This study utilizes time-dependent Ginzburg-Landau simulations to reveal how inhomogeneous magnetic fields from ferromagnetic nanodots drive the nucleation, creep-like deformation, and formation of unique stationary configurations of Abrikosov vortices in hybrid superconductor-ferromagnetic nanostructures, offering critical insights for optimizing nanoscale superconducting systems.
This paper theoretically demonstrates the emergence of Majorana flat bands in the vortex lines of superconducting time-reversal-symmetry-breaking Weyl semimetals by decomposing the system into -resolved Chern insulators, identifying the conditions for their formation, proposing a -resolved Chern-Simons invariant for their characterization, and confirming their realization via attractive Hubbard interactions.
Using sign-problem-free determinant quantum Monte Carlo simulations, this study demonstrates that introducing next-nearest-neighbor hopping in the attractive Hubbard model on a square lattice can significantly enhance the critical temperature by up to 50% while simultaneously reducing the pseudogap region, offering a viable route to achieve experimentally accessible superconducting temperatures.
This paper reports transport studies of hybrid InAs nanowire Josephson junctions with epitaxial EuS and Al shells, demonstrating proximity-induced spin-split superconductivity and establishing a new platform for exploring spin-triplet pairing driven by spin-orbit coupling.
This study reports the discovery of an unprecedented time-reversal symmetry breaking superconducting state accompanied by electronic glass dynamics in epitaxially strained (La, Pr, Sm)₃Ni₂O₇ bilayer nickelate films, evidenced by unconventional magnetoresistance hysteresis, zero-field non-reciprocity, and logarithmically slow resistance relaxations.
This study establishes a systematic gigantic-oxidative atomic-layer-by-layer epitaxy approach to grow phase-pure, high-quality Ln3Ni2O7 thin films that exhibit superconductivity with an onset transition temperature of 50 K without post-annealing, while identifying four critical factors—precise cation stoichiometry, complete atomic layer coverage, optimized interface reconstruction, and accurate oxygen content regulation—that govern their crystalline quality and superconducting properties.
This paper reports the fabrication of boron-doped, ultra-thin carbon nanotube networks within zeolite pores that exhibit characteristic signatures of high-temperature superconductivity with a critical temperature between 220 and 250 K, alongside a giant pressure effect that further elevates this transition temperature.
This paper investigates the phase diagram of a periodically driven O(N) scalar field theory coupled to a thermal bath, revealing diverse symmetry-broken states and novel electromagnetic responses such as the Meissner effect, a hybrid "Meissner polariton" mode, and superconducting-like behavior driven by fluctuations.
This paper presents theoretical and experimental evidence for a new phase of matter called multimodal superfluidity in neutron-rich systems, characterized by the coexistence of s-wave pairs, p-wave entangled double pairs, and quartets, which is predicted to occur in various fermionic systems and has significant implications for the structure and dynamics of neutron star crusts.
This paper demonstrates that depositing granular aluminum on Ge/SiGe heterostructures induces a hard superconducting gap with exceptional magnetic field resilience, enabling the observation of Zeeman-split Yu-Shiba-Rusinov states and tunable g-tensors essential for hole spin-based hybrid quantum devices.
