  We consider a Langevin-like model which describes a one-dimensional massive
particle in a harmonic potential and subjected to two heat baths and one
athermal environment. The thermal noises are white and Gaussian, and the
temperatures of heat reservoirs are distinct. The athermal medium act through
an external non-Gaussian noise of Poisson type. We study the stationary
properties of average heat and energy injected by external stochastic force. We
also determine the long-time behavior of the covariances of time-integrated
power due to external noise and heat exchanged with thermal environments.
