Nonequilibrium Quantum Phase Transitions in the Ising Model — •Victor Manuel Bastidas Valencia, Clive Emary, Gernot Schaller, and Tobias Brandes — Institut für Theoretische Physik, Technische Universität Berlin, Hardenbergstr. 36, 10623 Berlin, Germany

We establish a set of nonequilibrium quantum phase transitions in the Ising model driven under monochromatic nonadiabatic modulation of the transverse field. We show that besides the Ising-like critical behavior, the system exhibits a novel anisotropic transition which is absent in equilibrium. The novel nonequilibrium quantum phases correspond to states which are synchronized with the external control in the long-time dynamics. A preprint including our results is available under the arXiv Reference: arXiv:1207.5242v1
