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.

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 demonstrates that in superconducting wallpaper fermions protected by symmetry, the hybridization between wallpaper fermions and Majorana Kramers pairs in the representation generates a unique double-twisted surface state with four density-of-states peaks and mirror-helicity-free characteristics, distinguishing it from other known superconducting topological insulators.
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.
A muon-spin rotation study of the trilayer nickelate PrNiO reveals three distinct magnetic transitions at ambient pressure, including a weakly first-order spin-density-wave ordering at 158 K, and demonstrates that hydrostatic pressure linearly suppresses both the ordering temperature and the magnetic moment, indicating a gradual weakening of the magnetic instability.
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.
By fabricating SQUIDs from twisted interfaces, researchers detected a phase shift and time-reversal symmetry breaking indicative of chiral superconducting order, while also demonstrating high-temperature flux sensing capabilities that open new avenues for studying unconventional superconductivity.
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.
Using density-matrix renormalization group simulations on a two-leg ladder, this study reveals that hole doping in the Kitaev-Heisenberg model exhibits strong kinetic obstruction to pairing at high hopping strengths while establishing a doping-dependent phase diagram where superconducting, charge-density-wave, and spin-density-wave correlations dominate in distinct regimes defined by the interplay of kinetic energy and magnetic interactions.
