Strongly confined atomic localization by Rydberg coherent population trapping
Teodora Kirova, Ning Jia, Seyyed Hossein Asadpour +3
In this letter we investigate the possibility to attain strongly confined atomic localization using interacting Rydberg atoms in a Coherent Population Trapping (CPT) ladder configu…
Ultraprecise Rydberg atomic localization using optical vortices
Ning Jia, Teodora Kirova, Gediminas Juzeliunas +2
We propose a robust localization of the highly-excited Rydberg atoms, interacting with doughnut-shaped optical vortices. Compared with the earlier standing-wave (SW)-based localiza…
Control of nonlinear optical phenomena and spatially structured optical effects in a four-level quantum system near a plasmonic nanostructure
Hamid Reza Hamedi, Vassilios Yannopapas, Emmanuel Paspalakis
We investigate the nonlinear optical response of a four-level double-V-type quantum system interacting with a pair of weak probe fields while located near a two-dimensional array o…
Manipulation and exchange of Light with Orbital Angular Momentum in Quantum Dot Molecules
Mahboubeh Mahdavi, Zahra Amini Sabegh, Mohammad Mohammadi +2
We study the interaction of laser pulses carrying orbital angular momentum (OAM) with structural asymmetry quantum dot molecules characterized by four energy levels. We demonstrate…
Off-axis optical vortices using double-Raman singlet and doublet light-matter schemes
Hamid Reza Hamedi, Julius Ruseckas, Emmanuel Paspalakis +1
We study the formation of off-axis optical vortices propagating inside a double-Raman gain atomic medium. The atoms interact with two weak probe fields as well as two strong pump b…
