This paper demonstrates that the tunable - lattice model supports enhanced superconductivity and a geometrically dominated superfluid weight, where tuning the parameter and on-site asymmetries allows for control over the quantum metric and transition temperature, offering a promising platform for realizing tunable quantum materials.
This paper proposes that anisotropic electron-phonon coupling combined with screened Coulomb repulsion drives nodal topological superconductivity on the PtBi surface, while predicting that enhanced Coulomb screening could transform this state into a nodeless superconductor with a higher critical temperature.
This paper demonstrates a gate-tunable double-loop SQUID that achieves a superconducting diode efficiency exceeding 50% by independently controlling the harmonic content and amplitude of three interfering current-phase relationships through series Josephson junctions.
This paper reports the successful establishment and validation of a magneto-optical Kerr effect (MOKE) measurement setup capable of operating under bipolar pulsed magnetic fields up to 13.1 T, demonstrating its accuracy through agreement with static-field results on Fe3O4 and its utility for rapidly characterizing the hysteretic properties of various permanent magnets.
Using determinant quantum Monte Carlo simulations, this study reveals that while superconducting transition temperatures are modestly enhanced near Van Hove singularities in the weak-coupling regime, the global maximum for the two-dimensional attractive Hubbard model actually occurs at intermediate interaction strengths and electron densities unrelated to the non-interacting density of states features.
This study investigates the anomalous low-temperature magnetotransport in the kagome metal CsCrSb under hydrostatic pressure, revealing complex signatures below 30 K that suggest the existence of an exotic electronic order potentially analogous to the charge-density-wave state in its sister compound CsVSb.
This study utilizes high-pressure synthesis and transport techniques to systematically investigate bilayer nickelates, revealing that controlled band width and hole doping can tune the superconducting phase and uncover multiple density-wave anomalies in the nonsuperconducting state.
This study demonstrates that (101)-oriented RuO₂ thin films, a candidate altermagnet, exhibit giant room-temperature third-order electrical transport responses driven by simultaneous T-odd and T-even quantum geometric quantities, providing a robust method to detect Néel order and a versatile platform for quantum spintronic devices.
This paper presents a full microscopic treatment of mesoscopic hybrid regions in Kitaev chains to derive analytical expressions for renormalized couplings and sweet-spot conditions, revealing that parity-crossings of spin-split Andreev bound states define optimal operating windows where Majorana zero modes are simultaneously well-localized and protected by a large excitation gap.
This study demonstrates that the resistive transition and vortex dynamics in MgB thin films are critically governed by microstructural defects and film-buffer interface properties, where single-crystal films with buffer-layer roughness exhibit superior current-carrying capacity and stronger pinning compared to textured films due to enhanced order parameter variations and lower thermal boundary resistance.
