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 utilizes inelastic neutron scattering on Pr and Nd-doped LaNiO to reveal that rare-earth doping splits the characteristic 45 meV spin fluctuation mode and enhances interlayer magnetic coupling, supporting a stripe-type Heisenberg model with increased values of 69–73 meV.
Using scanning tunneling microscopy and optical second-harmonic generation, researchers discovered that the charge density wave state in kagome metals AV3Sb5 spontaneously breaks inversion symmetry to form a parity-violating chiral polar-nematic order, which couples with superconductivity to enable electric field control of chirality and provides microscopic insights into unconventional superconductivity and related quantum phenomena.
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 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 introduces a fully in situ, multi-angle stencil lithography technique to fabricate clean hybrid superconductor-topological insulator charge islands, demonstrating robust proximity-induced superconductivity and Coulomb blockade without post-growth processing.
This study demonstrates that electrochemical topotactic deintercalation of lead from the centrosymmetric parent compound AuPbP induces a cooperative structural rearrangement to form the rare polar metal AuPbP, which exhibits noncentrosymmetric superconductivity below 1.52 K with a gap structure suggestive of mixed singlet-triplet pairing.
This paper proposes a symmetry-based phenomenological framework for cuprate NMR data that disentangles copper shifts into two components (A and B), revealing that the pseudogap arises from their coupling and that optimal superconductivity requires a specific match between these components, while the highest transition temperatures are determined by nuclear relaxation and charge sharing rather than shift data alone.
This study establishes Pd2ZrIn as a weakly coupled, dirty-limit, type-II superconductor with a fully gapped, nodeless s-wave order parameter and preserved time-reversal symmetry, based on comprehensive muon spin relaxation and rotation measurements alongside electrical and magnetic characterization.
