Azimuthal modulation of electromagnetically-induced transparency by using asymmetrical Laguerre-Gaussian beams
Seyedeh Hamideh Kazemi, Mohammad Mahmoudi
Recently, the generation and detection of structured light field have drawn a great deal of attention, due to their importance in high-capacity optical data storage and quantum tec…
Phase-dependent light-induced torque
Seyedeh Hamideh Kazemi, Mohammad Mahmoudi
Optical torque on individual atoms in a Bose-Einstein condensate can rotate the ensemble and generate a current flow [Phys. Rev. A 82, 051402 (2010)]. We exploit the fact to sugges…
Phase-controlled photon drag in a slow-light moving medium
Seyedeh Hamideh Kazemi, Mohammad Mahmoudi
In recent years, photon drag has attracted enormous attention owing to both fundamental and practical interests. In this paper, by presenting a density-matrix approach, we have the…
Controllable optical bistability in a cavity optomechanical system with a Bose-Einstein condensate
Seyedeh Hamideh Kazemi, Saeed Ghanbari, Mohammad Mahmoudi
The optical bistability (OB) in a two-mode optomechanical system with a Bose-Einstein condensate (BEC) is studied. By investigating the behavior of steady state solutions, we show…
Localizing an atom using Laguerre-Gaussian beams
Seyedeh Hamideh Kazemi, Mohadeseh Veisi, Mohammad Mahmoudi
Use of the Laguerre-Gaussian fields in an atom-light interaction makes the linewidth of the optical spectrum narrow. We exploit this fact for providing the ability to accomplish si…
Super-ultralow temperature laser cooling via interacting dark-state resonances
Vase Moeini, Seyedeh Hamideh Kazemi, Mohammad Mahmoudi
We propose a laser cooling mechanism that leads to a temperature significantly lower than the single-photon recoil limit, about . This mechanism benefits fr…
