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 substituting Eu in Nd1-xEuxNiO2 thin films induces re-entrant unconventional superconductivity characterized by a significantly enhanced superconducting gap and magnetic-field-enhanced behavior, indicating a transition to a strong-coupling pairing regime driven by interactions between magnetic Eu ions and the Ni dx2-y2 orbitals.
This paper investigates a two-dimensional superconducting system with a periodically modulated order parameter, demonstrating that the modulation period determines the topological winding number and establishing an analytic bulk-edge connection that explains the emergence of localized edge states from the bulk spectrum.
This paper reports the first small-angle neutron scattering measurements of the microscopic parameters governing thermodynamic equilibrium in the type-II superconductor niobium, specifically the orbital radius of Cooper pairs, the radius of field-induced currents, and the Cooper pair density, thereby opening new avenues for understanding superconductivity mechanisms.
High-pressure magnetotransport measurements on the topological semimetal YPtBi reveal that increasing pressure suppresses quantum oscillations and induces insulating behavior, indicating a weakening of band inversion and a tunable topological nature in this half-Heusler superconductor.
This study utilizes first-principles calculations to demonstrate that oxygen vacancies in amorphous AlO Josephson junction barriers enhance electrical conductivity and critical current noise, thereby accelerating superconducting qubit decoherence and informing radiation-hard device design.
This paper theoretically proposes that hole-doped reduced bilayer nickelate LaNiO can exhibit -wave superconductivity driven by interorbital interactions within an orbital-space bilayer model, where the absence of apical oxygens creates a large orbital energy offset analogous to interlayer hopping in bilayer systems.
This paper investigates a two-band system with momentum-dependent hybridization between a dispersive and a flat band, demonstrating that the interplay of interband mixing and intraband pairing can create parabolic nodes in the quasiparticle spectrum, leading to a quadratic temperature dependence of superconducting phase stiffness and revealing the system's sensitivity to nonmagnetic disorder through Machida-Shibata resonances.
Using vector magnetic field scanning tunneling microscopy, researchers discovered a previously unreported staggered charge density wave in UTe2 that is uniquely quenched by a modest field along the a-axis, simultaneously suppressing the Kondo resonance and revealing an orbital-selective hybridization mechanism that governs the material's intertwined electronic orders.
This study reports the discovery of a superconducting half-dome in compressively strained bilayer nickelate thin films, where continuous tuning of oxygen stoichiometry reveals a general phase diagram feature driven by the contrasting effects of interstitial oxygen doping and oxygen vacancy scattering.
This study demonstrates that superconducting LaPrNiO thin films exhibit a highly renormalized Fermi-liquid normal state characterized by resistivity and Kohler scaling, with a quasiparticle effective mass of approximately 10, thereby confirming their adherence to the universal scaling observed in strongly correlated superconductors.
