The Kohn-Luttinger Effect in Gauge Theories
Kohn and Luttinger showed that a many body system of fermions interacting via short range forces becomes superfluid even if the interaction is repulsive in all partial waves. In gauge theories such as QCD the interaction between fermions is long range and the assumptions of Kohn and Luttinger are not satisfied. We show that in a U(1) gauge theory the Kohn-Luttinger phenomenon does not take plac...
متن کاملKohn-Luttinger effect and the instability of a two-dimensional repulsive Fermi liquid at T=0.
We consider the possibility for a pairing in a two-dimensional (2D) repulsive Fermi liquid due to the singularity in the scattering amplitude I (q) at the momentum transfer q 2pF (Kohn-Luttinger efFect). A common belief based on perturbative calculations up to second order in the s-wave scattering amplitude is that this effect is absent in two dimensions. I show that this is not the case. For a...
متن کاملCharges in Gauge Theories
Recent progress in the construction of both electric, coloured and magnetic charges in gauge theories will be presented. The topological properties of the charged sectors will be highlighted as well as the applications of this work to confinement and infrared dynamics.
متن کاملGauge dependence in topological gauge theories
We parametrize the gauge-fixing freedom in choosing the Lagrangian of a topological gauge theory. We compute the gauge-fixing dependence of correlators of equivariant operators when the compactified moduli space has a non-empty boundary and verify that only a subset of these has a gauge independent meaning. We analyze in detail a simple example of such anomalous topological theories, 4D topolog...
متن کاملTopological interactions in gauge theories
Much of the relevant physics described by gauge theories is non-perturbative in nature; for example features like the spectrum, the confinement phenomenon and the study of topological defects and their physical properties. The research in the my group has in recent years focused on some up to now poorly understood non perturbative features of topological defects in gauge theories such as their ...
