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 proposes a method to isolate and detect nonequilibrium Cooper quartets in a double-quantum-dot system by demonstrating that high-bias voltage driving induces a resonant two-Cooper-pair exchange process, which yields distinctive transport signatures such as a bias-dependent Andreev current peak and equal auto- and cross-correlations.
This paper demonstrates that the gene principle and collaborative Fermi-surface rule unify the mechanism of high- superconductivity in bilayer nickelate LaNiO, where cooperative interlayer and intralayer antiferromagnetic exchange channels drive a robust pairing state with internal sign reversal.
This study utilizes ac magnetostriction to reveal the collective oscillations of superconducting/normal domain walls in type-I lead superconductors, a distinct bulk dynamic process driven by eddy currents that remains obscured in conventional magnetic measurements.
This study utilizes density functional theory to demonstrate that metal atom disorder and specific equimolar doping in high-pressure YCaH superhydrides significantly influence structural stability and can either enhance or drastically reduce superconducting critical temperatures, with YCaH achieving a peak of 170 K at 180 GPa.
This paper demonstrates that a three-dimensional Kondo lattice model with non-Abelian SU(2) order parameters supports a Bose metal phase characterized by electron-Majorana bound states and a resistivity scaling, which emerges between uniform superconducting and pair-density-wave phases due to anomalously strong fluctuations driven by a vanishing superconducting stiffness and an enlarged order-parameter manifold.
Using variational exact diagonalization on the Hubbard-Holstein model, this paper demonstrates that two-electron angle-resolved photoemission spectroscopy (2eARPES) can identify preformed electron pairs through distinct energy and momentum signatures, thereby confirming their existence and distinguishing between coherent superconducting and incoherent pairing states.
This paper presents a digital predistortion framework using IIR and FIR filters to characterize and compensate for flux-control signal distortions in superconducting qubits, thereby enabling automated rapid calibration and significantly improving gate fidelity on quantum processing units.
This paper proposes a theoretical framework demonstrating that the phase of a stripe charge density wave can control the topological state of a magnetic vortex, particularly through an inversion-symmetry-breaking mechanism that induces a robust transition by enabling spin-triplet pairing.
This paper demonstrates that in line-graph lattices with strong attractive interactions, doped charges form obstructed Cooper pairs whose motion is frustrated by destructive interference, causing the pair kinetic energy to vanish and resulting in a disorder-free, interaction-driven localization that yields an exact spin liquid ground state with topological order.
This paper proposes a theoretical framework for a two-dimensional ferromagnetic superconductor where an attractive interaction between Skyrmions and vortices leads to the formation of bound pairs, resulting in a novel "vortex-drag induced Skyrmion Hall effect" where a Magnus force on the vortex drives a transverse drift of the Skyrmion.
