Dynamics after connecting two fermionic chains — •Jacopo Viti1, Jean-Marie Stephan1, Jerome Dubail2, and Masud Haque11Max Planck Institute for the Physics of Complex Systems, Nöthnitzer Straße 38, 01187 Dresden — 2Universite de Lorraine, 34 Cours Léopold, 54000 Nancy, France

I will consider a simple out-of-equilibrium protocol: Two one-dimensional systems of free fermions are initially prepared at different densities and/or temperatures; they are then joined together and allowed to evolve unitarily. I will describe the time evolution of two-point correlation functions, discussing in particular their stationary value and the way the steady regime is attained. Particle and thermal currents will be also analyzed. A description in terms of the semi-classical Wigner function will be presented.
