Using a SQUID microscope, researchers discovered that CsV3Sb5-xSnx kagome superconductors host a network of narrow supercurrent channels behaving as Josephson junctions, providing a spatial explanation for their anomalous transport properties and linking these phenomena to charge density waves and doping-induced disorder.
This paper investigates the transient suppression of on-dot electron pairing and its impact on subgap charge transport in a superconductor-quantum dot-normal metal junction when both dots are singly occupied by identical spins, providing temporal scales for these nonequilibrium triplet configurations that are relevant to superconducting qubit operations.
This paper introduces a quasi-one-dimensional Kitaev-like spin chain derived from a truncated honeycomb geometry that exhibits a topological phase transition between trivial and chiral phases, hosting protected zero-energy edge modes and fractionalized excitations that serve as experimental fingerprints of chiral topological order.
This study employs a multi-orbital itinerant framework to investigate magnetic ground states and spin excitations in bilayer and trilayer nickelates, demonstrating that calculated excitation spectra for specific stripe and spin-density-wave orders show strong qualitative agreement with experimental RIXS and neutron scattering data, thereby supporting a common itinerant origin of magnetism in these high- materials.
This paper presents a microscopic theory explaining the magnetic field-induced transition from nodeless s-wave to nodal p-wave superconductivity in -PdBi as a result of Zeeman splitting altering the pairing landscape and creating gapless excitations.
This study analyzes the spectral dynamics of frequency-modulated terahertz radiation from stacked intrinsic Josephson junctions in a cuprate superconductor, revealing a double-peak structure driven by electromagnetic coupling and quantifying a sub-nanosecond synchronization time that governs the system's non-equilibrium behavior.
This paper demonstrates the emergence of a nonclassical intermediate state in pristine three-dimensional superconductors where electric fields penetrate the system and coexist with superconductivity, driven by electric-field-induced order parameter fluctuations.
This paper demonstrates that supercurrent-driven spin accumulation in superconductor/magnetic insulator bilayers can efficiently control magnetic domain wall motion with significantly lower power dissipation than normal-state methods, offering a promising solution for cryogenic magnetic memory.
By tuning a terahertz cavity to resonate with specific phononic modes in few-layer niobium diselenide (NbSe2), researchers experimentally demonstrated for the first time that vacuum electromagnetic fluctuations can enhance superconductivity, increasing the transition temperature by approximately 10%.
This paper explores both artificially exfoliated van der Waals nanostructures and naturally occurring misfit layer superconductors as tunable bulk heterostructures that exhibit robust Ising superconductivity and potential topological states, offering significant promise for solid-state device applications.
