This study demonstrates that substituting Eu in Nd1-xEuxNiO2 thin films induces re-entrant unconventional superconductivity characterized by a significantly enhanced superconducting gap and magnetic-field-enhanced behavior, indicating a transition to a strong-coupling pairing regime driven by interactions between magnetic Eu ions and the Ni dx2-y2 orbitals.
This paper investigates the impact of particle-hole fluctuations on the Berezinskii-Kosterlitz-Thouless transition in two-dimensional Fermi gases across the BCS-BEC crossover, demonstrating that self-consistently including these fluctuations screens the pairing interaction and significantly reduces the transition temperature, thereby achieving quantitative agreement with experimental data and quantum Monte Carlo simulations.
This paper investigates a two-dimensional superconducting system with a periodically modulated order parameter, demonstrating that the modulation period determines the topological winding number and establishing an analytic bulk-edge connection that explains the emergence of localized edge states from the bulk spectrum.
This paper reports the first small-angle neutron scattering measurements of the microscopic parameters governing thermodynamic equilibrium in the type-II superconductor niobium, specifically the orbital radius of Cooper pairs, the radius of field-induced currents, and the Cooper pair density, thereby opening new avenues for understanding superconductivity mechanisms.
This paper presents a systematic theoretical framework based on a functional-integral formulation that consistently incorporates static white-noise disorder and Gaussian pairing fluctuations to describe the BCS-BEC crossover near the critical temperature, successfully recovering established limits while providing a robust foundation for analyzing intermediate regimes in both continuum and lattice systems.
By employing angle-resolved photoemission spectroscopy under tunable magnetic fields, this study reveals that the time-reversal symmetry breaking in the kagome superconductor CsVSb originates from vanadium Van Hove singularities and exhibits momentum-selective piezomagnetic responses, demonstrating how magnetic fields can disentangle intertwined electronic orders.
This paper demonstrates that reentrant superconductivity in strong magnetic fields generically arises from the competition between spinful and spin-polarized spin-triplet instabilities, which a minimal Ginzburg-Landau theory shows can reorganize the superconducting hierarchy to produce a characteristic reentrant phase independent of microscopic details.
This paper proposes a universal theoretical framework using twisted homobilayers of -valley square-lattice systems, specifically identifying ZnF as a promising candidate to simulate the effective models of high-temperature superconductors like cuprates and iron-based materials by realizing single-orbital and multi-orbital Hubbard models within their moiré bands.
This review summarizes recent advancements in achieving ambient-pressure superconductivity in bilayer nickelate LaNiO thin films through epitaxial strain engineering, while also examining experimental characterizations, improvements, and theoretical insights into their electronic structure and pairing symmetry.
High-resolution thermal conductivity measurements on high-quality UTe single crystals reveal a fully gapped superconducting state with a pseudo point-nodal structure, where gap minima approach but do not reach zero, thereby resolving conflicting reports on the gap anisotropy and excluding non-unitary mixing of pairing symmetries.
