This study demonstrates that epitaxial growth of monolayer NbSe on graphite naturally forms moir{é} superlattices where interlayer coupling between graphite states and NbSe suppresses charge-density wave enhancement, offering a new pathway for controlling collective states in 2D materials without manual assembly.
By engineering the stacking configuration and twist angle of orthogonally-twisted CrSBr van der Waals magnets, researchers demonstrate a highly tunable magnetic hysteresis that enables on-demand switching between volatile and non-volatile memory states and controls abrupt spin-reversal processes, offering a new pathway for miniaturized spintronic devices.
Using strong-coupling time-dependent perturbation theory, this paper demonstrates that higher-harmonic currents in Mott-Hubbard and charge-transfer insulators encode information about spin order and microscopic hopping pathways, establishing them as effective probes for correlated materials and sensors for driving fields.
Using the traveling-solvent floating zone technique, high-quality single crystals of the distorted triangular lattice antiferromagnet CuLaGeO were successfully grown and characterized, revealing weak magnetic frustration, a low-temperature ordering transition at 1.14 K, and a unique noncollinear antiferromagnetic structure with an ordered moment of 0.89 lying in the bc-plane.
This study utilizes classical Monte Carlo simulations of an effective quadrupole model on a diamond lattice to demonstrate that the competition between magnetic fields and quadrupole anisotropy, mediated by a crucial symmetry-allowed biquadratic interaction, drives successive single- and double- ordering transitions that reproduce the experimentally observed weak-field topology in PrIrZn.
This paper investigates the algebraic structure of fuzzy sphere models for 3d CFTs by verifying the Jacobi identity of their density operators, analyzing their behavior in distinct thermodynamic limits, and constructing an explicit conformal algebra representation that reveals a structural mismatch with the thermodynamic limit of critical systems.
Inelastic neutron scattering on NaIrO reveals a 1.7 meV magnon gap and antiferromagnetic Heisenberg interactions, distinguishing its magnetic excitations from those in the sister compound -RuCl and demonstrating that low-energy ferromagnetic fluctuations are not a universal fingerprint of Kitaev physics.
This study utilizes spectroscopic ellipsometry to reveal that the metal-insulator transition in bulk $1T_2$ is a three-dimensional, interlayer-driven percolation process involving evolving metallic domain shapes and an intermediate phase, while also establishing the material as a tunable natural type-II hyperbolic medium.
This paper analyzes the nodal structure of bound-state wave functions in one-dimensional quantum systems with quartic dispersion, demonstrating that while the classical oscillation theorem holds in classically allowed regions, it breaks down in forbidden regions where wave functions exhibit additional nodes, a finding supported by semiclassical, variational, and exact solvable model approaches.
NMR Knight shift measurements on CeRhIn under pressure reveal that the suppression of the dipolar component at the In(1) site and the resulting pressure dependence of the shift are driven by an increase in 4f electron content at the Fermi surface, reflecting electronic structure changes near a Kondo breakdown quantum critical point.
This study demonstrates that applying uniaxial strain to hexagonal -MnTe detwins its magnetic domains, thereby enabling precise control over the anomalous Hall effect, including the ability to reverse its sign near room temperature, by modifying the electronic Berry curvature without altering the material's altermagnetic phase-transition temperature.
Using large-scale density matrix renormalization group simulations of the bosonic -- model, this study reveals six distinct quantum phases—including pair density waves and phase-separated ferromagnetic domains—arising from the competition between doped holes and antiferromagnetic order, while proposing a concrete experimental realization in Rydberg tweezer arrays to explore these intertwined orders relevant to high- superconductivity.
This study employs advanced numerical and theoretical techniques to reveal that while spin-$1/2S=1, 3/2$) generalizations of the Majumdar--Ghosh chain exhibit prominent magnon modes and a universal phenomenon of spinon confinement into bound states across first-order phase transitions, thereby establishing a unified quasiparticle framework for understanding excitations in frustrated quantum spin chains.
This paper provides two distinct derivations of the full nonlinear Schwarzian effective action governing the low-temperature soft mode of the large- SYK model and its chain generalization, demonstrating that these effective descriptions can be rigorously derived from microscopic dynamics without relying on additional assumptions or matching procedures.
This paper demonstrates that unconventional early-time relaxation dynamics in Rydberg atom chains, characterized by a specific decay rate of the survival probability, serve as a robust experimental signature for detecting quantum many-body scarring at time scales significantly shorter than thermalization.
This paper establishes a simple thermodynamic framework using ultrafast pump-probe measurements to demonstrate that the ultrafast insulator-to-metal transition in vanadium dioxide is driven by the population of the full thermal phonon spectrum, particularly high-frequency oxygen modes, rather than a single coherent structural mode.
This paper investigates (3+1)d topological orders with anomalous symmetry by microscopically constructing symmetry-preserving gapped boundary states for related (4+1)d SPT phases, demonstrating that such states admit a topological gauge theory description when , a non-TQFT solution when , and no symmetric gapped state otherwise, thereby confirming existing no-go theorems.
This study demonstrates that LaIrO is an orbital-selective spin-orbit Mott insulator where structural distortions and dimerization drive the bands to half-filling for correlation-driven Mott localization, while the bands remain band-insulating.
Through a soft topotactic reaction, researchers synthesized NiIrO3, the first honeycomb iridate with coupled 3d-5d magnetic sublattices, which exhibits a unique ferrimagnetic order and record-breaking magnetocrystalline anisotropy and coercivity driven by the synergistic effects of lattice frustration and strong spin-orbit coupling.
This study reports the synthesis and characterization of the 5f-electron kagome metal UCrGe, revealing its unique monoclinic supercell modulation, itinerant uranium behavior, and the presence of chromium-derived flatbands near the Fermi level, which collectively highlight the tunable magnetic ground states within the family.
