Summary: Using atomically thin superconductor platform on Si(111) with controlled nanohole defects, the study reveals the impact of defect density and geometric arrangements on superconductivity at different length scales. It was found that at certain defect density, the superfluid density can completely disappear, indicating a collapse in superconductivity.

Summary: We present the first nonlinear lattice simulation of the axion field coupled to a U(1) gauge field during inflation, and use it to fully characterize the statistics of the primordial curvature perturbation ζ. We find that high-order statistics are crucial in describing the non-Gaussianity of ζ in the linear regime of the theory, but non-Gaussianity is suppressed in the nonlinear dynamics. This relaxation of bounds allows for an observable gravitational wave signal at pulsar timing array and interferometer scales. Our work establishes lattice simulations as a crucial tool in studying the inflationary epoch and its predictions.

Summary: We find that the presence of both an orbital magnetic field and disorder in a two-dimensional type-II s-wave superconductor leads to an intriguing evolution. As the disorder increases, the critical field for the collapse of superfluid density diverges from the field at which the superconducting energy gap is suppressed, creating a pseudogap region with insulating vortex cores. Our findings provide a natural explanation for the observed gigantic magnetoresistance peak in disordered superconducting films and the disappearance of the celebrated zero-bias Caroli-de Gennes-Matricon peak in the local density of states at vortex cores in disordered superconductors.

Summary: Quantum spin liquids are exotic states of matter that form under strong frustrated magnetic interactions, with interconnected spin-1 trillium lattices exhibiting a significantly elevated level of geometrical frustration. Experimental and computational analysis showed a highly correlated and dynamic three-dimensional network structure with characteristics resembling a quantum spin liquid state under specific conditions.

Summary: In this study, we built a precisely characterized quantum simulator using cQED tools and successfully measured the finite frequency linear response of a non-trivial bosonic impurity problem. The experimental results quantitatively matched a perturbative calculation based on a microscopically calibrated model and revealed another many-body broadening phenomenon. Furthermore, we extended the usage range of the device and called for more advanced theoretical tools to model many-body quantum circuits. This work opens exciting perspectives for quantifying quantum entanglement near quantum critical points or accessing the dynamical properties of non-trivial many-body problems.

Summary: The non-ergodic extended (NEE) regime has garnered attention in the study of physical and random matrix models. By using singular-value-decomposition (SVD) to analyze the eigenvalue spectra of these models, a super-Poissonian behavior is observed, revealing the minibands structure of the NEE regime. This study applies SVD to various random matrix models, qualitatively demonstrating the NEE regime and quantitatively determining the ergodic-NEE transition point. The NEE regime is further discovered in a new type of random matrix model, the sparse RM model.

Summary: In this study, the work statistics for quantum phase transition were systematically investigated. Different regimes were identified for different quench rates, reflecting the competition between frozen time and quench timescale. Universal scaling behaviors in work statistics were found in each regime, with critical exponents determined by various factors including space-time dimension, dynamical critical exponent, and power-law protocols. These universal scalings in nonequilibrium processes may be observed in quantum phase transition through measuring the Loschmidt echo or the Ramsey interferometry.

Summary: An intense debate has arisen recently regarding the changes induced by light in iron-chalcogenide superconductors, specifically the enhancement of superconductivity and the emergence of a metastable state. Through high-energy resolution techniques, we directly observe the melting of superconductivity on ultrafast timescales. Our results demonstrate a non-equilibrium response on short timescales, with the gap filling in before the destruction of the superconducting peak, followed by a metastable response. We propose that pair phase decoherence and an increase in double-stripe correlations competing with superconductivity could explain these observations. These findings contribute to the exciting advancements in iron-based superconductors and suggest that the photoinduced metastable state may compete with superconductivity.

Summary: Experimental measurement of density fluctuations across the superfluid-supersolid phase transition provides insight into the static structure factor, spectrum of elementary excitations, and dominant fluctuation patterns. Strong response in static structure factor and presence of a distinct roton minimum in the dispersion relation suggest the presence of roton modes at the quantum critical point in the supersolid state. The study also indicates that the supersolid state supports both superfluid and crystal phonons.

Summary: This study numerically investigates the stability of a discrete time crystal against thermal fluctuations. It reveals that while the long-range temporal crystalline order is stable at low temperature, it melts and undergoes a non-equilibrium phase transition above a critical temperature. The critical properties of the continuous phase transition are systematically studied and found to fall into the same universality class as the kinetic Ising model without driving, despite the genuine nonequilibrium feature of the periodically driven system.

Summary: The study reveals a spin-fluctuation-driven charge loop current (cLC) mechanism in a simple frustrated chain Hubbard model, leading to the ferro-cLC order between the antiferromagnetic and d-wave superconducting (dSC) phases. The transition temperature T-cLC of cLC can be higher than that of dSC in a wide parameter range. The ferro-cLC order is driven by the enhancement of forward scatterings g(2) and g(4) due to the two dimensionality in metals near the magnetic criticality with geometrical frustration.

Summary: We investigate the effects of logarithmic perturbations of reaction rates on chemical reaction networks driven far from equilibrium. Our findings show that the response of the average number of chemical species is limited by both number fluctuations and the maximum thermodynamic driving force. We provide evidence for these trade-offs in linear chemical reaction networks and a specific class of nonlinear chemical reaction networks with a single chemical species. Numerical results from various model systems suggest that these trade-offs hold for a wide range of chemical reaction networks, although their specific form seems to depend on the network's deficiency.

Summary: Living organisms benefit from molecular sensitivity in key processes like DNA replication and chemical sensing. A simple structural quantity, the size of perturbation support, limits the sensitivity of biological processes, whether at or away from thermodynamic equilibrium. A novel non-equilibrium binding mechanism, nested hysteresis, with exponential sensitivity relative to the number of binding sites, has been discovered.

Summary: We analyze the static response to perturbations of nonequilibrium steady states modeled as one-dimensional diffusions on the circle. We demonstrate that arbitrary perturbations can be decomposed into combinations of three specific classes of perturbations that can be effectively addressed individually. For each class, we derive simple formulas that quantitatively characterize the response in terms of the strength of nonequilibrium driving, valid even far from equilibrium.

Summary: Near equilibrium, Green-Kubo relations provide microscopic expressions for macroscopic transport coefficients based on equilibrium correlation functions. This paper explores the relationship between response and fluctuations far from equilibrium, predicting how spatial inhomogeneities in macroscopic nonequilibrium systems relax. By deriving nonequilibrium Green-Kubo relations, the study establishes transport coefficients for density and phase diffusion, providing a theoretical foundation for Onsager's regression hypothesis.
