  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.
