Abstract
We review the mathematics of exactly solvable Unruh-DeWitt detector models, interacting with massive scalar fields under instantaneous interactions, to construct a relativistic quantum Otto heat engine. By deriving the conditions under which the thermodynamic cycle is closed we present preliminary results on the dependence of the extracted work as a function of the relativistic velocities of the detector during its interaction with the hot and cold baths and compare these results for two different couplings defined in the laboratory and the detector’s frame of reference respectively.
