Noise-induced quantum phase transitions in optical lattices — •Maria Eckholt, Juan Jose Garcia-Ripoll, and Ignacio Cirac — Max-Planck-Institut für Quantenoptik, Hans-Kopfermann Str. 1, 85748 Garching, Germany

We study the quantum phase transitions in ultracold atoms subjected to a noisy environment. The system is modeled by the Bose-Hubbard Hamiltonian, where periodic boundary conditions are considered. The study is based on the master-equation formalism and we apply different numerical techniques to estimate the phases of the atoms. Experimental realizations for different types of noise are also considered.
