Description
We describe a quantum fluid undergoing constant acceleration in the grand canonical ensemble, in thermal equilibrium at finite inverse temperature β. Writing the action of the density operator ρ as a Poincare transformation with imaginary parameters, we derive the Kubo-Martin-Schwinger (KMS) relation characterizing the two-point functions. The KMS relation sets boundary conditions for the Euclidean propagator, identifying points in the τ-z plane on a circle separated by an angle equal to the thermal acceleration α. When α/2π = p/q is a rational number, we find a fractalization of thermodynamics, similar to the case of states under imaginary rotation.
