Mean-field dynamics of a Bose-Hubbard chain coupled to a non-Markovian environment
G. Kordas, G. E. Pavlou, A. I. Karanikas
We study the dynamics of an interacting Bose-Hubbard chain coupled to a non-Markovian environment. Our basic tool is the reduced generating functional expressed as a path integral…

Life-times of quantum resonances through the Geometrical Phase Propagator Approach
G. E. Pavlou, A. I. Karanikas, F. K. Diakonos
We employ the recently introduced Geometric Phase Propagator Approach (GPPA) [Phys. Rev. A85, 062110 (2012)] to develop an improved perturbative scheme for the calculation of life…
