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 paper demonstrates that Majorana bound states in a topological superconductor coupled to a photonic cavity persist at finite, tunable energies with enhanced stability and disorder resilience, while introducing a modified spectral localizer formalism to characterize these cavity-induced topological features across different photon sectors.
By incorporating nuclear quantum many-body effects into first-principles calculations, this study reveals that a lattice quantum disordered phase in H3S and La3Ni2O7 serves as the origin and key ingredient of unconventional superconductivity, offering a unifying framework for understanding high-temperature superconductivity beyond traditional electronic models.
By combining high-resolution angle-resolved photoemission spectroscopy with theoretical calculations, this study reveals that geometric frustration of interorbital hybridization in Pr4Ni3O10 drives an orbital-selective Mott phase characterized by incoherent flat bands and coherent dispersive bands, offering a structural control parameter for understanding correlated states and superconductivity in trilayer nickelates.
This paper presents a unified category-theoretic framework that describes the transition between quantum Hall hierarchy states and anyon superconductivity through a generalized stack-and-condense procedure, successfully reproducing known phases and predicting novel charge-$ke$ anyon superconductors derived from fractional quantum Hall states.
This paper predicts distinct optical signatures, specifically diagonal conductivity anisotropy for nematic states and finite optical Hall conductivity for chiral states, to experimentally distinguish between the two-component pairing ground states in transition metal dichalcogenide superconductors.
This study provides experimental evidence for coexisting topological hinge states and 1D Rashba states in BiSb nanoflakes through Josephson effect measurements, identifying the material as a prototypical second-order topological insulator platform.
By directly applying three types of shear strain to Sr2RuO4 single crystals and observing negligible changes in the superconducting transition temperature, this study provides evidence that shear strain does not couple to superconductivity, supporting a one-component order parameter model while highlighting its inability to fully explain other experimental anomalies.
By employing path integral molecular dynamics with a machine-learned potential, this study reveals that the high-temperature superconductivity in HS occurs in a paraelectric region dominated by large nuclear quantum fluctuations above a ferroelectric quantum critical point at approximately 134 GPa, which belongs to the 4D Ising universality class.
By employing micro-focused angle-resolved photoemission spectroscopy on single-domain PrNiO, this study resolves intrinsic electronic features obscured by material inhomogeneity to demonstrate that unidirectional density wave formation is driven by inter-orbital nesting between and bands, while simultaneously quantifying the orbital-dependent gap and revealing the intrinsic trilayer -band splitting.
Using polarization-resolved electronic Raman scattering, this study reveals that the spin-density-wave gap in trilayer La4Ni3O10 opens on both and pockets with a distinct momentum-space topology that contrasts sharply with the -pocket-only gap observed in bilayer La3Ni2O7, thereby providing new constraints on the microscopic mechanisms driving density-wave instabilities in layered nickelates.
