Feedback control of interacting transport channels — •Tobias Brandes — Institut für Theoretische Physik, TU Berlin

Understanding the flow of information is crucial for interpreting feedback control of stochastic processes. Quantitative tools are available in the form of modified fluctuation relations, mutual information and flows in the framework of stochastic thermodynamics for discrete or continuous degrees of freedom [1].

In this talk, I present an extension of a previous non-autonomous feedback model for transport of particles that was based on the synchronization with an external clock [2]. The new autonomous model can be viewed as a paradigm for interacting feedback mechanisms or feedback in networks [3], where the control is achieved in a collective manner.
