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…
Coherent-state path integrals in the continuum via geometric de-quantization
P. Lykourgias, I. Lyris, A. I. Karanikas
We present a new method for the consistent construction of time-continuous coherent-state path integrals using the theory of half-form quantization. Through the inversion of the qu…
Fermionic path integrals and correlation dynamics in a 1D XY system
I. Lyris, P. Lykourgias, A. I. Karanikas
We derive time dependent correlation functions in an one dimensional XY spin model with the use of generating functionals, the latter being defined as path integrals over fermionic…
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…
Time-dependent transport through a T-coupled quantum dot
G. E. Pavlou, N. E. Palaiodimopoulos, P. A. Kalozoumis +3
We are considering the time-dependent transport through a discrete system, consiting of a quantum dot T-coupled to an infinite tight-binding chain. The periodic driving that is ind…
