Quantum States of a Two-Level Atom trapped in a Helical Optical Tube
V. E. Lembessis, A. Lyras, O. M. Aldossary
We investigate the quantized states of a two-level Rb atom which is trapped by the optical dipole potential when the atom interacts with a helical optical tube (HOT) light field. T…
A Novel Metal Nanoparticles- Graphene Nanodisks- Quantum Dots Hybrid-System-Based Spaser
Mariam Tohari, Andreas Lyras, Mohamad AlSalhi
Active nanoplasmonics has recently led to the emergence of many promising applications. One of them is spaser (surface plasmons amplification by stimulated emission of radiation) t…
Ultrafast Energy Transfer in the Metal Nanoparticles-Graphene Nanodisks-Quantum Dots Hybrid Systems
Mariam Tohari, Andreas Lyras, Mohamad AlSalhi
Hybrid nanocomposites can offer a wide range of opportunities to control the light-matter interac- tion and electromagnetic energy flow at the nanoscale, leading to exotic optoelec…
Rotating Optical Tubes: An Archimedes' Screw for Atoms
Anwar Al Rsheed, Andreas Lyras, Omar M. Aldossary +1
The classical dynamics of a cold atom trapped inside a vertical rotating helical optical tube (HOT) is investigated by taking also into account the gravitational field. The resulti…
Quantum Hall Physics with Cold Atoms in Cylindrical Optical Lattices
Mateusz Łącki, Hannes Pichler, Antoine Sterdyniak +5
We propose and study various realizations of a Hofstadter-Hubbard model on a cylinder geometry with fermionic cold atoms in optical lattices. The cylindrical optical lattice is cre…
Radiation pattern of two identical emitters driven by a Laguerre-Gaussian beam: An atom nanoantenna
Vassilis E. Lembessis, Andreas Lyras, Anwar Al Rsheed +2
We study the directional properties of a radiation field emitted by a geometrically small system composed of two identical two-level emitters located at short distances and driven…
