A revision of the forces exerted in the Rayleigh regime by a tighlty focused optical vortex tweezer
Khalid Aloufi, Vasileios E. Lembessis, Omar M. Aldossary
Optical tweezers use light from a tightly focused laser beam to manipulate the motion of tiny particles. When the laser light is strongly focused, but still paraxial, its e/m field…
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…
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…
Rotating artificial gauge magnetic and electric fields
V. E. Lembessis, A. Alqarni, S. Alshamari +2
We consider the creation of artificial gauge magnetic and electric fields created when a two-level atom interacts with an optical Ferris wheel light field.These fields have the spa…
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…
Investigation of the role of the Roentgen interaction in angular momentum transfer within an electric Bose Einstein Condensate
L. G. Bousiakou, O. M. Aldossary, W. S. Almarhoon
The exact action of the Roentgen effect at an atomic level is investigated within the context of vortex formation using two Laguerre Gaussian beams. Starting from a modified Gross-…
