This paper predicts that density-balanced, mass-asymmetric electron-hole bilayers can host a unique electron-liquid hole-crystal phase where acoustic plasmons mediate BCS-type superconductivity, offering a tunable platform for experimental realization in van der Waals heterostructures.
This study reveals that magnetic skyrmions in chiral films exhibit intrinsic, anisotropic, and oscillatory interactions analogous to RKKY coupling, driven by a universal wavy tail in their spin texture, which offers a new physical principle for designing skyrmion-based devices for spintronics and neuromorphic computing.
This study presents the direct spectroscopic observation of Cooper quartet resonances in a graphene three-terminal Josephson junction, revealing their topological origin through phase-controlled hybridization of Andreev bound states and demonstrating the potential for engineering exotic superconducting states in multiterminal devices.
This study proposes and demonstrates that graphene/AlGaN/GaN heterostructures serve as a promising platform for investigating drag and two-stream instability effects, evidenced by the observation of quantum oscillations in graphene drag current at low temperatures and its subsequent enhancement as temperature rises.
This study demonstrates that voltage-biased three-dimensional superconducting films exhibit negative differential conductance and nonequilibrium phase coexistence with intermediate resistances, revealing dissipative states and validating the principle of minimum entropy production that remain inaccessible through conventional current-biasing methods.
This paper presents a microscopic model and numerical solution of the three-dimensional Schrödinger equation to investigate how external electric fields (0–6 kV/cm) affect the energy, binding energy, radiative broadening, static dipole moment, and dissociation threshold of heavy-hole and light-hole excitons in GaAs/AlGaAs quantum wells of varying widths up to 100 nm, ultimately enabling the modeling of reflection spectra for these structures.
This paper demonstrates that applying a concatenated continuous drive (CCD) with phase-modulated microwave signals to a natural silicon metal-oxide-semiconductor quantum dot significantly extends spin coherence times and improves single-qubit gate fidelity from 95% to 99%, thereby overcoming environmental noise limitations in isotopically natural silicon.
This review comprehensively examines the fabrication, unique mechanical and physical properties, and diverse applications of freestanding thin-film materials while addressing current challenges and outlining future prospects in fields ranging from flexible electronics to quantum sensing.
This paper theoretically demonstrates that driving a spin qubit in a parabolic quantum wire with a bichromatic field generates confinement-tunable synthetic gauge fields and diverse Floquet topological phenomena, including non-Abelian geometric phases and unconventional oscillations, thereby establishing a scalable platform for fault-tolerant quantum information processing and holonomic quantum computation.
This study demonstrates that integrating a thin Ruthenium Oxide (RuO2) layer into a Platinum (Pt) spin-orbit torque stack significantly enhances damping-like efficiency and enables field-free perpendicular magnetization switching, thereby creating reliable multi-state synapses that achieve high accuracy in neuromorphic image recognition tasks.
