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 argues that the reported magnetic field-induced changes in the lattice structure and charge density wave intensity of RbVSb, previously interpreted as evidence of piezomagnetism, are actually artifacts caused by STM tip reconfiguration and instrumental distortions rather than intrinsic sample properties.
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 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 study demonstrates that the Kosterlitz-Thouless transition temperature in uniformly confined superfluid He is accurately predicted by incorporating two-dimensional roton excitations into static and dynamical theories, thereby resolving long-standing discrepancies without relying on traditional coherence length scaling or ad-hoc free vortex contributions.
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.
By utilizing focused-ion-beam milling to expose pristine (110) side surfaces of overdoped LaSrCuO, this study reveals that while the superconducting spectral gap is suppressed as expected, the anticipated zero-energy flat bands are also absent due to bulk disorder rather than surface roughness, providing the first momentum-resolved evidence that disorder prevents the emergence of these topological states and their associated correlated orders.
This study demonstrates that a Pechini sol-gel synthesis method with cationic molecular mixing can efficiently produce high-quality Li-doped Bi-2223 superconductors, achieving a maximum critical temperature of 111.4 K at 5 mol% Li doping while revealing unique layer-by-layer crystalline growth and flux creep mechanisms.
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 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.
