This study reveals that a high-entropy antiferromagnet, (Mn1/4Fe1/4Co1/4Ni1/4)PS3, sustains long-range zigzag magnetic order below 72 K despite significant atomic disorder, where all four transition-metal elements undergo a unified phase transition but maintain distinct spin orientations due to the competition between single-ion anisotropies and exchange interactions.
This paper demonstrates that within the Unified Nonequilibrium Perturbative framework, the anyonic exchange phase in Fractional Quantum Hall edges is fundamentally tied to Luttinger liquid scaling dimensions, yielding unique solutions for both Poissonian and super-Poissonian DC backscattering currents and noise through a derived nonequilibrium fluctuation-dissipation relation.
This paper proposes robust protocols using spatially local anyon injection at a single quantum point contact to isolate the universal anyonic statistical phase from nonuniversal interaction effects, deriving novel fluctuation-dissipation relations that allow for the direct experimental measurement of this phase via AC admittance or DC noise.
This paper theoretically demonstrates that a non-zero magnon thermal Hall effect can occur in collinear antiferromagnets at zero external magnetic field, driven by symmetry-breaking mechanisms such as sublattice asymmetry in compensated Néel order or Dzyaloshinskii-Moriya interactions in weak ferromagnets, and proposes a model where an external electric field can modulate this effect by altering the system's symmetry.
This paper establishes a general framework for intrinsic nonlinear thermal conductivity in bosonic systems using a quantum kinetic equation approach that naturally incorporates energy magnetization, identifying quantum-geometric contributions like thermal Berry-connection polarizability (TBCP) that dominate nonlinear thermal Hall effects and differ quantitatively from semiclassical predictions.
This paper extends the microscopic calculation of shear viscosity in graphene electron fluids to finite magnetic fields using kinetic theory, revealing that the magnetic field induces anisotropy resulting in five independent viscosity coefficients, with significant suppression of perpendicular and parallel components and maximized Hall effects occurring at specific field strengths that vary across non-relativistic, relativistic graphene, and ultra-relativistic quark fluid systems.
This paper employs the hierarchy of correlations and strong-coupling perturbation theory to demonstrate that while charge disorder induces an energetic and spatial separation between localized and delocalized doublon and holon excitations in the Mott-Hubbard model, spin disorder leads to the localization of states throughout the entire quasi-particle band.
This study demonstrates that high-energy electron irradiation can shift the Fermi level of the half-Heusler Weyl semimetal GdPtBi by 100 meV while preserving the negative longitudinal magnetoresistance indicative of chiral magnetic anomaly, thereby confirming the robust influence of Weyl nodes on magnetotransport properties regardless of Fermi level position.
This study demonstrates that the half-Heusler topological semimetal DyPtBi simultaneously exhibits large longitudinal and transverse magnetothermopowers at practical temperatures and magnetic fields, overcoming the conventional trade-off through an ambipolar effect driven by imperfect electron-hole compensation and band structure engineering.
This study employs self-consistent Hartree-Fock calculations to demonstrate that proximity-induced spin-orbit coupling from a transition-metal dichalcogenide layer critically tunes the spin nature and symmetry-breaking patterns of correlated ground states in twisted mono-bilayer graphene, driving transitions between various magnetic orders and inducing chiral non-coplanar states depending on the specific type and combination of Rashba and Ising coupling.
This paper proposes a quantum simulation scheme using ultracold atoms in optical lattices to realize the three-band Emery model, enabling the study of high-temperature superconductivity in cuprates and nickelates on system sizes that are currently inaccessible to numerical methods.
This study demonstrates the first observation of robust, coherent non-Abelian hadron dynamics on a noisy 156-qubit quantum processor by simulating a 60-site SU(2) lattice gauge theory using a hardware-efficient encoding, successfully capturing meson propagation and breathing modes while outperforming classical approximation methods in the weak-coupling regime.
This paper analyzes the classical Kitaev honeycomb model in a magnetic field, revealing a finite-field spin liquid regime characterized by short-range correlations, specific thermodynamic constraints, and a unique "perfect" compensation of weak site-dilution effects on magnetization.
Motivated by recent twisted MoTe experiments, this paper develops a disordered interacting edge theory for a fractional topological insulator, revealing distinct conductance phases and an interaction-induced insulating state that demonstrates the insufficiency of two-terminal transport measurements for identifying such systems.
This paper derives the exact dual Ginzburg-Landau theory for a minimal holographic superconductor at finite coupling, revealing that the GL parameter increases (making the system more Type-II) and the condensate rises, while correcting previous misconceptions regarding the AdS/CFT dictionary and condensate determination.
By combining perturbative renormalization group analysis with large-scale matrix-product state simulations, this study demonstrates that quantum phase transitions in coupled Ising chains and SO()-symmetric spin systems are continuous for and but become first-order for , thereby refining conjectures about criticality in symmetry-protected topological phase transitions.
This study utilizes angle-resolved photoemission spectroscopy and cluster perturbation theory to demonstrate that the shallow electron pocket (-band) in CoTaS originates from correlation-driven bulk states requiring long-range Co ordering, rather than surface effects or standard DFT+U predictions.
This paper proposes that finding a Hamiltonian path on a two-dimensional lattice that minimizes a specific geometric cost function yields an optimal site numbering for the Density Matrix Renormalization Group (DMRG) algorithm, thereby significantly improving its accuracy and convergence speed for various spin models.
This paper develops a microscopic formalism to demonstrate how impurity-enabled electron-phonon coupling generates hybridized, massless nemato-elastic collective modes near a nematic quantum critical point, revealing a complex landscape of underdamped and overdamped dynamics with significant implications for nematic-fluctuation-mediated superconductivity.
This paper establishes that the paramagnon-interference mechanism drives the emergence of a commensurate 3D $2\times 2\times 2_3_5$, with the specific stacking pattern determined by the third-order Ginzburg-Landau term and the quasi-2D nature of the Fermi surface.
