Holographic Response of Electron Clouds
arXiv:1810.11416 · doi:10.1007/JHEP03(2019)019
Abstract
In order to make progress towards more realistic models of holographic fermion physics, we use gauge/gravity duality to compute the dispersion relations for quasinormal modes and collective modes for the electron cloud background, i.e. the non-zero temperature version of the electron star. The results are compared to the corresponding results for the Schwarzschild and Reissner-Nordström black hole backgrounds, and the qualitative differences are highlighted and discussed.
