真空中Aharonov-Bohm相互作用的平凡性

Triviality of the Aharonov-Bohm interaction in a spatially confining vacuum

Dmitri Antonov

摘要:

本文探讨了双朗道-金兹伯格理论(DLGT)真空的磁荷激发与同一真空中存在的双Abrikosov涡旋之间的长程相互作用。我们证明了在DLGT的伦敦极限下,相应的Aharonov-Bohm型相互作用具有这样的耦合,使得相互作用降低到e^{2πi(整数)}的一个平凡因子.在SU(N_c)启发的[U(1)]^{N_c-1}-不变DLGT以及由Chern-Simons项扩展的DLGT中进行了相同的分析。它进一步明确表明,陈-西蒙斯项导致的外观打结的双重Abrikosov涡。

英文摘要:

This paper explores long-range interactions between magnetically-charged excitations of the vacuum of the dual Landau-Ginzburg theory (DLGT) and the dual Abrikosov vortices present in the same vacuum. We show that, in the London limit of DLGT, the corresponding Aharonov-Bohm-type interactions possess such a coupling that the interactions reduce to a trivial factor of e^{2πi (integer)}. The same analysis is done in the SU(N_c)-inspired [U(1)]^{N_c-1}-invariant DLGT, as well as in DLGT extended by a Chern-Simons term. It is furthermore explicitly shown that the Chern-Simons term leads to the appearance of knotted dual Abrikosov vortices.
