Chiral skyrmionic superconductivity from doping a Chern Ferromagnet

This paper demonstrates that hole-doping a Chern ferromagnet can stabilize chiral $f$ -wave superconductivity through the formation and condensation of skyrmionic Cooper pairs, offering a novel microscopic mechanism potentially relevant to superconductivity observed in MoTe $_2$ moiré superlattices.

Upper critical in-plane magnetic field in quasi-2D layered superconductors

This paper presents an analytical framework to model the upper critical in-plane magnetic field in quasi-2D layered superconductors, which, when applied to recent bilayer graphene experiments, reveals a discrepancy in spin-orbit parameters that is likely resolved by an enhanced Landé g-factor.

First-principles evidence for conventional superconductivity in a quasicrystal approximant

This study provides the first *ab initio* confirmation that conventional electron-phonon coupling accurately predicts the superconducting transition temperature of the decagonal Al $_{13}$ Os $_4$ approximant, thereby validating the use of such crystals as proxies for quasicrystals and predicting enhanced superconductivity in related Al-Re and Al-Ir alloys.

Magnetically induced Josephson nano-diodes in field-resilient superconducting microwave circuits

This paper demonstrates that niobium-based superconducting microwave circuits featuring nano-constriction quantum interferometers exhibit a pronounced, field-induced Josephson diode effect in large in-plane magnetic fields, resulting in bias-flux asymmetry and bimodal Kerr nonlinearity that enhance their suitability for high-field hybrid quantum applications.

Nonequilibrium phase transition of dissipative fermionic superfluids: Case study of multi-terminal Josephson junctions

This paper investigates the nonequilibrium dynamics of a triad of fermionic superfluids in a multi-terminal Josephson junction under sudden two-body loss, revealing that dissipation induces a two-step or simultaneous nonequilibrium dynamical phase transition characterized by the vanishing of dc Josephson currents depending on the inter-superfluid tunneling strength.

Directional-dependent Berezinskii-Kosterlitz-Thouless transition at EuO/KTaO $_3$ (111) interfaces

The study reveals that the EuO/KTaO $_3$ (111) interface exhibits a directional-dependent Berezinskii-Kosterlitz-Thouless transition driven by interfacial phase segregation into quasi-one-dimensional textures, resulting in a spontaneous breaking of threefold rotational symmetry and the emergence of exotic superconducting phases beyond conventional physics.

Uniaxial Compression-Induced Anisotropy and Electronic Dimensionality in the Iron-Based Superconductor FeSe

This study reveals that while suppressing nematicity initially enhances the superconducting transition temperature ( $T_c$ ) in FeSe under all compression modes, further in-plane compression uniquely suppresses $T_c$ by increasing the electronic structure's three-dimensionality via a Lifshitz-type transition, whereas out-of-plane compression continues to boost $T_c$ .
