Some aspects of vortex dynamics theories are critically examined. The discussion is placed in the context of experiments on the Josephson-Anderson effect and on the Hall anomaly in the mixed state.

Snapshots on Vortex Dynamics

Salient features of vortex dynamics in super media are summarized. Recent examples are: the demonstration of prominent role of topology in vortex dynamics; the solution to the Hall anomaly which once

Two years later--lessons from vortex dynamics in super media

Two years ago the reasons for resistance to the fundamental vortex dynamics in super media emerged in 1990's were analyzed (cond-mat/0407007). Five "mistakes" were identified to explain this



Microscopic theory of vortex dynamics in homogeneous superconductors

Vortex dynamics in fermionic superfluids is carefully considered from the microscopic point of view. Finite temperatures, as well as impurities, are explicitly incorporated. To enable readers

A scenario to the anomalous Hall effect in the mixed state of superconductors

We argue that the motion of vacancies in a pinned vortex lattice may dominate the contribution to the Hall effect in an appropriate parameter regime for a superconductor. Based on this consideration

It is shown that the en route vortex velocity dependent part of the Magnus force in a Josephson junction array is effectively zero, and the Hall effect in the classical limit is predicted, and rich and complex Hall behaviors analogous to the Thouless-Kohmoto-Nightingale-den Nijs effect are found in the quantum regime.

Berry's phase and the Magnus force for a vortex line in a superconductor.

It is found that there is no influence of the disorder and the electromagnetic field on the existence of the Magnus force in the superconducting state, and its magnitude is proportional to the superfluid electron density.

Nernst effect, seebeck effect, and vortex dynamics in the mixed state of superconductors

We demonstrate that in the presence of pinning a simple relation exists between Nernst and Seebeck coefficients and the resistivity tensor, based on the vortex equation of motion and the two-fluid

Observation of the Transverse Force on Moving Vortices in YBCO Films

We have designed a mechanical experiment to measure the total transverse force on moving vortices in a type II superconductor. The vortices are driven into motion by the vibration of a magnet above a

Origin of Hall Anomaly in the Mixed State

There has been a corporative absence of understanding of Hall anomaly data in the mixed state in terms of vortex many-body effect and pinning, because of the dominant theoretical influence. Now

Transverse force on a quantized vortex in a superfluid.

An exact expression for the total nondissipative transverse force acting on a quantized vortex moving in a uniform background is derived and it is concluded that contributions of the localized core states do not change this force.

Motion of vacancies in a pinned vortex lattice: origin of the Hall anomaly

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 characteristic energy
