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…
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…
Vortex Dynamics within the BCS Theory
P. Ao, X. -M. Zhu
We outline a conventional path integral derivation of the transverse force and the friction for a vortex in a superconductor based on the BCS theory. The derivation is valid in bot…
Motion of Vacancies in a Pinned Vortex Lattice: Origin of the Hall Anomaly
P. Ao
Physical arguments are presented to show that the Hall anomaly is an effect of the vortex many-body correlation rather than that of an individual vortex. Quantitatively, the charac…
