This paper introduces an interpretable Gaussian process model called GP-, which utilizes electron-affinity difference distributions to predict superconducting transition temperatures, successfully validating its approach on nickelates and experimentally discovering a new superconductor, PtPbBi, with a critical temperature of approximately 3 K.
Using the hole-doped square-lattice - model, this study demonstrates that quantum phase fluctuations fundamentally alter the mean-field picture of time-reversal symmetry breaking in unconventional superconductors by inducing a first-order transition and phase separation between symmetric and asymmetric phases, thereby significantly narrowing the stability region of the exotic $s+id$ state.
This paper introduces a fit-free nematic response function model that combines with the two-temperature model to directly extract and quantify the anisotropic electronic thermalization timescales (110–230 fs) in nematic iron-based superconductors, offering a powerful alternative to complex data-fitting procedures.
Using resonant inelastic x-ray scattering, this study reveals that the significantly lower superconducting transition temperature in trilayer compared to bilayer arises from weaker electronic correlations and a substantially reduced interlayer magnetic exchange interaction.
This paper employs the Schwinger-Keldysh formalism to construct a symmetry-constrained effective field theory for s-wave superconducting phase transitions that reproduces Ginzburg-Landau equations, describes overdamped Higgs and absorbed phase modes near the critical point, and validates its structure and coefficients using holographic techniques to reveal complex relaxation dynamics characteristic of strongly coupled systems.
This study demonstrates that biaxial compressive strain in LaNiO thin films primarily enhances Jahn-Teller splitting by elongating outer apical Ni-O bonds, identifying this distortion as the key microscopic parameter for optimizing superconductivity in bilayer nickelates.
This paper demonstrates that hole-doping a Chern ferromagnet can stabilize chiral -wave superconductivity through the formation and condensation of skyrmionic Cooper pairs, offering a novel microscopic mechanism potentially relevant to superconductivity observed in MoTe moiré superlattices.
This paper presents an analytical framework to model the upper critical in-plane magnetic field in quasi-2D layered superconductors, which, when applied to recent bilayer graphene experiments, reveals a discrepancy in spin-orbit parameters that is likely resolved by an enhanced Landé g-factor.
This paper reports the discovery of superconductivity at a transition temperature of approximately 16.3 K in the newly synthesized, non-centrosymmetric layered compound NaVSeO, marking the first realization of superconductivity in an altermagnetic candidate and offering a promising platform for exploring exotic superconducting states and bridging high-temperature superconductor families.
This study reveals that while suppressing nematicity initially enhances the superconducting transition temperature () in FeSe under all compression modes, further in-plane compression uniquely suppresses by increasing the electronic structure's three-dimensionality via a Lifshitz-type transition, whereas out-of-plane compression continues to boost .
