Dissipative Dynamics in Open Fermionic Chains
A. I. Karanikas, G. E. Pavlou
By merging the Feynman-Vernon's approach with the out-of-equilibrium Keldysh-Schwinger formalism, we construct the reduced generating functional through which all the time-dependen…
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…
Microscopic Study of Superfluidity in Dilute Neutron Matter
G. E. Pavlou, E. Mavrommatis, Ch. Moustakidis +1
Singlet -wave superfluidity of dilute neutron matter is studied within the correlated BCS method, which takes into account both pairing and short-range correlations. First, the…
