This first-principles study confirms the structural and dynamical stability of the Janus Ti2CSH monolayer and predicts it to be a phonon-mediated superconductor with a critical temperature of 22.6 K, highlighting its potential for quantum and nanoscale applications.
This paper proposes a phenomenological quantitative theory based on a time-dependent Ginzburg-Landau framework to explain the field-induced superconductor-to-insulator transition in disordered 2D systems, where Cooper-pair fluctuations condense into localized mesoscopic puddles that eventually break down via quantum tunneling, successfully reproducing experimental resistance data and the single crossing point observed in amorphous Indium-Oxide thin films.
This study demonstrates that thermal annealing of eutectic Hf-Nb-Sc-Ti-Zr high-entropy alloys significantly enhances their superconducting critical temperature to a maximum of 9.93 K and critical current density by expanding eutectic regions and inducing lattice strain, which are identified as the key mechanisms driving these improved properties.
This study challenges the specific "high-entropy effect" hypothesis regarding phonon lifetime in quinary alloys by revealing a universal negative correlation between the electron-phonon coupling constant and Debye temperature across bcc superconducting alloys of varying complexity, while also proposing Vickers microhardness as a rapid screening metric for estimating the Debye temperature.
This paper introduces Replica Scanning Tunneling Microscopy (R-STM), a novel technique that bridges atomic and mesoscopic length scales by utilizing replica signals to efficiently track atomic-scale electronic modulations over large areas, demonstrating that the pair density modulation in superconducting FeSe persists consistently up to hundreds of nanometers.
By combining low-temperature penetration depth and specific heat measurements with high upper critical field data, this study demonstrates that LiMoO exhibits a moderately-coupled, fully-gapped superconducting state with marked anisotropy, supporting the existence of a nodeless, possibly odd-parity spin-triplet order parameter emerging from a Tomonaga-Luttinger liquid normal state.
This paper presents a machine-learning-guided protocol that integrates first-principles calculations and tight-binding modeling to accurately identify pairing symmetries in Ising superconductors, such as monolayer NbSe2, by analyzing quasiparticle interference data.
This study investigates vortex dynamics in a two-dimensional superconductor at the KTaO surface, identifying regimes of quantum and thermally activated vortex tunneling as well as complex switching behaviors driven by pinned vortex configurations.
Field-angle-resolved specific heat measurements on a high-quality UTe crystal reveal a distinct linear magnetic field dependence along the axis, providing crucial evidence for nodal quasiparticle excitations that support theoretical models of either point nodes or line nodes in its spin-triplet superconducting state.
This study demonstrates that spatially periodic network patterns in infinite-layer samarium nickelate films induce a superconductor-insulator transition driven by enhanced superconducting fluctuations, revealing direct evidence of 2e Cooper pairing and the emergence of two distinct anomalous metallic phases characterized by bosonic excitations and dynamic vortex roles.
