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 investigates the interacting Su-Schrieffer-Heeger model with extended-range hoppings, revealing a rich ground-state phase diagram comprising topological, superconducting-like, and charge-density-wave phases, and derives order parameters that demonstrate how interactions enable non-unidirectional hoppings distinct from the non-interacting case.
The paper predicts a fundamentally new superconducting state called proximity-induced orbital antiferromagnetism in Ising superconductor/antiferromagnet heterostructures, where a periodic phase modulation generates atomic-scale loop currents with opposite orbital moments, a phenomenon demonstrated via NbSe/MnPS calculations to be robust and distinct from existing FFLO or helical states.
This study reveals that three-dimensional superconducting altermagnets host topologically protected crossed surface flat bands and Bogoliubov-Fermi surfaces arising from the interplay of superconducting and altermagnetic symmetries, which manifest as distinct charge conductance signatures for experimental detection.
This paper proposes a nonlinear extension of the Madelung transformation using a hyperbolic phase-amplitude coupling to derive amplitude-dependent quantum hydrodynamics that modifies the continuity and force equations, ultimately leading to density-gradient-sensitive corrections in the London equations and Meissner effect.
This paper predicts that flat-band superconductors can sustain a stable phase of magnetic flux walls under applied magnetic fields, a phenomenon driven by the unique periodic free energy of flat bands that allows for the formation of kink and breather solitons and potentially enhances superconductivity in high-field environments.
This paper introduces scalable quantum algorithms that combine arbitrary BCS state preparation with amplitude amplification to achieve a quadratic reduction in projection queries, enabling the efficient preparation of Gutzwiller-projected states for simulating strongly correlated lattice models like the - model.
This paper presents realistic calculations demonstrating that interlayer "dynamical singlets" formed between and orbitals govern the physics of bilayer nickelates, successfully explaining experimental discrepancies between bulk crystals and thin films through their distinct responses to hydrostatic pressure and epitaxial strain.
This paper argues that assuming a "discrete" vacuum geometry in the Minkowskian Higgs model justifies Dirac fundamental quantization by introducing thread-like topological defects that generate collective solid rotations, leading to a first-order phase transition characterized by the coexistence of rotational and superfluid thermodynamic phases within BPS monopole vacua.
This paper presents a breakthrough in superconducting electronics by demonstrating a voltage-controlled, non-volatile memory device that combines gate-controlled supercurrent suppression with charge trapping in an AlO dielectric to achieve stable binary storage, reliable read/write cycling, and thermal resilience surpassing all existing superconducting memories.
This paper investigates the role of soft transverse optic phonons in driving superconductivity within KTaO3 heterostructures, finding that while this mechanism successfully explains the observed interface orientation dependence and anisotropic gap, it requires augmentation from other phonon modes to account for the experimentally measured transition temperatures.
