This paper investigates the Anderson localization of the disordered Hatano-Nelson chain, revealing a critical disorder threshold where the complex eigenvalue spectrum bifurcates and the spectral winding number transitions from 1 to 0, accompanied by a shift from exponentially localized states to two completely delocalized states at weak and critical disorder.
This paper presents a theoretical framework demonstrating that wall friction significantly alters the quasistatic mechanical response of confined poroelastic media by introducing hysteresis, slip fronts, and energy dissipation mechanisms that depend on whether the system is driven by piston loading or fluid pressure.
This paper reports the discovery of ambient-pressure superconductivity with an onset temperature of approximately 63 K in compressively strained (La,Pr)₃Ni₂O₇ thin films, achieved via a giant-oxidative atomic-layer-by-layer epitaxy method that enhances interlayer coupling and links the high transition temperature to strange-metal behavior.
This paper presents an exact solution for the ground states of the Ising model with three-spin interactions on a triangular ladder at fixed magnetization by reformulating the problem as a linear program, revealing a phase diagram that includes periodic, phase-separated, and ordered aperiodic states, while showing that treating magnetization as a free parameter restricts the ground states to specific periodic configurations.
This paper presents a generalized Langevin framework to model the averaged velocity modulus of self-propelled spherical and disk-shaped Brownian particles in a harmonic potential, revealing that while an internal Ornstein-Uhlenbeck mechanism induces spontaneous velocity fluctuations, these effects diminish over time as the system evolves.
This paper establishes a rigorous mathematical framework for hybrid classical-quantum systems by deriving their microcanonical ensemble via a maximum entropy principle, demonstrating its well-defined nature for continuous energy values and its consistency with the canonical ensemble, while validating the theory through a toy model.
This paper investigates the nonlinear breakup dynamics of an active chiral fluid strip, demonstrating through analytical slender body theory and numerical simulations that its thickness vanishes as a power law in finite time, with results showing strong agreement with experimental observations.
Using molecular dynamics simulations, this study demonstrates that the collapse of extended polymers exhibits scale-free cluster-cluster aggregation with universal dynamic scaling, where the growth exponent remains constant () across varying bending stiffness, while deviations from standard diffusion-controlled relations in stiffer polymers arise from stiffness-dependent variations in cluster structure and effective diffusion.
Using large-scale quantum Monte Carlo simulations, this study reveals that infinite-range light-matter interactions in frustrated Rydberg atom triangular arrays lift ground-state degeneracy to induce a novel superradiant clock phase, replacing fragile classical order-by-disorder with a first-order transition driven by nonzero photon density and nonlocal ring exchange interactions.
This paper introduces a site-decorated Ising model that exactly maps to a frustrated bond-decorated system to explain ultranarrow phase crossovers and derive an exact solution for a temperature- or field-triggered spin-reversal transition, offering potential applications in energy-efficient devices and serving as a validated testbed for AI-assisted scientific discovery.
This paper derives the exact solution for the three-dimensional Z2 lattice gauge theory by leveraging its duality with the 3D Ising model, while investigating the roles of nonlocal effects, topological structures, and fundamental symmetries in these many-body systems.
This study reveals that the dimensionality of superconductivity in infinite-layer nickelates is extrinsically controlled by disorder, where low disorder yields a quasi-two-dimensional vortex state while increased disorder drives a crossover to a pure two-dimensional state due to the decoupling of NiO₂ planes.
This paper investigates the stability and excitation properties of topological states in moiré flat bands modeled as opposite-Chern Landau levels under external magnetic fields, revealing interaction-driven phase transitions and spin-flip instabilities along Streda lines while introducing a novel "center-of-charge" basis to exactly solve the two-body problem with unequal magnetic fields, thereby extending Haldane pseudopotentials to capture non-monotonic interaction structures.
This paper employs a tight-binding lattice model to investigate the gap structure and phase diagram of twisted bilayer cuprates, revealing that the time-reversal symmetry breaking state is correlated with the Van Hove singularity's position—which varies with doping and interlayer tunneling—and discussing how these findings reconcile conflicting experimental results.
Using the density-matrix renormalization group method, this study demonstrates that Emery ladders preserving the Cu-to-O ratio transition from charge-transfer insulators to Luther-Emery liquids with enhanced pairing upon doping, successfully reproducing the relationships between charge distribution, pairing strength, and interactions observed in both two-dimensional models and experiments.
This study demonstrates that epitaxial La2.82Sr0.18Ni2O7 thin films exhibit intrinsic three-dimensional bulk superconductivity with a sharp transition at 31.6 K, where the in-plane upper critical field is significantly suppressed by spin-paramagnetic pair breaking near the Pauli limit, resulting in a reduced anisotropy ratio of approximately 1.34.
This paper extends the multipole formalism from one-body to many-body operator spaces by utilizing spherical tensor fermionic operators and exterior algebra to systematically classify interacting systems, revealing that electric and magnetic toroidal monopoles emerge in spinless many-body systems despite being absent in single-particle hybrid orbital spaces.
This paper predicts that the room-temperature ferromagnetic half-metal Mn2PC monolayer hosts type-II Weyl-like states and a concurrent anomalous Hall effect, enabling giant topological tunneling magnetoresistance in magnetic tunnel junctions for potential spintronic applications.
Using scanning tunneling microscopy, researchers report the first experimental observation of a translational-symmetry-breaking Kondo hybridization wave on the surface of the heavy-fermion superconductor UTe2, revealing a new ordered phase that coexists with superconductivity and offers fresh insights into the material's unconventional pairing mechanism.
Through numerical simulations and a mean-field model, this study reveals that motile rods immersed in a sea of apolar rods undergo an antidiffusive instability to form flocks, a segregation process that paradoxically reduces global polar order and produces flock shapes dependent on the medium's rod aspect ratio.
