Detectors interacting through quantum fields: Non-Markovian effects, non-perturbative generation of correlations and apparent non-causality
Theodora Kolioni, Charis Anastopoulos
We study the system of two localized detectors (oscillators) interacting through a massless quantum field in a vacuum state via an Unruh-DeWitt coupling. This system admits an exac…
Faithful extraction of quantum coherence
Nikolaos K. Kollas, Kostas Blekos
Coherence, a strictly quantum phenomenon, has found many applications, from quantum information theory and thermodynamics to quantum foundations and biology. When physical constrai…
Coherent population oscillations and an effective spin-exchange interaction in a symmetric polariton mixture
P. A. Kalozoumis, G. M. Nikolopoulos, D. Petrosyan
We study a two-species mixture of exciton-polaritons with self- and cross-interaction nonlinearities in a double well structure, in the presence of relaxation and continuous pumpin…
Speeding up adiabatic passage with an optimal modified Roland-Cerf protocol
Dionisis Stefanatos, Emmanuel Paspalakis
In this article we propose a novel method to accelerate adiabatic passage in a two-level system with only longitudinal field (detuning) control, while the transverse field is kept…
Resonant shortcuts for adiabatic rapid passage with only -field control
Dionisis Stefanatos, Emmanuel Paspalakis
In this work we derive novel ultrafast shortcuts for adiabatic rapid passage for a qubit where the only control variable is the longitudinal -field, while the transverse -fie…
Complete energy conversion between light beams carrying orbital angular momentum using coherent population trapping for a coherently driven double-Λatom-light coupling
Hamid Reza Hamedi, Emmanuel Paspalakis, Giedrius Žlabys +2
We propose a procedure to achieve a complete energy conversion between laser pulses carrying orbital angular momentum (OAM) in a cloud of cold atoms characterized by a double-Λatom…
