This study utilizes magneto-Raman scattering to reveal how magnetic field tuning and layer thickness modulate the complex magnetic phase diagram and spin-lattice coupling in two-dimensional chromium oxychloride (CrOCl), identifying commensurate magnetic orders and significant magneto-strictive effects down to the single-layer limit.
This paper provides a microscopic explanation for the unconventional out-of-plane spin polarization in -wave antialtermagnets by linking it to a site-compensated spin density, a mechanism verified through model derivation and *ab initio* calculations on CeNiAsO, while offering a general framework to distinguish between different magnetic orders and guide the design of materials with large spin splitting.
This study demonstrates a gate-tunable and highly anisotropic Josephson diode effect in topological Dirac semimetal CdAs nanowire junctions, utilizing a phenomenological model and temperature-dependent measurements to disentangle bulk and surface state contributions and reveal the coexistence of multiple transport channels as a probe for hidden topological superconducting states.
This study utilizes first-principles calculations and a coupled-Dirac-cone model to demonstrate that the topological nature and magneto-optical response of five-septuple-layer MnBiTe films are tunable and can switch between topological and trivial states depending on the relative spin orientations of the surface layers.
This paper investigates the orbital-Zeeman cross correlation in altermagnets, revealing that while -wave order parameters have limited or magnitude-reducing effects on Rashba metals and topological insulator surfaces, -wave order parameters induce a sign change in Rashba metals and preserve the chemical potential jump magnitude in topological insulators while reducing the overall term.
Using scanning tunneling microscopy and tight-binding calculations, this study reveals how strain induces distinct domain wall transitions and modulates electronic states in marginally twisted bilayer graphene, establishing strain as a key control parameter for its structural and electronic properties.
This paper reviews and clarifies the validity of Pfaffian-based topological invariants in one-dimensional semiconductor-superconductor nanowires by demonstrating their equivalence across momentum-space, real-space, and disordered systems, while establishing a direct physical interpretation linking the invariant to ground-state fermion parity.
This paper introduces a novel tensor-network methodology that combines real-space Bethe-Salpeter Hamiltonian encoding with a Chebyshev algorithm to efficiently compute excitonic spectra and bound-exciton spectral functions in super-moiré systems exceeding one billion lattice sites, thereby overcoming the computational limitations of conventional approaches for large-scale quantum matter.
This paper demonstrates a highly coherent singlet-triplet hole spin qubit in germanium that achieves high-fidelity universal control and a tenfold increase in coherence time via resonant driving at low magnetic fields and low exchange interaction, effectively overcoming the trade-off between gate speed and charge noise sensitivity.
This paper presents a Lindblad-based framework for analyzing slowly driven many-qubit thermal machines, demonstrating that geometric heat pumping can surpass the non-interacting Landauer-like bound through qubit interactions and asymmetric bath couplings, thereby offering a pathway to optimize the performance of driven quantum heat engines.
This paper proposes an approximate mapping of molecular Hamiltonians to a system-bath model, where a two-orbital active space is encoded by two qubits and the remaining electronic excitations are modeled as a bosonic bath, enabling high-accuracy calculations of vertical excitation energies on near-term quantum computers.
This paper investigates the quantum dynamics of two repulsively interacting particles confined to a helix, revealing how the helix's geometry creates a tunable multi-well potential that governs complex wave packet scattering patterns, including beats and pulsed emissions.
This paper demonstrates that circularly polarized light can induce spin polarization in an achiral metalloporphyrin complex by selectively exciting ring currents to break spin degeneracy, with the resulting transient polarization depending on spin-orbit coupling and Jahn-Teller dephasing rates.
This study demonstrates that in the van der Waals magnet Fe5GeTe2, strong electronic correlations drive the formation of a flat band at the Fermi level, which in turn induces a charge order, establishing a paradigm where interaction-driven flat bands promote large-scale electronic ordering.
This study demonstrates that growing tensile-strained ultrathin Yttrium Iron Garnet (YIG) films on Gadolinium Scandium Gallium Garnet (GSGG) substrates suppresses interfacial interdiffusion through enhanced chemical stability, thereby achieving ultralow damping and tunable magnetic anisotropy at cryogenic temperatures essential for advanced spintronic applications.
This paper theoretically demonstrates that the interplay between electron-magnon scattering and spin-orbit-induced electron-electron scattering drives ultrafast demagnetization in itinerant ferromagnets by simultaneously generating magnons and transferring angular momentum to the lattice in a non-equilibrium microscopic scenario.

This paper demonstrates that in planar magnetic multilayers without Dzyaloshinskii-Moriya interaction, interlayer exchange interactions, rather than dipolar effects, are the dominant mechanism driving the frequency shift of nonreciprocal spin-wave dispersion when counterpropagating modes exhibit distinct geometric structures along the thickness.
This paper derives a novel theoretical expression for the relaxation time of interacting magnetic nanoparticles by extending Kramers' theory with Tsallis statistics, providing a unified framework that explains both the decrease and increase of relaxation time with dipolar coupling and offers a new interpretation of glassy freezing dynamics through a cut-off temperature.
