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 computes the pages of the momentum-space and real-space Atiyah-Hirzebruch spectral sequences for topological crystalline insulators and superconductors across 1651 magnetic space groups in up to three dimensions, enabling the determination of -groups for approximately 59% of these symmetry settings under a physically reasonable assumption.
This commentary paper refutes the claim that sulfur hydride (HS) exhibits high-temperature superconductivity via magnetic flux trapping, arguing that the experimental protocol used to generate the supporting time-dependent magnetic moment data is invalid and that an alternative protocol demonstrates the original evidence for vortex pinning is unfounded.
By employing a phenomenological symmetry-based method combined with DFT+ calculations, this study reveals that while both pressurized bulk and ambient-pressure thin-film exhibit -wave two-gap superconductivity, the significantly lower transition temperature in the thin film arises from a shift in dominant pairing from out-of-plane Ni- to in-plane Ni- orbitals driven by reduced inter-layer hopping.
This study demonstrates that the kagome superconductor CsV3Sb5 exhibits spontaneous time-reversal symmetry breaking in both its charge density wave and superconducting states, evidenced by nonreciprocal critical currents that can be deterministically trained by an external magnetic field.
This paper revises Landau theory by renormalizing quadratic coefficients to account for system dimensionality and intrinsic material parameters, thereby providing a phenomenological framework that quantitatively explains the diverse specific-heat jump behaviors observed in high-temperature superconductors through the inclusion of strong fluctuation corrections.
This review outlines the requirements and architectural strategies for integrating cryogenic electronics into fault-tolerant superconducting quantum computers, offering a first-order resource estimation framework to address the scaling challenges of classical control and readout systems.
By combining high-pressure and high-temperature Raman and infrared spectroscopies, this study establishes a unified picture of the tilt-free structural transition in LaNiO, revealing its strong coupling to a dramatic metallization and enhanced electron-phonon interaction that underpins the emergence of high-temperature superconductivity.
This paper demonstrates that material defects in tunnel junctions can create strongly coupled two-level systems (TLS) that interact with both transmon qubits and their readout resonators, causing frequency shifts that degrade readout fidelity and hinder the development of solid-state quantum processors.
This paper establishes a universal empirical scaling relation between microwave dissipation and superfluid density across diverse superconducting materials and geometries, revealing an intrinsic bulk dissipation limit caused by nonequilibrium quasiparticles trapped in disorder-induced gap variations that sets a fundamental bound on superconducting qubit coherence.
This study employs the quasiclassical Eilenberger formalism to demonstrate that noncentrosymmetric superconductors with Rashba spin-orbit coupling and in-plane magnetic fields exhibit tunable superconducting and Josephson diode effects, wherein the emergence of Bogoliubov Fermi surfaces at the Lifshitz transition not only maximizes diode efficiency but also induces a strong current anisotropy that serves as a novel detection method for these exotic states.
