Below are the most recent papers in this dynamic area of condensed matter physics, ready for you to explore.
This paper identifies a non-equilibrium state induced by current bias in a Rashba system as the microscopic origin of the Josephson diode effect, demonstrating that an in-plane magnetic field perpendicular to the current creates an asymmetric Josephson coupling whose magnitude and sign can be optimized by tuning the electrode distance.
This paper investigates tungsten silicide fluxonium qubits and resonators fabricated from quasi-two-dimensional amorphous films, revealing that energy loss is primarily driven by localized quasiparticles trapped in spatial variations of the superconducting gap, with loss increasing alongside the level of disorder.
This review examines how recent advances in materials science, device characterization, and nanofabrication are overcoming critical challenges in Josephson junction reproducibility, dissipation, and scalability to enable the transition from laboratory components to industrial-scale superconducting quantum processors.
This paper introduces the polaron-transformed canonically consistent quantum master equation (PT-CCQME), a unified theoretical framework that extends the accuracy of open quantum system simulations to strong system-bath interaction regimes while maintaining low numerical complexity, as validated by excellent agreement with exact TEMPO simulations on the spin-boson model.
This paper proposes that a vibrationally-mediated Dzyaloshinskii-Moriya interaction, driven by low-energy torsional modes modulating hopping and spin-orbit coupling in donor-acceptor molecules, serves as the predictive mechanism for Chirality-Induced Spin Selectivity, successfully explaining experimental magnetic field and temperature dependencies.
This paper proves the existence of topologically nontrivial energy-minimizing maps with higher degrees in a magnetic skyrmion model by strategically inserting truncated Belavin-Polyakov profiles into lower-degree configurations, provided the domain is sufficiently large or slender to prevent degree loss.
This study demonstrates that the ferromagnetic ground state of single-crystalline NdGaSi splits quasi-flat 4f bands near the Fermi energy, enabling localized f-electrons to directly generate a record-breaking intrinsic anomalous Hall conductivity of 1165 cm, a phenomenon absent in its non-magnetic analog NdAlSi.
This paper derives a reduced energy functional for ultrathin ferromagnetic multilayers hosting skyrmions and demonstrates that in bilayer systems, the global energy minimizers consist of two antiparallel Néel skyrmions stabilized by stray field coupling.
This paper establishes a unified theoretical framework linking orbital and heat magnetizations to experimentally accessible excitation spectra via generalized sum rules and chiral thermoelectric probes, enabling the direct measurement of these ground-state properties through dichroic measurements in quantum-engineered platforms.
This paper reports the first experimental demonstration of electrically driven plasmon-polaritonic bistability in graphene/hexagonal-boron-nitride/graphene tunneling transistors, achieved through momentum-conserving resonant tunneling of Dirac electrons and tunable via load resistance and electrostatic gating.
