Steady-state properties of a one dimensional spin chain under dissipation — •Heike Schwager, Ignacio Cirac, and Geza Giedke — Max-Planck-Institut für Quantenoptik, 85748 Garching

We study the steady state properties of local one dimensional spin Hamiltonians under different types of dissipation. We find that under certain conditions the steady state depends discontinuously on system parameters in the limit of weak dissipation and give an explanation for the appearance of this phase transition. Moreover, we discuss state preparation with this spin chain under dissipation and discuss physical implementations of this system.
