Holographic Thermalization in Charged Dilaton Anti-de Sitter Spacetime
We study holographic thermalization in spacetimes with a chemical potential
and a non-trivial dilaton field. Three non-local observables are used to probe
the whole process and investigate the effect of the ratio of the chemical
potential over temperature and the dilaton-Maxwell coupling constant
. It is found that the saturation time is not always a monotonically
increasing function of , the situation depends on . When , larger yields longer saturation time, while for
, the situation becomes more complex. More interesting, we found that
although indeed has influence on the whole thermalization process, it
nearly does not affect the saturation time, which indicates the universality of
the saturation time for the dual one-parameter field theories.Comment: 22 pages, 5 figure
