Using state-of-the-art matrix product state simulations, this study challenges the conventional view that the two nearly degenerate ground states of the spin-1/2 triangular-lattice - Heisenberg model represent distinct topological sectors of a gapped spin liquid, by demonstrating that they exhibit significant differences in both static correlations and dynamical excitations.
This study investigates the formation and stability of various quasi-one-dimensional solitons in self-repulsive spin-orbit-coupled dipolar Bose-Einstein condensates, revealing that the interplay between spin-orbit coupling strength and interaction parameters dictates the emergence of distinct soliton types (such as bright-bright, dark-bright, and their modulated variants) in both pseudo spin-half and spin-one systems, all of which are demonstrated to be dynamically stable.
This paper investigates the zero-temperature phase diagrams of two distinct families of bilayer antiferromagnets with SU(2) symmetry, revealing that while both exhibit first-order Néel-to-valence bond solid transitions, their topological differences—specifically the ability to exchange spin versus only energy—lead to the presence or absence of a dimer phase and distinct finite-size scaling behaviors.
This study reveals that filamentous *E. coli* induced by sub-lethal antibiotics exhibit distinct swimming behaviors in low-Reynolds number flows, where motile cells undergo a combination of rigid body rotation and chiral reorientation leading to irregular "wiggling" and wall-directed rheotaxis, while non-motile cells behave as passive rigid rods following streamlines.
This paper analyzes the non-equilibrium dynamics of the Ising model in one and two dimensions using a virtual walk approach associated with spin states and local energy, demonstrating that finite-time scaling of these walks yields critical exponents consistent with known theoretical values and reveals a distinct non-equilibrium region and time-dependent critical point.
This study demonstrates that oxygen isotope substitution () significantly increases the charge-density wave transition temperature in LaNiO while leaving the spin-density wave transition unaffected, indicating that lattice vibrations drive charge ordering whereas spin ordering is primarily electronic in origin.
This paper proposes a theoretical framework asserting that high-temperature superconductivity in cuprates and nickelates is driven by ionic-bond-mediated electron pairing bridged by oxygen or metal atoms, a mechanism supported by 32 experimental evidences and offering a potential path toward room-temperature superconductivity.
This study utilizes muon-spin rotation and resistivity measurements to reveal that in the trilayer nickelate LaNiO, pressure suppresses intertwined spin- and charge-density-wave transitions at a uniform rate while oxygen-isotope substitution selectively enhances the charge-density-wave transition, highlighting a distinct coupling between charge and spin orders that differs from bilayer nickelates.
This paper experimentally demonstrates the quantitative decomposition of heat dissipation into housekeeping and excess components in a non-equilibrium nanoscale dot with multi-electron states, revealing a direct correlation between these thermal processes and free-energy generation that achieves an efficiency of 0.25 under driven conditions.
This paper proposes a minimal model demonstrating that entropy maximization of spacers induces an attractive force between stickers, leading to sticker clustering and a slow, glassy relaxation process that explains the long-term aging and solidification of biomolecular condensates.
This paper provides a complete classification of symmetric and spin liquids on the pyrochlore lattice within the projective symmetry group framework, identifying novel classes with gapless "nodal star" spinon structures that exhibit distinct low-temperature specific heat scaling compared to standard quantum spin ice.
This paper investigates the boundary critical behavior of the semi-infinite Gross-Neveu-Yukawa model by analyzing its phase diagram, identifying distinct universality classes under various unitary and conformal boundary conditions, and computing the associated boundary critical exponents to one-loop order.
This paper proposes and analyzes a simple mathematical model describing how active and passive particles connected by a linear spring exhibit distinct straight, circular, and slalom motions, with theoretical analysis confirming a bifurcation between straight and circular trajectories driven by the magnitude of self-propulsion.
This paper reformulates the stability of flat-band Bose-Einstein condensation as a Euclidean geometry problem using compact localized states, demonstrating that triangular frameworks with nonzero area support condensation while square frameworks do not, thereby offering new design principles for stable flat-band condensates.
This paper introduces the MASBot robotic platform to experimentally demonstrate a unified phase diagram of nonreciprocal active matter, revealing continuous transitions between odd elastic, odd viscous, and chiral active gas phases while establishing a blueprint for programmable robotic swarms.
This paper employs Monte Carlo simulations of a U(1) lattice gauge system to demonstrate that the thermal phase transition of a superconductor belongs to the XY universality class, exhibiting critical exponents consistent with Bose-Einstein condensation and neutral boson transitions.
This paper derives a non-equilibrium generalized Langevin equation for multi-dimensional observables using the Mori-Zwanzig formalism, revealing a unique instantaneous friction contribution that vanishes only for uncorrelated components, and demonstrates its application to modeling coupled protein folding kinetics in human islet amyloid polypeptide fibril formation.
This paper extends the theoretical framework for estimating diffusive flux into stochastically gated tubes by deriving an explicit formula that remains accurate for non-narrow geometries and varying diffusivities, overcoming challenges related to complex 3D geometry and multiplicative noise.
This study utilizes molecular dynamics simulations to demonstrate that the capillary filling dynamics and post-imbibition relaxation of star polymer melts are profoundly governed by their topology, where arm length and functionality dictate deviations from the Lucas-Washburn equation, induce arm orientation and disentanglement, and significantly enhance adsorption and friction effects.
This paper proposes and numerically validates an experimentally feasible protocol for the deterministic nucleation and manipulation of stable quantum vortex rings in Bose-Einstein condensates using a sweeping laser-sheet barrier, enabling precise control over their properties and the generation of Kelvin-wave excitations for the study of three-dimensional vortices and quantum turbulence.
