Berry Phase and Dissipation of Topological Singularities
Ping Ao, Xiao-Mei Zhu
We outline a path integral derivation of both the transverse force, the Berry phase, and friction for a vortex from the microscopic fermionic superfluid theory. The derivation mani…
Nonholonomic approach to rotating matter in general relativity
Mattias Marklund, Gyula Fodor, Zoltán Perjés
Rigidly rotating stationary matter in general relativity has been investigated by Kramer by the Ernst coordinate method. A weakness of this approach is that the Ernst potential doe…
Critical Behavior of the Meissner Transition in the Lattice London Superconductor
Peter Olsson, S. Teitel
We carry out Monte Carlo simulations of the three dimensional (3D) lattice London superconductor in zero applied magnetic field, making a detailed finite size scaling analysis of t…
Quantized Vortices in Superfluids and Superconductors
D. J. Thouless, Ping Ao, Qian Niu +2
We give a general review of recent developments in the theory of vortices in superfluids and superconductors, discussing why the dynamics of vortices is important, and why some key…
Theory of Hall Anomaly in the Mixed State
P. Ao
Analogous to Peierls' arguments for the `anomalous' Hall in metals I demonstrate that the Hall anomaly in the mixed state of superconductors, the sign change of the Hall resistivit…
Vortex Dynamics, Resistivity Formula, and Fluctuation-dissipation Theorems
X. -M. Zhu, P. Ao
We investigate the problem of forces on moving vortex in a superfluid or superconductor. The main purpose is to locate the source which leads to the contradictory results in the li…
