On the Role of Latent Variables in Stochastic Thermodynamics — •Jannik Ehrich and Andreas Engel — Institut für Physik, Carl von Ossietzky Universität, 26111 Oldenburg, Germany

Hidden variables play an important role for the entropy balance in stochastic thermodynamics. By constructing a general bipartite Markov chain we elaborate on several limiting cases including the setup of a sensor, a measurement-feedback-loop and a hidden Markov model. We derive and explain fluctuation theorems relevant to each of these setups. This view promises a unified approach for the understanding of the role of latent variables in stochastic thermodynamics.
