This paper proposes a Josephson junction architecture combining a -wave magnet and an altermagnet barrier to achieve a robust, field-free Josephson diode effect without requiring Rashba spin-orbit coupling or distinct superconductors, thereby offering a promising platform for quantum circuit applications.
This study employs a mixed quantum-classical approach to investigate how anharmonic nuclear potentials influence current-induced vibrational instabilities and junction dissociation probabilities in molecular nanojunctions, extending previous findings from harmonic models to more realistic systems.
This study demonstrates that quantum dots in monolayer transition-metal dichalcogenides exhibit significantly enhanced strain sensitivity compared to delocalized excitons due to strengthened interactions with low-energy phonons induced by quantum confinement, a finding that enables versatile strain-engineering for spectral matching in quantum photonic networks.
This paper theoretically investigates interfacial orbital transport in metals, revealing that crystal-field effects drive oscillatory transmission and conversion of orbital angular momentum into quadrupole moments while generating significant mechanical torque and finite dipole relaxation distinct from spin precession.
This paper demonstrates that silicon photonic crystal cavities operating at millimeter-wave frequencies serve as a versatile, high-quality platform for the perturbative sensing of nanoscale materials, successfully characterizing their performance at cryogenic temperatures and extracting the conductivity of an hBN-MLG heterostructure at room temperature.
This study demonstrates the efficacy of entropy spectroscopy in bilayer graphene quantum dots to characterize ground-state degeneracy, confirming a two-fold degeneracy in the one-carrier regime and revealing a previously unobserved non-degenerate ground state in the two-carrier regime attributed to Kane-Mele spin-orbit interaction.
This paper demonstrates that noninvasive terahertz nano-imaging and spectroscopy can effectively correlate sidewall near-field scattering and dielectric responses with superconducting qubit coherence, offering a high-throughput alternative to destructive characterization methods for optimizing quantum circuit performance.
This paper investigates a one-dimensional non-Hermitian superconducting lattice with all internal symmetries, demonstrating how the interplay of pseudo-Hermiticity, sublattice symmetry, and dissipation stabilizes Majorana zero modes and complex spectral features while establishing a topological invariant to map phase diagrams and reveal unique eigenstate correlations.
This study experimentally confirms the existence of a quantum Hall ferromagnetic state with helical edge transport in the layered organic Dirac-fermion system -(ET)I by demonstrating that its characteristic angle-dependent magnetoresistance persists in multilayers but vanishes in Corbino geometry, thereby ruling out the chiral magnetic effect as the underlying mechanism.
This paper investigates the quantum dissipative dynamics of a kicked fluxonium system, demonstrating that its steady-state density matrix converges to a quantum strange attractor analogous to the classical chaotic attractor, with eigenstate localization or delocalization determined by the interplay between dissipation strength and the Ehrenfest time.
