TY - JOUR T1 - Multicritical behavior in dissipative Ising models JF - Physical Review A Y1 - 2017 A1 - Vincent R. Overbeck A1 - Mohammad F. Maghrebi A1 - Alexey V. Gorshkov A1 - Hendrik Weimer AB -

We analyze theoretically the many-body dynamics of a dissipative Ising model in a transverse field using a variational approach. We find that the steady state phase diagram is substantially modified compared to its equilibrium counterpart, including the appearance of a multicritical point belonging to a different universality class. Building on our variational analysis, we establish a field-theoretical treatment corresponding to a dissipative variant of a Ginzburg-Landau theory, which allows us to compute the upper critical dimension of the system. Finally, we present a possible experimental realization of the dissipative Ising model using ultracold Rydberg gases.
