This paper proposes and theoretically demonstrates a "Kapitza supercurrent diode" that achieves nonreciprocal supercurrent transport in conventional Josephson junctions by using frequency-modulated parametric driving to dynamically break reciprocity, offering a magnet-free alternative to existing superconducting diode designs.
This paper proposes a symplectic quantum geometric tensor (SQGT) to provide a complete geometric characterization of bosonic Bogoliubov quasiparticles, linking its real and imaginary parts to a quantum metric and Berry curvature, respectively, and demonstrating how to measure these components via excitation rates and their connection to anomalous velocities.
This paper addresses the instability and reduced coherence of gate-tunable superconducting transmon qubits (gatemons) by developing characterization methods and demonstrating that specific shunt capacitor designs, particularly grounded configurations, enable highly reliable frequency tuning with 1 MHz precision and improved stability.
This study reveals that the PbSe/PbTe monolayer heterostructure achieves ultralow lattice thermal conductivity and an exceptional thermoelectric figure of merit (ZT) of 5.3 at 800 K due to its unique corrugated configuration, weak interatomic interactions, and the dominant heat-carrying role of highly anharmonic optical phonons.
This paper presents a gentle, lithography-free via transfer method to construct high-quality 3D superconductor-graphene Josephson junctions with low contact resistance, enabling the observation of gate-tunable supercurrents and providing a pathway for engineering novel superconducting heterostructures on sensitive materials.
This paper demonstrates that in-plane electric fields induce resonant Zener interferometry in van der Waals heterostructures, producing observable Landau-Zener-Stuckelberg oscillations and distinct resonances in lateral conductance that serve as a direct probe of coherent quantum dynamics for advanced material engineering.
This Letter derives a finite-time thermodynamic uncertainty relation for open quantum systems under Markovian feedback control, demonstrating how information-based control suppresses current fluctuations and enhances precision by linking entropy production with quantum mutual information.
This study demonstrates that monochromatic irradiation of zigzag monolayer WSe nanoribbons, modeled via a tight-binding Floquet framework and density functional theory, significantly enhances the thermoelectric figure of merit () by reshaping electronic band structures and reducing lattice thermal conductivity through anharmonic scattering.
This paper investigates electron pumping in quantum dots driven by coupling-energy modulations in the absence of lowest-order tunneling, deriving exact solutions for two distinct setups—switching couplings and measuring occupation—to analyze the roles of off-resonant tunneling and coherences in optimizing current and energy efficiency.
This paper develops a unified semiclassical theory demonstrating that asymmetric impurity scattering in altermagnets like FeSb2 generates dominant, time-reversal-even extrinsic spin-splitter currents, distinguishing them from previously studied symmetric scattering mechanisms.
