Superconductivity is a fascinating state of matter where materials conduct electricity without any resistance, often defying our everyday expectations of how energy behaves. Researchers in this field explore the quantum mechanics behind these phenomena, seeking new materials that can operate at higher temperatures or under more practical conditions. This work holds the promise of revolutionizing everything from power grids to medical imaging devices, making the invisible world of quantum physics feel increasingly tangible and useful.

This paper demonstrates that microwave irradiation of Josephson junctions containing Yu-Shiba-Rusinov states, combined with broken particle-hole and inversion symmetries, induces a tunable diode effect characterized by asymmetric critical currents that can vanish entirely for one polarity.
This paper theoretically demonstrates that a square superconducting network decorated with spin-polarized magnetic adatoms can host a bulk-dissociated topological superconducting phase with unique features like nodal lines and co-existing edge and corner modes, achieved through geometric design without the need for spin-orbit coupling.
This study demonstrates that annealing-induced grain coarsening in NbRe films transforms their vortex dynamics from flux-flow instability to a regime characterized by multiple voltage kinks, which are attributed to the nucleation of normal domains and offer potential for discrete-resistance switching applications.
Using large-scale DMRG simulations and slave-boson mean-field theory, this study reveals that next-nearest-neighbor hopping in the doped honeycomb - model induces a robust -wave superconducting phase coexisting with armchair stripes, while highlighting a significant dependence of competing charge and superconducting orders on cylinder boundary geometry.
This study demonstrates that Zn substitution in FeSe single crystals induces a nonmonotonic evolution of the superconducting transition temperature driven by enhanced scattering rather than simple pair breaking, while preserving robust multigap extended s-wave + s-wave pairing that imposes stringent constraints on candidate pairing mechanisms.
This paper reveals that in sufficiently thin-film superconductors with a realistic Ginzburg-Landau parameter, the magnetic field screening around vortices follows a universal curve scaling with sample thickness, rather than the exponential decay of bulk materials or the power-law predicted by Pearl.
This study demonstrates that applying hydrostatic pressure to the -wave altermagnet candidate CsVSeO suppresses its weakly insulating parent state and induces a reproducible, field-sensitive superconducting-like transition below 3 K, suggesting a potential link between altermagnetism and unconventional superconductivity.
This paper theoretically demonstrates that a nonideal interface with finite resistance in a superconductor-normal metal bilayer can nonmonotonically influence and even enhance the orbital superconducting diode effect compared to an ideal interface, particularly when the bilayer thickness is small relative to the coherence length.
By incorporating freestanding infinite-layer NdSrNiO membranes into a diamond anvil cell, researchers demonstrated that hydrostatic pressure induces a strong, linear increase in superconducting transition temperature up to ~90 GPa without saturation, reaching near liquid nitrogen temperatures.
This study provides unambiguous evidence of tunable, two-dimensional superconductivity at CaZrO3/KTaO3(001) heterointerfaces, characterized by a Berezinskii-Kosterlitz-Thouless transition and a strong dependence of the critical temperature on carrier density and crystallographic orientation.
