Holographic Response of Electron Clouds

Understand

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-Nordstr\"om black hole backgrounds, and the qualitative differences are highlighted and discussed.
