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 revisits interacting 3D electron gases in strong magnetic fields to demonstrate that generalized interactions and symmetry breaking can stabilize nematic charge density waves and catalyze a novel layered Weyl superconducting state, thereby expanding the understanding of non-Fermi liquid stability and field-resistant superconductivity in high-field regimes.
This study demonstrates that mechanically stable, bromine- and iodine-functionalized Mo2C MXene monolayers exhibit significantly enhanced and tunable phonon-mediated superconductivity, with transition temperatures reaching up to 21.7 K under electron doping, driven by strong electron-phonon coupling facilitated by halogen functionalization.
The paper demonstrates that the c-axis stacking sequences in TaSe2 polytypes (1T, 2H, and 3R) critically modulate interlayer coupling and coordination, thereby dictating the distinct charge density wave orders and varying degrees of superconductivity observed in each phase.
By coupling BCS theory to an external gravitomagnetic vector potential, this paper identifies a quantum-geometric contribution to the thermal conductivity of superconductors and establishes Wiedemann-Franz-type bounds relating thermal and electric Meissner stiffnesses to the quantum metric and Chern number.
Using leading-order chiral perturbation theory, this paper maps the low-energy QCD phase diagram under magnetic fields with baryon and isospin chemical potentials, identifying various exotic phases including a chiral soliton lattice and a hybrid vortex phase that may be relevant to neutron stars at magnetic fields around G.
This study investigates how lattice termination, spin-orbit coupling, and magnetic order collectively govern the emergence and tunability of edge states in a two-dimensional kagome lattice, revealing a transition from termination-sensitive localized modes to robust topological phases such as insulators and Chern insulators.
By employing a gate-defined, radio frequency-biased Josephson junction to probe quasiparticle and condensate dynamics in magic-angle twisted bilayer graphene, this study recovers the evolution of thermalization rates and superfluid stiffness across the phase diagram, providing evidence for an anisotropic or nodal pairing state and a method to estimate electron-phonon coupling strength.
This paper presents a first-principles-based microscopic theory that calculates electron-phonon coupling in twisted bilayer graphene for arbitrary twist angles without periodic supercells, revealing that the coupling is strongly enhanced near the magic angle due to a resonance between electronic bandwidth and phonon frequencies, thereby predicting superconductivity up to .
This study utilizes a three-orbital model to demonstrate how Fermi surface geometry, Van Hove singularities, and inter-orbital charge transfer in SrRuO critically influence optical Hall response and the polar Kerr effect, identifying specific pairing symmetries and Lifshitz transitions as key drivers of these phenomena.
This paper proposes and validates through tensor network simulations a microscopic mechanism for anyon superconductivity in fractional Chern insulators, demonstrating that repulsive interactions can drive a transition to a semion crystal state where the energetic preference for binding anyons into charge-2e pairs leads to robust superconductivity upon doping.
