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 experimentally demonstrates Josephson diode and spin-valve effects in In-CrSb-In junctions and FFLO-like behavior in single In-CrSb interfaces, attributing these phenomena to the interplay between spin-polarized topological surface states and bulk altermagnetic spin splitting in CrSb.
Using variational Monte Carlo simulations on a bilayer two-orbital Hubbard model, this study reveals that the high-temperature superconductivity in LaNiO arises from a hierarchical pairing structure where the primary interaction stems from Ni orbital splitting, while orbital hybridization redistributes these correlations to the channel, thereby reconciling competing theoretical scenarios and explaining the robustness of the state.
This study reports the high-pressure synthesis of cubic BaSiH that remains stable at ambient conditions, exhibiting superconductivity at 142 GPa and unique semiconductor-like properties with persistent X-ray photoconductivity at lower pressures, thereby overcoming a critical bottleneck in superhydride chemistry for potential hydrogen storage applications.
By applying in-plane uniaxial stress to LaBaCuO at the 1/8 doping level, researchers suppressed the competing LTT phase and static spin-stripe order volume, thereby unlocking a giant enhancement of bulk superconductivity with a transition temperature reaching 46 K, which reveals that while static stripes hinder phase coherence, stripe-related interactions actually strengthen the underlying pairing mechanism.
This paper demonstrates that quantum interference at extended superconducting interfaces breaks the expected bias symmetry of transport by causing unequal phase accumulation for electrons and holes, thereby creating a bias-asymmetric conductance that serves as a spectroscopic probe of nonlocal interface physics and superconducting energy scales.
This paper provides a unified theoretical understanding of experimental variations in bilayer nickelates under diverse conditions—such as pressure, strain, rare-earth substitution, and hole doping—by employing a strong-coupling model that successfully reproduces observed trends and suggests electron doping or increased compressive strain as pathways to further enhance superconductivity.
This study employs coplanar superconducting resonators to probe magnetic excitations in epitaxial TbInO3 thin films, revealing extreme magnetic frustration down to 20 mK and elucidating the complex interplay of spin-orbit coupling, crystal fields, and improper ferroelectricity that shapes its quantum spin liquid candidate ground state.
By utilizing symmetry-resolved elastoresistivity and elastocaloric measurements, this study resolves the controversy regarding the charge density wave in 1T-TiSe by identifying it as a centrosymmetric ferroaxial state that precedes a distinct nematic transition, thereby reconciling conflicting surface-sensitive observations with bulk symmetry constraints.
Using wide-field quantum microscopy, this study reveals that the superconducting transition temperature of optimally doped Bi-2223 single crystals remains robust up to 23 GPa in KBr but vanishes above 11 GPa in cBN, demonstrating the material's extreme sensitivity to the hydrostaticity of the pressure-transmitting medium.
This paper corrects the misconception that odd-parity magnets preserve time-reversal symmetry by revealing a hidden Zeeman field that, when combined with their large non-relativistic spin splitting, creates an ideal platform for realizing robust, field-free topological superconductors with distinct Majorana boundary modes.
