Optimal shortcuts of Stimulated Raman Adiabatic Passage in the presence of dissipation
Dionisis Stefanatos, Emmanuel Paspalakis
We use optimal control theory to obtain shortcuts to adiabaticity which maximize population transfer in a three-level STIRAP system, for a given finite duration of the process and…
On the optimality of optical pumping for a closed -system with large decay rates of the intermediate excited state
Dionisis Stefanatos, Emmanuel Paspalakis
We use optimal control theory to show that for a closed -system where the excited intermediate level decays to the lower levels with a common large rate, the optimal scheme for…
Relativistic time-of-arrival measurements: predictions, post-selection and causality problem
Charis Anastopoulos, Maria-Electra Plakitsi
We analyze time-of-arrival probability distributions for relativistic particles in the context of quantum field theory (QFT). We show that QFT leads to a unique prediction, modulo…
Quantum Stirling heat engine with squeezed thermal reservoir
Nikolaos Papadatos
We analyze the performance of a quantum Stirling heat engine (QSHE), using a two level system and the harmonic oscillator as the working medium, that contacts with a squeezed therm…
Quantum Field Theory based Quantum Information: Measurements and Correlations
Charis Anastopoulos, Bei-Lok Hu, Konstantina Savvidou
This is the first in a series of papers aiming to develop a relativistic quantum information theory in terms of unequal-time correlation functions in quantum field theory. In this…
Cohering and decohering power of massive scalar fields under instantaneous interactions
N. K. Kollas, D. Moustos, M. R. Muñoz
Employing a non-perturbative approach based on an instantaneous interaction between a two-level Unruh-DeWitt detector and a massive scalar field, we investigate the ability of the…
