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 presents a comprehensive topological phase diagram for a two-dimensional electron gas in a magnetic field proximitized by a superconducting vortex lattice, revealing that Landau-level mixing and weak pairing induce a complex sequence of topological superconducting phases with varying Chern numbers and chiral edge modes.
Using machine learning, this study reveals a strong correlation between the normal-state resistivity of Fe-based superconductors and their superconducting properties, identifying predictive signatures in a high-temperature window (150–300 K) far above the critical temperature that involve multiple scattering channels.
The paper proposes that room-temperature superconductivity in micron-sized hydride samples under extreme pressure can be achieved by minimizing both the metal probe barrier width and the sample thickness to optimize macroscopic quantum tunnelling.
This paper introduces a novel ultrafast spectroscopy platform capable of simultaneous high pressure (up to 40 GPa) and high magnetic field (up to 7 T) to investigate the trilayer nickelate , revealing that while pressure suppresses charge-density-wave order and induces incipient superconducting correlations, the lack of magnetic field dependence suggests any resulting superconducting state is non-bulk and inhomogeneous rather than a true bulk phase.
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 paper theoretically investigates the anisotropic superconducting diode effect in planar Josephson junctions with coexisting Rashba and Dresselhaus spin-orbit couplings, revealing how magnetic and crystalline orientations, electrostatic gating, and SOC-induced Fermi surface distortions govern the diode efficiency and polarity reversals.
This paper presents a unified Green's-function theory demonstrating how charge-density-wave fluctuations attenuate acoustic phonons through distinct local-intensity and texture scattering channels, successfully explaining experimental observations of phonon softening and anomalous thermal transport in various correlated materials like 2H-TaSe.
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.
