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 demonstrates that stacking misfit layered chalcogenides with 1H-TaS induces anisotropic symmetry breaking in the charge-density wave state through a nonlinear coupling with the uniaxial moiré potential, while leaving the material's s-wave superconductivity largely unaffected.
This study presents a first-principles analysis of the multiband superconductor BeAu, revealing its complex Fermi surface topology with high-Chern-number Weyl points and surface Fermi arcs, which supports a topological superconducting phase and potentially explains its multigap behavior.
This paper utilizes Ginzburg-Landau theory to demonstrate that the coexistence of -wave altermagnetism and superconductivity in thin films produces characteristic fourfold anisotropies in critical temperature, parallel critical field, and critical current density, providing experimentally accessible signatures for detecting altermagnetism.
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 paper investigates how multi-mode interactions in driven Josephson junction chain cavities degrade internal coherence and shape steady states, revealing that while non-resonant processes dominate equilibrium decay, weak driving enhances resonant scattering to produce observable linewidth signatures and a distinct non-equilibrium steady state.
This paper reports the discovery of pressure-induced band gap widening in carbon-chain-filled KFI zeolite and the synthesis of ultra-long cumulene chains within this framework, which exhibit a record-breaking superconducting transition temperature of approximately 62 K, offering new pathways for high-pressure semiconducting electronics and high-temperature superconductivity.
This paper presents a method using Rydberg atom processors and sample-based quantum diagonalization to calculate the ground state energy of the Fermi-Hubbard model for large U by sampling the Heisenberg model, demonstrating superior convergence and efficiency over random sampling on up to 56 qubits while analyzing the potential for studying emergent superconductivity.
This paper establishes a unified framework for electron- and phonon-driven superconductivity in twisted bilayer graphene, revealing that momentum-space frustration of locally preferred nematic orders can stabilize a chiral ground state with unpaired flat bands at large fillings or weak interactions.
Using a parquet renormalization group analysis on a Rashba model with higher-order van Hove singularities, this study demonstrates that the interplay between nontrivial Berry phases and electronic interactions robustly stabilizes chiral topological superconductivity despite competing fluctuations.
This paper demonstrates that the saddle-point configuration for thermal phase slips in an infinite superconducting film near the critical current is exactly solvable via the Boussinesq equation, revealing specific scaling laws for the instanton size and activation energy that explain the behavior of superconducting strips used in photon detection.
