| Popis: | It is often said that interactions destroy the particle nature of excitations. We report that, in holographic theory adding interaction term can create a new quasi particle spectrum, on the contrary. We show this by calculating the optical conductivity in a model with exact background solution and finding a new quasi-particle spectrum. Such new poles are consequence of some non-minimal interaction like Chern-Simon term. We also point out that the origin of the new peak in our example is the vortex formation by the anomalous magnetic moment induced by the interaction term. |
