This theoretical study establishes unconventional -wave magnets as a versatile platform for realizing a rich landscape of emergent superconducting phases, including topological superconductivity with Majorana edge modes, Bogoliubov Fermi surfaces, and the superconducting diode effect, within a unified microscopic framework.
By integrating local electromagnetic shielding and low-pass filtering directly at the cryogenic scan head, this study overcomes dynamical Coulomb blockade limitations to achieve a record energy resolution of 3.7 μeV, thereby revealing a novel coupling between atomic-scale Josephson currents and macroscopic cavity quantum electrodynamics modes.
This study demonstrates that bulk single crystals of the triplet superconductor uranium ditelluride (UTe) exhibit an intrinsic, electrically controllable memory effect where magnetic-field-tuned current pulses switch the material between metastable states of distinct critical currents, offering a promising pathway for ultralow-power superconducting memory in cryogenic computing.
This paper calculates the anomalous Hall conductivity in rhombohedral stacked multilayer graphene using the Kubo-Streda approach, accounting for various impurity scattering mechanisms and band warping effects to explain the experimentally observed spontaneous spin-valley polarized quarter metal state.
This paper proposes that nematic order in multilayer graphene enhances superconductivity by breaking symmetry to reshape Bloch wavefunctions and amplify the quantum metric, thereby significantly boosting pairing strength through the quantum geometric Kohn-Luttinger mechanism.
This paper predicts that confining light in infrared cavities can control the Ginzburg-Landau stiffness of superconductors by renormalizing the Cooper-pair kinetic mass through photon-mediated repulsive interactions, an effect that is particularly significant in low-temperature materials and tunable via cavity length.
Motivated by recent experiments, this paper derives general expressions for photonic heat transport through a Josephson junction in a dissipative environment, demonstrating that the heat current remains sensitive to Josephson coupling on the insulating side with opposite behaviors for series and parallel configurations, while also predicting heat rectification properties.
This paper presents a method to map the individual positions of surface two-level-systems (TLS) on a superconducting transmon qubit by utilizing local electric fields from on-chip gate electrodes, revealing that TLS density is significantly enhanced near the Josephson junction leads rather than the larger capacitor area, thereby guiding future qubit design and fabrication improvements.
This paper theoretically demonstrates an exact duality mapping between the low-energy charge-dependent bands of a charge-biased Josephson tunnel junction coupled to a finite transmission line and its flux-biased counterpart, revealing that both systems converge to a resistively shunted junction in the infinite-length limit and highlighting the system's intrinsic self-duality and critical behavior.
