Vortices and impurities

Vortices and impurities

We describe the BPS dynamics of vortices in the presence of impurities. We argue that a moduli space of solitons survives the addition of both electric and magnetic impurities. However, dynamics on the moduli space is altered. In the case of electric impurities, the metric remains unchanged but the dynamics is accompanied by a connection term, acting as an effective magnetic field over the modu...

Physical Simulation of Baroclinic Waves and Vortices in the Atmosphere

Vortices ∗

I discuss in these lectures vortex-like classical solutions to the equations of motion of gauge theories with spontaneous symmetry breaking. Starting from the Nielsen-Olesen ansatz for the Abelian Higgs model, extensions to the case in which gauge dynamics is governed by Yang-Mills and Chern-Simons actions are presented. The case of semilocal vortices and also the coupling to axions is analyzed...

Water and Its Impurities

most versatile and sensitive tools for micro-chemical studies of biological material. Since the publication of Volume I, which covers this topic very briefly, many advances have been made both in the development of new procedures and in the adaptation of existing ones to the micro-chemical level. Although the latter deficit is recognized by Dr. Glick in the preface to Volume II, it is unfortuna...
