Linear and nonlinear optical torque in multi-level atomic systems driven by counter-rotating orbital angular momentum fields
Dharma P. Permana, Mažena Mackoit SinkeviÄienÄ, ViaÄeslav KudriaÅ¡ov +3
We investigate the generation of optical torque in coherently prepared multi-level atomic media driven by a vector vortex beam composed of two counter-rotating components carrying…
Propagation of optical vector vortices of slow light in a coherently prepared tripod configuration
Dharma P. Permana, Mažena Mackoit SinkeviÄienÄ, Julius Ruseckas +1
We investigate the propagation of optical vector vortices of slow light in a coherently prepared four-level tripod atomic system. The vector vortex consists of superposed pulse pai…
Coherent phase control of orbital-angular-momentum light-induced torque in a double-tripod atom-light coupling scheme
Hamid R. Hamedi, ViaÄeslav KudriaÅ¡ov, Mažena Mackoit-SinkeviÄienÄ +1
We investigate a phase-controllable mechanism for generating optical torque in a five-level double-tripod (DT) atom-light coupling scheme interacting with four strong coherent cont…
Spin-orbit coupling of optical vector vortices in coherently prepared media
Dharma P. Permana, Mazena Mackoit SinkeviÄienÄ, Julius Ruseckas +1
We investigate the propagation of an optical vector vortex weakly interacting with a coherently prepared atomic medium (phaseonium) in a three-level configuration. The vector…
Indoor Localization Based on MSC Map
Åukasz KuÅacz, Adrian Kliks, Julius Ruseckas +1
In this short paper, we propose a technique for AI-based identification of modulation and coding schemes (MCS) in surrounding cellular signals. Based on the created MCS map, we eva…
Adiabatons in a double tripod coherent atom-light coupling scheme
ViaÄeslav KudriaÅ¡ov, Hamid R. Hamedi, Julius Ruseckas
Optical adiabatons are specific shape-invariant pulse pairs propagating at the reduced group velocity and without optical absorption in the medium. The purpose of this study is to…
