show that the drive can open a topological gap in the spectrum without mixing the effective Majorana and vortex degrees of freedom. We address the challenge of probing Majorana fermions while only having access to the original composite spin degrees of freedom. Specifically, we propose using gap spectroscopy and edge quenches to detect the properties of the chiral spin liquid phase in the presence of the Floquet drive, and find that the resulting chiral edge signal is robust for realistically prepared states. By combining strong interactions with Floquet engineering, our work paves the way for future studies of non-Abelian excitations and quantized thermal transport using quantum simulators.

Summary: This paper proposes a scheme to realize Floquet higher-order topological insulator (HOTI) with ultracold atoms in optical lattices, and successfully constructs a Floquet second-order topological insulator with special bulk-edge correspondence. It also exhibits other intriguing topological phenomena. The scheme is of great significance for studying the relations between different types of topological states and constructing higher-order topological insulators in synthetic systems.

Summary: In this study, the quantum criticality and critical exponents variation in the spin-1/2 anisotropic XY chain with staggered Dzyaloshinskii-Moriya interaction were investigated using the infinite time evolving block decimation method in infinite matrix product state representation. The phase diagram was obtained from entanglement measurement, revealing continuous variation of critical exponents along the critical line and the ratios of critical exponents implying weak universality. The linear relationships of critical exponents illustrate the dependence between critical exponents and the Dzyaloshinskii-Moriya interaction.

Summary: Significant progress has been made in the theoretical understanding of transport properties in one-dimensional quantum lattice systems in the past decade, with Bethe-ansatz integrable models and novel simulation methods playing important roles. The discovery of quasilocal conserved quantities provides insight into the origins of finite-temperature transport behavior, while state-of-the-art theoretical methods, including matrix-product-state-based simulation and generalized hydrodynamics, are discussed. The close connection between theoretical models and recent experiments, particularly in the context of quantum magnets and ultracold quantum gases in optical lattices, is also highlighted.

Summary: We propose and discuss two variants of cellular automata models that describe the behavior of particles in 1 + 1 dimensions. The first model describes two types of quasiparticles, while the second model represents a quantum deformation of a previously studied lattice gas model. Both models exhibit intriguing properties and may have potential applications in further research.
