The paper demonstrates that in disordered superconductors, a dc supercurrent causes a dramatic, parametric enhancement of the coupling between two-level systems and external ac electric fields, leading to increased ac conductivity and 1/f noise in equilibrium current fluctuations.
This paper proposes a "Q-ball" mechanism for high- superconductivity, where nontopological solitons formed by condensed spin/charge density wave fluctuations explain key phenomena in cuprates, including linear-in-temperature resistivity, the pseudogap phase, the superconducting dome, and the hourglass spin excitation dispersion.
The study demonstrates that Eu-doped infinite-layer nickelates exhibit a magnetic-field-induced re-entrant superconducting phase in the over-doped regime, providing a new platform for exploring the interplay between magnetism and high-temperature superconductivity.
Scanning SQUID imaging of the weak type-II superconductor reveals dense vortex clusters with unique boundary and internal dynamics that defy standard single-band models, suggesting new physics regarding non-monotonic vortex interactions.
Using a tunnel diode resonator to measure the Campbell penetration depth in , the researchers discovered anomalous magnetic field and temperature dependencies that provide new evidence for vortex lattice symmetry changes and unconventional superconductivity in this heavy fermion material.
This paper demonstrates that anisotropic coupling between spin-triplet pairing correlations in Josephson junction networks can create frustrated -vector textures, leading to the spontaneous trapping of nonintegral (fractional) magnetic flux.
This paper demonstrates a scalable, non-volatile superconducting memory device that uses exchange-field gap engineering in a vertical spin-valve architecture to achieve low-power, high-efficiency magnetoresistance for cryogenic and quantum computing applications.
This paper uses first-principles calculations to theoretically predict that a hypothetical cubic phase of could exhibit strong-coupling superconductivity with a critical temperature of up to 73.7 K at ambient pressure.
This paper proposes a theoretical framework for realizing robust, tunable Majorana bound states at the corners of a two-dimensional semi-Dirac system by inducing effective p-wave pairing in its anisotropic edge states through the interplay of Rashba spin-orbit coupling, a Zeeman field, and s-wave superconductivity.
This paper describes the development and upgrading of a specialized measurement setup at DESY designed to investigate the superconducting properties of niobium cavities by analyzing resonance frequency shifts and quality factor changes during the transition from a superconducting to a normal-conducting state.
