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 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 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 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 proposes a higher-harmonic acoustic driving scheme that enables high-fidelity control of quantum-dot optical transitions at accessible acoustic frequencies (e.g., 42 GHz) despite large energy splittings (0.341 THz), thereby overcoming previous sub-THz limitations and paving the way for advanced on-chip quantum technologies involving multi-phonon processes and entanglement.
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 theoretically demonstrates that locally injected electric currents in chiral metals induce bulk spin polarization in the linear response and interface antiparallel spin polarization in the quadratic response, with the latter's sign being determined by dipole-like charge distributions rather than bulk spin currents, thereby reproducing experimental correlations between structural chirality and spin polarization direction.
This paper presents a finite-element method model capable of accurately simulating electrostatic patch forces in complex, realistic experimental geometries—including those with roughness, edges, and curvature—by utilizing Voronoi diagrams or Kelvin Probe Force Microscopy data to provide reliable estimates of parasitic forces relevant to Casimir force measurements and gravitational wave interferometers.
This paper demonstrates that near-field thermal transport in nanoparticles can be dynamically modulated through selective surface mode excitation by tuning the distance between reflectors and nanoparticles within a multilayer cavity, offering a novel mechanism for nanoscale thermal management and sensing.
This paper investigates a novel interedge backscattering mechanism in time-reversal symmetric quantum spin Hall Josephson junctions, where phase-independent Andreev bound states mediate coupling between opposite edges to open gaps and decouple a 4-periodic spectrum, leading to distinct signatures in Shapiro experiments and superconducting quantum interference patterns that can be tuned by magnetic flux.
