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 reveals that in the Janus MXene Mo2NF2, a charge density wave instability driven by momentum-dependent electron-phonon coupling competes with superconductivity, but the latter can be enhanced and the former suppressed through compressive biaxial strain, thereby establishing Mo2NF2 as a tunable platform for controlling the interplay between these two quantum phases.
This study demonstrates through simulations and *ab initio* calculations that stacking two-dimensional van der Waals materials can induce a robust, high-temperature inter-layer s-wave superconductivity driven by a strong-coupling Kohn-Luttinger mechanism, where pairing attraction scales linearly with inter-layer repulsion rather than quadratically.
This study demonstrates that controllably introducing disorder via iron cluster deposition in monolayer Fe(Te,Se) drives a superconductor-insulator transition, revealing a disorder-induced quantum phase transition characterized by the evolution from superconducting to insulating U-shaped gaps attributed to localization-enhanced Cooper pair correlations.
This paper demonstrates that weakly coupled altermagnetic Josephson junctions host spin-polarized Andreev molecules, which induce anomalous nonlocal Josephson effects including tunable phase transitions and a nonreciprocal diode effect, thereby establishing altermagnetism as a promising platform for nonlocal spin Josephson phenomena.
This paper presents a systematic study of few-layer -MoTe that correlates superconducting properties with material parameters and band structure, revealing that highly hole-doped bilayer samples exhibit conventional phonon-mediated -wave pairing.
This paper presents a parameter-free, first-principles framework based on superconducting density functional theory to simultaneously calculate the coherence length, penetration depth, and transition temperature of superconductors, successfully validating the method against experimental data and providing a microscopic explanation for the Uemura plot's empirical correlations.
This study utilizes time-dependent Ginzburg-Landau simulations to reveal how inhomogeneous magnetic fields from ferromagnetic nanodots drive the nucleation, creep-like deformation, and formation of unique stationary configurations of Abrikosov vortices in hybrid superconductor-ferromagnetic nanostructures, offering critical insights for optimizing nanoscale superconducting systems.
Using sign-problem-free determinant quantum Monte Carlo simulations, this study demonstrates that introducing next-nearest-neighbor hopping in the attractive Hubbard model on a square lattice can significantly enhance the critical temperature by up to 50% while simultaneously reducing the pseudogap region, offering a viable route to achieve experimentally accessible superconducting temperatures.
This study reports the discovery of an unprecedented time-reversal symmetry breaking superconducting state accompanied by electronic glass dynamics in epitaxially strained (La, Pr, Sm)₃Ni₂O₇ bilayer nickelate films, evidenced by unconventional magnetoresistance hysteresis, zero-field non-reciprocity, and logarithmically slow resistance relaxations.
This study establishes a systematic gigantic-oxidative atomic-layer-by-layer epitaxy approach to grow phase-pure, high-quality Ln3Ni2O7 thin films that exhibit superconductivity with an onset transition temperature of 50 K without post-annealing, while identifying four critical factors—precise cation stoichiometry, complete atomic layer coverage, optimized interface reconstruction, and accurate oxygen content regulation—that govern their crystalline quality and superconducting properties.
