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…
Double Counting of `Chiral Anomaly' in a Model Study of Primordial Baryogenesis
P. Ao
In this comment to the Nature paper of Bevan et al I point out that their interpretation of experimental data is based on a double counting of the `chiral anomaly' due to a vortex…
