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.

By extending high-field measurements up to 45 T in a high-quality UTe sample, this study provides direct evidence that the SC3 superconducting phase spills outside the spin-polarized state, supporting the scenario that its pairing is mediated by quantum critical fluctuations.
This paper argues that the superconducting volume fraction in pressurized Ruddlesden-Popper nickelates has been nearly twofold overestimated due to an incorrect calculation procedure and equation used in recent studies, which affects all previously reported values for these materials.
The paper demonstrates that standard one-band d-wave Eliashberg theory, driven by antiferromagnetic spin fluctuations, successfully reproduces the critical temperature and superconducting gap of overdoped Bi2Sr2CaCu2O8+d using only a single free parameter.
This paper demonstrates that a one-band d-wave Eliashberg theory, mediated by antiferromagnetic spin fluctuations with a characteristic energy scaling linearly with Tc, successfully describes overdoped high-Tc superconductors by establishing universal relationships between the s and d components of electron-boson coupling constants and the invariance of the 2Δ/kBTc ratio.
This study provides first-principles evidence that high-temperature superconductivity in LaNiO is driven by structural variations under hydrostatic pressure that enhance electronic correlations through an interplay of orbital localization and competing screening channels, a mechanism further validated by finite-temperature simulations and comparative analysis with AcNiO.
This paper presents a self-consistent theoretical framework using the Bogoliubov-de Gennes Hamiltonian and Kubo formula to analyze how Zeeman fields and Rashba spin-orbit coupling jointly influence the spin susceptibility of -wave and -wave superconductors, providing quantitative benchmarks for identifying pairing symmetries and interaction strengths in non-centrosymmetric materials.
This study demonstrates that cryogenic scanning nitrogen vacancy magnetometry serves as a reliable, high-resolution quantitative tool for imaging Abrikosov vortex lattices in high- superconductors like BSCCO-2212 and YBCO, successfully revealing distinct ordering behaviors and confirming flux quantization within short acquisition times.
This study demonstrates that the superconducting diode effect in patterned niobium films can be engineered through macroscopic asymmetric antidots by leveraging distinct edge and bulk flux pinning mechanisms under in-plane and out-of-plane magnetic fields, respectively, to provide a unified design principle for tunable nonreciprocal quantum circuits.
This study demonstrates that uniaxial strain acts as a sensitive probe in FeSe, revealing that ordering fluctuations near the nematic transition enhance electron-phonon coupling and induce a distinct two-phonon scattering anomaly in the mode, which is highly dependent on the direction and magnitude of the applied strain.
This paper theoretically demonstrates that Rashba spin-orbit coupling in altermagnet/triplet superconductor/altermagnet junctions enables a robust, electrically tunable spin valve effect and distinct transport signatures that distinguish between nodal and chiral triplet pairing symmetries, all without requiring ferromagnetic electrodes.
