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 provides experimental evidence for intrinsic, spin-polarized superconductivity in mesoscopic Fe(Te,Se) rings, characterized by a current-dependent magnetic field and dual flux quantization that is explained by a model combining Rashba coupling with anisotropic out-of-plane interactions.
This paper demonstrates that a temporal Berry phase in a clean U(1) nonlinear sigma model induces space-time anisotropic vortex interference, leading to a quasi-disordered phase with short-range spatial order and persistent temporal coherence that shares the essential correlation properties of the disordered Bose Glass phase, thereby suggesting a unified topological origin for glassy behavior in phase-fluctuation-driven superfluid transitions.
This paper demonstrates that the transition between and superconducting states in a two-band model with nonmagnetic impurities evolves from a smooth crossover at high temperatures to a first-order phase transition at low temperatures, thereby establishing a critical end point on the temperature-impurity scattering rate phase diagram that suggests the possibility of a quantum phase transition.
This paper demonstrates that incoherent electronic spectra across diverse strongly correlated materials arise from self-generated dynamical disorder and collapse onto a single universal curve described by a parabolic cylinder function, revealing a marginal dynamical regime where microscopic details become irrelevant at low energies.
This paper employs Monte Carlo simulations of a U(1) lattice gauge system to demonstrate that the thermal phase transition of a superconductor belongs to the XY universality class, exhibiting critical exponents consistent with Bose-Einstein condensation and neutral boson transitions.
Using numerically exact diagrammatic Monte Carlo simulations, this study demonstrates that while long-range Coulomb repulsion suppresses the superfluid transition temperature of bond bipolarons in a two-dimensional Su--Schrieffer--Heeger model, a significant remains achievable across a broad parameter range, including the adiabatic regime.
This paper proposes a superconducting spatiotemporal metasurface that achieves one-way nonreciprocal absorption through a classical analogue of photon blockade, where forward waves are resonantly absorbed via harmonic conversion while backward waves transmit freely, offering a promising pathway for compact quantum information devices.
This paper proposes that heterosheared bilayer graphene hosts high-temperature superconductivity driven by 1D moiré flat bands, where valley polarization enables Cooper pair condensation by spatially separating electrons of opposite spins to minimize Coulomb repulsion.
This study demonstrates that epitaxial growth of monolayer NbSe on graphite naturally forms moir{é} superlattices where interlayer coupling between graphite states and NbSe suppresses charge-density wave enhancement, offering a new pathway for controlling collective states in 2D materials without manual assembly.
This paper introduces a cryogenic widefield NV-diamond microscope that enables rapid, micrometer-scale imaging of magnetic flux trapping in superconducting devices, revealing critical vortex expulsion behaviors in Nb thin films and offering a high-throughput tool for improving the reliability of scalable superconducting electronics.
