Magnetic flux quanta in Josephson junctions, often called fluxons, in many cases behave as
solitons. A review of recent experiments and modelling of fluxon dynamics in Josephson …

Vortices occur naturally in a wide range of gases and fluids, from macroscopic to
microscopic scales. In Bose–Einstein condensates of dilute atomic gases, superfluid helium …

(57) ABSTRACT A Superconducting qubit is presented. The qubit is a shaped long
Josephson junction with a magnetic fluxon Such that, in the presence of an externally …

The interaction of a Josephson fluxon with an externalmagnetic field-induced potential in a
long Josephson junctionis investigated experimentally. The thermal activation of thefluxon …

Rotational analogs to magnetic fluxons in conventional Josephson junctions are predicted to
emerge in the ground state of rotating tunnel-coupled annular Bose-Einstein condensates …

We theoretically investigate the macroscopic quantum dynamics of a π junction with a
superconductor (S) and a multiferroic material or a ferromagnetic insulator (FI). By deriving …

We present a quantitative study of the current-voltage characteristics (CVC) of diffusive
superconductor/insulator/ferromagnet/superconductor (SIFS) tunnel Josephson junctions. In …

We study macroscopic quantum tunneling (MQT) in c-axis twist Josephson junctions made
of high-T c superconductors in order to clarify the influence of the anisotropic order …

The thermal and the quantum dissociation of a single vortex-antivortex (VAV) pair in an
annular Josephson junction is experimentally observed and theoretically analyzed. In our …

We study fluxon tunneling both across one microshort-type barrier and resonant tunneling
across two barriers. We have derived an effective Hamiltonian (using the inverse scattering …
