This paper demonstrates that strong electron-electron correlations in a Hubbard model with an odd number of electrons can spontaneously break time-reversal and mirror symmetries to induce a zero-field Josephson diode effect, establishing correlation as a distinct mechanism for nonreciprocal superconducting transport.
This paper presents a generalized Usadel equation-based framework for analyzing the nonlinear properties of supercurrent-carrying single and multi-layer superconducting thin-films, which is validated by experimental measurements of transition temperatures and serves as a critical tool for optimizing the design of quantum sensors and computing devices.
This paper presents the experimental realization of a non-degenerate pumping scheme for a NbN-based superconducting resonator parametric amplifier, which achieves a peak gain of 26 dB, demonstrates improved stability over degenerate schemes, and enables phase-sensitive amplification with 6 dB of squeezing.
This study demonstrates that growing aluminum thin films at cryogenic temperatures induces structural disorder and smaller grain sizes, which enhance superconducting properties and kinetic inductance while altering optical characteristics, yet result in microwave resonators with quality factors dominated by two-level system loss similar to room-temperature films.
This paper proposes a microscopic mechanism for the stripe charge-density-wave in kagome metal CsVSb, demonstrating that short-range magnetic fluctuations within a 12-site Hubbard model drive a bond order that reconstructs the Fermi surface to produce a stripe CDW consistent with experimental observations.
This paper investigates the electronic Raman scattering response in superconducting nickelates by analyzing various multiorbital models and pairing symmetries to identify characteristic fingerprints that can help determine the minimal model and pairing mechanism underlying high- superconductivity in these materials.
This paper presents a gate-controlled, lithography-compatible nanoscale electrothermal-switch superconducting diode that achieves high-efficiency, electrically programmable nonreciprocal transport through dynamic inversion symmetry breaking, enabling scalable reconfigurable superconducting circuits.
This paper investigates vestigial phases in 3D chiral superconductors with cubic symmetry, revealing a distinct tetracritical phase diagram and demonstrating that thermal fluctuations can melt primary chiral orders into a chiral metal or induce exotic charge-4e and charge-6e superconducting states.
Path integral molecular dynamics simulations reveal that LiAuH and LiAgH are kinetically unstable under ambient pressure, with LiAuH undergoing hydrogen dimerization that significantly reduces its predicted superconducting transition temperature to 22 K.
This paper proposes that vacuum fluctuations of a quantized magnetic flux from an LC resonator in a circuit QED environment can mediate long-range attractive interactions between angular momentum states in two-dimensional electron systems, leading to the formation of a tunable, high-temperature chiral pair-density-wave superconducting state.
