Generating non-classical correlations in two-level atoms
Alexandria Engineering Journal, 2023 We address the effective generation of thermal non-classical correlations in two two-level atoms when exposed to a Fock-state cavity incorporated with classical decoherence effects.

Controllable single-photon routing between two waveguides by two giant two-level atoms
Frontiers in Physics, 2022 We investigate the single-photon quantum routing composed of two infinite waveguides coupled to two giant two-level atoms. The exact expressions of the single-photon transmission and reflection amplitudes are derived with the real-space approach.

Retrodiction with two-level atoms: atomic previvals [PDF]
Journal of Modern Optics, 2002 In the Jaynes-Cummings model a two-level atom interacts with a single-mode electromagnetic field. Quantum mechanics predicts collapses and revivals in the probability that a measurement will show the atom to be excited at various times after the initial preparation of the atom and field.

An efficient quantum memory based on two-level atoms
New Journal of Physics, 2013 We propose a method to implement a quantum memory for light based on ensembles of two-level atoms. Our protocol is based on controlled reversible inhomogeneous broadening (CRIB), where an external field first dephases the atomic polarization and thereby ...

Cavity-Induced Optical Nonreciprocity Based on Degenerate Two-Level Atoms [PDF]
NanomaterialsWe developed and experimentally realized a scheme of optical nonreciprocity (ONR) by using degenerate two-level atoms embedded in an optical ring cavity.

Quadrupole interaction of non-diffracting beams with two-level atoms
Results in Physics, 2019 Recently it has been shown that the quadrupole interactions can be improved significantly as the atom interacts at near resonance with the Laguerre-Gaussian (LG) mode.

Theoretical treatment of the interaction between two-level atoms and periodic waveguides. [PDF]
Optics Letters, 2015 Light transport in periodic waveguides coupled to two-level atoms is investigated theoretically. By using optical Bloch equations and a photonic modal formalism, we derive a convenient semi-analytical expression for calculating the scattering matrix of ...

Electro-optic quantum memory for light using two-level atoms. [PDF]
Physical Review Letters, 2006 We present a simple quantum memory scheme that allows for the storage of a light field in an ensemble of two-level atoms. The technique is analogous to the NMR gradient echo for which the imprinting and recalling of the input field are performed by ...

Dynamics and quantum entanglement of two-level atoms in de Sitter spacetime [PDF]
, 2014 In the framework of open quantum systems, we study the internal dynamics of both freely falling and static two-level atoms interacting with quantized conformally coupled massless scalar field in de Sitter spacetime.
