This study employs time-resolved optical spectroscopy to characterize the ultrafast dynamics of high-energy electronic excitations and phonon modes in bilayer La3Ni2O7, revealing distinct density-wave gaps, relaxation behaviors, and electron-phonon coupling mechanisms that provide critical insights into the material's complex gap structure and its link to high-temperature superconductivity.
This paper reports the systematic observation of a pronounced anomalous phonon thermal Hall effect in the altermagnet candidates MnTe and CrSb, establishing this phenomenon as an intrinsic feature of altermagnets and providing a sensitive probe for identifying this new class of quantum magnets.
This study investigates the electron-phonon mediated pairing symmetry in pressured LaNiO using two distinct coupling models, revealing that interlayer coupling favors an -wave state while intralayer coupling promotes an -wave symmetry.
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.
This study establishes that the superconducting properties of niobium-based high-entropy alloys are primarily governed by the position of the niobium d-band relative to the Fermi level, with lattice distortion acting as a secondary modifier, thereby providing a mechanism-informed design strategy for optimizing these materials.
This paper proposes that elliptically polarized light can drive an altermagnet-superconductor heterostructure into Floquet chiral topological superconducting phases with tunable Chern numbers up to four, leveraging the interplay between altermagnetism, mixed pairing symmetries, and periodic driving.
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.
The paper demonstrates that Superconductor-Insulator-2D electron gas tunnel junctions can generate strong nonlinear thermoelectricity and achieve near-Carnot efficiency () through a novel mechanism, offering superior performance and easier fabrication compared to analogous solid-state devices.
