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 paper demonstrates that periodic high-frequency driving of a half-filled Fermi-Hubbard model can induce unconventional d-wave superconductivity by renormalizing hopping parameters to frustrate antiferromagnetic order and lift kinetic constraints, thereby stabilizing a prethermal superconducting phase without the need for chemical doping.
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.
This paper establishes a general microscopic framework for four-fermion composite states and applies it to a specific model in two and three dimensions to demonstrate the existence of time-reversal symmetry-breaking electron quadrupling order, while calculating its specific heat and electron density of states.
Using low-energy muon spin spectroscopy and secondary-ion mass spectrometry, this study directly measures the intrinsic London penetration depth and BCS coherence length of oxygen-doped niobium, revealing that clean niobium lies at the boundary between type-I and type-II superconductivity with a Ginzburg-Landau parameter of 0.70(5).
This study demonstrates that a MoRe-based superconducting resonator exhibits a pronounced nonlinear response to pulsed infrared irradiation driven by nonequilibrium quasiparticle dynamics rather than thermal heating, confirming its potential for microwave kinetic-inductance detector applications.
This study demonstrates that circular Josephson vortex shift registers can achieve energy dissipation below Landauer's thermodynamic limit by preserving information, while also characterizing the higher dissipation and propagation dynamics in nonuniform registers incorporating nSQUID components.
This study employs first-principles density functional theory calculations to comprehensively characterize the structural, mechanical, electronic, vibrational, and optical properties of LaRh2X2 (X = Al, Ga, In) superconductors, confirming their thermodynamic and mechanical stability, ductile metallic nature, and weak electron-phonon coupling while identifying dynamical instability in the In-based variant and potential applications in optical data storage.
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.
