This paper proposes that the superconducting state observed in twisted MoTe is a chiral -wave topological superconductor featuring an emergent double-vortex lattice with half-integer Chern number, providing a unified theoretical framework for understanding the coexistence of fractional quantum anomalous Hall effects and topological superconductivity in twisted semiconductors.
This paper demonstrates that a superconducting quantum circuit utilizing Josephson junctions as a Quantum Reservoir Computing system can accurately classify complex statistical distributions and identify regimes in correlated time series, often outperforming classical methods when data is limited, thereby showcasing the potential of noise-resilient quantum learning on current hardware.
This paper investigates how shunt resistors control the dynamics and onset of resistive phases, such as hot-spot and phase-slippage events, in superconducting wires operating below their critical current by influencing dynamic current redistribution and local heating properties.
This paper introduces a minimal, scalable shunted superconducting wirelet neuron that exhibits tunable spiking dynamics and demonstrates accurate pattern recognition capabilities, establishing a promising energy-efficient building block for cryogenic neuromorphic computing.
Using dynamical mean-field theory, this study reveals that a single-layer Hubbard model coupled to superconductors exhibits a first-order phase transition between a Mott-like insulating state and a proximitized superconducting state, where phase bias and junction transparency can tune the system between conducting and insulating regimes.
This paper reports the realization of de Gennes' predicted absolute superconducting switch by demonstrating that $EuS/Au/Nb/EuS$ structures, leveraging a heavy metal interface to enhance spin-mixing conductance, can completely quench superconductivity in the parallel magnetic configuration down to 20 mK, thereby achieving a near-unity switching ratio essential for low-power electronics.
This paper demonstrates that while the effective homogeneous exchange field model accurately describes thin-film superconductor/insulating magnet heterostructures by producing well-defined spin splitting, it fails for superconductor/metallic magnet systems where the effect is chaotic, though the latter still support significant triplet correlations suitable for spintronics.
This study reports high-precision muon Knight shift measurements on a single crystal of SrRuO that successfully eliminate stray-field artifacts to confirm a significant reduction in spin susceptibility below the critical temperature, providing strong evidence for spin-singlet-like pairing symmetry in this -electron superconductor.
Using ultralow-temperature spectroscopic-imaging scanning tunneling microscopy, the study reveals that while the superconducting gap in 2H-NbSe2 remains spatially uniform, the spectral weight near the coherence peak is modulated by the charge density wave in a pattern dictated by the surface's broken in-plane inversion symmetry and potential Ising spin-orbit coupling.
This paper reviews emerging evidence for time-reversal symmetry breaking in low-temperature superconductors, proposing a new class of "fragile magnetic superconductors" modeled by triplet pairing while critically examining whether the muon spin relaxation measurement process itself might induce the observed symmetry breaking, using LaNiGa as a key case study.
