Tunneling of a Quantized Vortex: Roles of Pinning and Dissipation
Ping Ao, David J. Thouless
We have performed a theoretical study of the effects of pinning potential and dissipation on vortex tunneling in superconductors. Analytical results are obtained in various limits…
Topological Landau-Ginzburg Theory for Vortices in Superfluid He
M. Hatsuda, S. Yahikozawa, P. Ao +1
We propose a new Landau-Ginzburg theory for arbitrarily shaped vortex strings in superfluid He. The theory contains a topological term and directly describes vortex dynamics. W…
Escape of trapped electrons from a helium surface: a dynamical theory
Ping Ao
We present a dynamical theory which incorporates the electron-electron correlations and the effects of external magnetic fields for an electron escaping from a helium surface. Anal…
Implications of adiabatic phases for a vortex in a superconductor film
Ping Ao, Qian Niu, David J. Thouless
Based on ideas of off-diagonal long range order and two-fluid model, we demonstrate that adiabatic phases for a slow motion of a vortex in a superconductor film give rise naturally…
Dynamical Correlation Theory for an Escape Process
Ping Ao
A dynamical theory which incorporates the electron-electron correlations and the effects of external magnetic fields for an electron escaping from a helium surface is presented. Th…
