Unveiling the superconducting scenario in multiphase superconductor CeRh2_2As2_2 from space-group symmetry analysis and DFT calculations

This paper investigates the unique superconducting scenario in CeRh2_2As2_2 by combining space-group symmetry analysis and DFT calculations to propose that the observed field-induced transition between low- and high-field phases arises from a change in the internal structure of triplet pairing states (E1u′+E_{1u}^{\prime +}) rather than a conventional singlet-triplet transition, potentially driven by non-symmorphic lattice effects at the Brillouin zone boundary.

A Kapitza Pendulum Route to Supercurrent Tunnel Diodes

This paper proposes and theoretically demonstrates a "Kapitza supercurrent diode" that achieves nonreciprocal supercurrent transport in conventional Josephson junctions by using frequency-modulated parametric driving to dynamically break reciprocity, offering a magnet-free alternative to existing superconducting diode designs.

Superconductivity and magnetism in bilayer nickelates: itinerant perspective

This paper investigates superconductivity and magnetism in bilayer nickelates using an itinerant perspective with RPA-dressed interactions, revealing that the strength of Hund's coupling critically determines whether the system favors ss-wave pairing with (π/2,π/2)(\pi/2, \pi/2) spin-density wave order or dd-wave pairing with (π,π)(\pi, \pi) order.

Gapless superconductivity from extremely dilute magnetic disorder in 2H-NbSe2-xSx

This study reveals that extremely dilute magnetic disorder induces gapless superconductivity in 2H-NbSe2-xSx, a phenomenon driven by Se-S substitution-induced band structure modifications that alter in-gap scattering mechanisms and challenge the conventional understanding of disorder robustness in superconductors.

Direct Observation of the Spillover of High Magnetic Field-induced SC3 Superconductivity Outside the Spin-Polarized State in UTe2

By extending high-field measurements up to 45 T in a high-quality UTe2_2 sample, this study provides direct evidence that the SC3 superconducting phase spills outside the spin-polarized state, supporting the scenario that its pairing is mediated by quantum critical fluctuations.

Interplay of Zeeman field, Rashba spin-orbit interaction, and superconductivity: spin susceptibility

This paper presents a self-consistent theoretical framework using the Bogoliubov-de Gennes Hamiltonian and Kubo formula to analyze how Zeeman fields and Rashba spin-orbit coupling jointly influence the spin susceptibility of ss-wave and pp-wave superconductors, providing quantitative benchmarks for identifying pairing symmetries and interaction strengths in non-centrosymmetric materials.
