Dynamics of the Ising chain coupled to a Markovian bath — •Birger Horstmann, Tommaso Roscilde, Michael Wolf, and Ignacio Cirac — Max-Planck-Institut für Quantenoptik, Garching

In this talk we discuss the dynamics of an Ising chain coupled to a Markovian bath. We simulate the dynamics of the system with a Lindblad master equation and study the decoherence of the ground state of the Ising chain in time focussing on the effect of the quantum phase transition of the Ising chain on the decoherence rates. We propose to simulate such a system in an optical lattice.
