We use holographic techniques to study the zero-temperature limit of dissipation for a Brownian particle moving in a strongly coupled CFT at finite temperature in various space-time dimensions. The dissipative term in the boundary theory for ω→ 0, T → 0 with ω/ T held small and fixed, does not match the same at T=0, ω→ 0. Thus the T→ 0 limit is not smooth for ω< T. This phenomenon appears to be related to a confinement-deconfinement phase transition at T=0 in the field theory.
