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 study demonstrates that high-pressure thermal decomposition of hydrogen-rich precursors enables the over-hydrogenation of LaFeSi to stabilize a new, orthorhombic, semiconductor-like LaFeSiH phase, which can subsequently be tuned back to a superconducting state through controlled hydrogen release.
This paper reports the discovery of a new YbSb-type monoclinic polymorph of LaSb stabilized in thin films via molecular beam epitaxy, which exhibits superconductivity at 2 K with an enhanced transition temperature and a long coherence length of 140 nm.
This study reports the synthesis of high-quality, ambient-pressure flux-grown bilayer nickelate single crystals that exhibit bulk superconductivity with a transition temperature reaching up to 96 K under high pressure, establishing a correlation between in-plane lattice distortion and enhanced superconductivity.
This paper establishes that the long-standing assumption of co-breaking time-reversal and inversion symmetries is necessary but insufficient for the intrinsic superconducting diode effect, and instead proposes a universal diagnostic criterion based on two inequalities derived from the bare Hamiltonian alongside a graph-theoretic construction for designing nonreciprocal models.
This paper theoretically investigates a superconductor-topological insulator bilayer model, demonstrating that increasing interlayer tunneling and hybridization can spatially separate Majorana zero modes from Caroli-de Gennes-Matricon states and induce distinct -wave-like features, thereby providing a framework for stabilizing and identifying Majorana modes in engineered topological systems.
This paper predicts that the unambiguous detection of the superconducting Higgs mode can be achieved in microwave-irradiated asymmetric and transparent Josephson junctions by observing resonant enhancements in the second harmonic of the current-phase relation at zero bias and the AC Josephson current at finite bias.
This paper investigates three-dimensional superconducting altermagnets to demonstrate how the interplay between superconducting and altermagnetic symmetries generates topologically protected crossed surface flat bands and Bogoliubov-Fermi surfaces, which collectively produce distinct charge conductance signatures for experimental detection.
This paper reviews recent theoretical advances in the charge dynamics of high-temperature cuprate superconductors, highlighting the universal emergence of low-energy acoustic-like plasmons and the distinct dual-structure charge behavior in electron-doped systems, while proposing a unified scenario to reconcile unresolved charge-order phenomena in hole-doped materials.
