Free Energy,Stability, and Particle Source in Dynamical Holography

We study dynamical holographic systems and the relation between thermodynamical and dynamical stability of such systems, using the conserved currents in the bulk spacetime. In particular, in the probe limit a generalized free energy is defined with the property of monotonic decreasing in dynamic processes. It is then shown that the(absolute) thermodynamical stability implies the dynamical stability, while the linear dynamical stability implies the thermodynamical(meta-)stability. The holographic...
