Universal property of single topological singularity dynamics
P. Ao, X. -M. Zhu
Using the random matrix theory we demonstrate explicitly the insensitivity of the transverse force on a moving vortex to non-intrinsic and non-magnetic impurities in a superconduct…
Quantum Spinodal Decomposition in Multicomponent Bose-Einstein Condensates
S. T. Chui, P. Ao
We investigate analytically the non-equilibrium spatial phase segregation process of a mixture of alkali Bose-Einstein condensates. Two stages (I and II) are found in analogy to th…
Role of Impurities in Core Contribution to Vortex Friction
P. Ao, X. -M. Zhu
We present a microscopic calculation of core states contribution to vortex friction in a type II superconductor at zero temperature. In weak impurity limit, a perturbative calculat…
Friction Coefficient and Berry Phase for a Topological Singularity in a Superfluid
X. -M. Zhu, P. Ao
The coexistence of the universal transverse force and the non-universal friction force on a topological singularity in a superfluid is shown here. Based on the BCS type microscopic…
Aharonov-Bohm and Aharonov-Casher Effects: Connections to Dynamics of Topological Singularities
P. Ao, Q. Niu
We analyze the physical processes involved in the Aharonov-Bohm (A-B) and the Aharonov-Casher (A-C) effects, showing that an incomplete A-B effect knowledge can lead a totally wron…
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…
