This study demonstrates that exchange hierarchy and lattice distortion in the distorted kagome magnet drive emergent dimensional reduction, reorganizing the system into weakly coupled spin chains that suppress three-dimensional magnetic order and stabilize a robust quantum-disordered state down to ultralow temperatures.
Using microscopic-area angle-resolved photoemission to overcome surface termination challenges, this study reveals a dichotomy in electron-phonon interactions within PdCoO, characterized by weak coupling in the bulk and at CoO-terminated surfaces, but surprisingly strong polaronic coupling at the metallic Pd-terminated surface.
This paper demonstrates that spiral magnets enable the precise, topologically protected positioning of bimerons via a rotating magnetic field, which displaces them by exactly one spiral period per rotation, offering a low-power alternative to traditional pinning-based racetrack memory.
This paper presents a quantum transport theory coupling nonequilibrium electron-hole dynamics with classical magnetic moment evolution to explain how femtosecond laser pulses excite magnons in 2D antiferromagnetic semiconductors via spin-transfer torque from unbound carriers and excitons, ultimately predicting that these magnons can pump detectable charge currents as a novel experimental signature.
This study reveals a rich phase diagram in semimetallic rhombohedral hexalayer graphene, characterized by electric-field-driven band inversion, dual-carrier superconducting-like states, and a novel ferroelectric orbital magnetism that exhibits sharp, reversible magnetic switching under unipolar electric fields.
This paper demonstrates that noninteracting -state Fock parafermions on a one-dimensional lattice can be mapped to simpler -state parafermions (or fermions when is a power of two), enabling the construction of solvable parafermionic Hamiltonians with single-particle spectra identical to their fermionic counterparts.
This paper proposes a scalable method to extract transport coefficients, such as the Hall response, in gapped quantum systems by reconstructing them from local static ground-state currents measured in quantum simulators, thereby bypassing the need for external forcing and time-resolved measurements.
This paper calculates the anomalous Hall conductivity in rhombohedral stacked multilayer graphene using the Kubo-Streda approach, accounting for various impurity scattering mechanisms and band warping effects to explain the experimentally observed spontaneous spin-valley polarized quarter metal state.
Using terahertz spacetime metrology, the study reveals that the Drude weight in mono- and bi-layer graphene exceeds non-interacting predictions due to many-body interactions coupled with the Dirac fermions' pseudospin wave function structure, demonstrating how single-particle electronic properties directly influence collective excitations in quantum materials.
By combining inelastic scattering experiments with *ab initio* calculations, the study reveals that an anomalous softening of a specific oxygen phonon mode in LaCoO provides momentum-resolved evidence for dynamic correlations between high-spin and low-spin Co states, directly linking spin-state fluctuations to lattice dynamics.
This paper demonstrates that the low-temperature ferromagnet-to-paramagnet transition in the two-dimensional random-bond Ising model is controlled by a zero-temperature fixed point that can be understood via a renormalization group mapping to a noninteracting quantum problem exhibiting an infinite randomness fixed point, where the tunneling exponent equals the spin stiffness exponent.
This paper unifies the understanding of Strong Zero Modes (SZMs) by revealing their underlying commutant algebra structures, which not only demystifies their connection to ground state phases but also enables the construction of integrability-breaking models that preserve exact SZMs, while distinguishing between SZMs that survive such perturbations and those that do not.
First-principles calculations reveal that epitaxial strain induces distinct structural transitions in (111)-oriented (LaMnO)(SrMnO) superlattices, where the thickness-dependent response of oxygen octahedra tilt patterns ( vs. ) and the resulting interplay between charge, spin, and lattice distortions are particularly pronounced in the case under tensile strain.
This study demonstrates that bulk single crystals of the triplet superconductor uranium ditelluride (UTe) exhibit an intrinsic, electrically controllable memory effect where magnetic-field-tuned current pulses switch the material between metastable states of distinct critical currents, offering a promising pathway for ultralow-power superconducting memory in cryogenic computing.
Using a non-perturbative numerical approach, this study maps the finite-temperature phase diagram of a strongly correlated -wave altermagnet, revealing that altermagnetism-induced geometric frustration stabilizes a correlated magnetic metal and enhances magnetic transition scales across the Mott insulator-metal transition.
This study combines magnetization and dilatometry measurements with *ab initio* calculations to map the field-temperature phase diagram of the honeycomb magnet NaCoSbO, revealing strongly anisotropic magnetoelastic coupling driven by Co--O--Co bond angle variations and demonstrating that its field-induced transitions are first-order without evidence of a quantum spin liquid state.
This theoretical study establishes unconventional -wave magnets as a versatile platform for realizing a rich landscape of emergent superconducting phases, including topological superconductivity with Majorana edge modes, Bogoliubov Fermi surfaces, and the superconducting diode effect, within a unified microscopic framework.
This study demonstrates that quantum phase transitions significantly enhance the charging power of non-integrable quantum batteries based on the Axial Next-Nearest-Neighbor Ising model, contrasting with integrable cases where such effects are absent at short timescales and providing insights for the design of practical many-qubit energy storage devices.
This paper investigates mixed-state phases obtained by tracing out the bulk of higher-order subsystem SPTs protected by non-invertible Kramers-Wannier symmetries, revealing a "doubled average SPT" phase characterized by the coexistence of topological order and symmetry breaking that is diagnosed using interface probes.
This paper employs topological -group calculations for fiber bundles over tori, leveraging the index theorem of Dirac operators arising from spin-orbit interactions and time-reversal invariance, to mathematically explain the existence of gap-less conducting surface states in topological insulators.
