Fluxon Dynamics of a Long Josephson Junction with Two-gap Superconductors
Ju H. Kim, Bal-Ram Ghimire, Hao-Yu Tsai
We investigate the phase dynamics of a long Josephson junction (LJJ) with two-gap superconductors. In this junction, two channels for tunneling between the adjacent superconductor…
Effects of Resonant Cavity on Macroscopic Quantum Tunneling of Fluxon in Long Josephson Junctions
Ju H. Kim, Ramesh P. Dhungana
We investigate the effects of high-Q_c resonant cavity on macroscopic quantum tunneling (MQT) of fluxon both from a metastable state to continuum and from one degenerate ground-sta…
Decoherence in Josephson vortex quantum bits
Ju H. Kim, Ramesh P. Dhungana, Kee-Su Park
We investigated decoherence of a Josephson vortex quantum bit (qubit) in dissipative and noisy environment. As the Josephson vortex qubit (JVQ) is fabricated by using a long Joseph…
Collective Josephson Vortex Dynamics in Long Josephson Junction Stacks
Ju H. Kim, J. Pokharel
We investigate the collective phase dynamics in conventional long Josephson junction (LJJ) stacks and in layered superconductors, exhibiting intrinsic LJJ behaviors. Using a theore…
