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…
Coherent-state path integrals in the continuum: The SU(2) case
G. Kordas, D. Kalantzis, A. I. Karanikas
We define the time-continuous spin coherent-state path integral in a way that is free from inconsistencies. The proposed definition is used to reproduce known exact results. Such a…
Non-equilibrium dynamics in dissipative Bose-Hubbard chains
G. Kordas, D. Witthaut, S. Wimberger
Open many-body quantum systems have recently gained renewed interest in the context of quantum information science and quantum transport with biological clusters and ultracold atom…
The Dissipative Bose-Hubbard Model. Methods and Examples
G. Kordas, D. Witthaut, P. Buonsante +4
Open many-body quantum systems have attracted renewed interest in the context of quantum information science and quantum transport with biological clusters and ultracold atomic gas…
Coherent state path integrals in the continuum
G. Kordas, S. I. Mistakidis, A. I. Karanikas
We discuss the time-continuous path integration in the coherent states basis in a way that is free from inconsistencies. Employing this notion we reproduce known and exact results…
Entropy production in Gaussian bosonic transformations using the replica method: application to quantum optics
C. N. Gagatsos, A. I. Karanikas, G. Kordas +1
In spite of their simple description in terms of rotations or symplectic transformations in phase space, quadratic Hamiltonians such as those modeling the most common Gaussian oper…
