Protecting quantum coherence of two-level atoms from vacuum fluctuations of electromagnetic field [PDF]
, 2015 In the framework of open quantum systems, we study the dynamics of a static polarizable two-level atom interacting with a bath of fluctuating vacuum electromagnetic field and explore under which conditions the coherence of the open quantum system is ...

Dynamical Features of Isolated Two- and Three-Level Atoms Interacting with a Cavity Field
Advances in Mathematical Physics, 2022 Some dynamical features of two- and three-level atoms interacting locally with an ideal cavity field are investigated. These dynamical features are introduced by employing the statistical atomic inversion, entropy squeezing, and tomographic entropy.

Entanglement dynamics for uniformly accelerated two-level atoms coupled with electromagnetic vacuum fluctuations [PDF]
, 2016 We investigate the entanglement dynamics of two uniformly accelerated atoms with the same acceleration perpendicular to their separation. The two-atom system is treated as an open system coupled with fluctuating electromagnetic fields in the Minkowski ...

On hybrid states of two and three level atoms
, 2005 We calculate atom-photon resonances in the Wigner-Weisskopf model, admitting two photons and choosing a particular coupling function. We also present a rough description of the set of resonances in a model for a three-level atom coupled to the photon ...

Generation of entangled states of two three-level atoms in cavity QED [PDF]
, 2003 We present a scheme to generate maximally entangled states of two three-level atoms with a nonresonant cavity by cavity-assisted collisions. Since the cavity field is only virtually excited no quantum information will be transferred from the atoms to the

Double dressing by both the number of atoms and the number of photons inside cavity
Results in Physics, 2023 We study a system of N two-level atoms interacting with a coherent field a resonant cavity in a self-consistent manner. No direct correlation between the atoms, such as induced by dipole–dipole interaction, is included. Initially all atoms are not exited,

Two-Level Atom at Finite Temperature
Acta Physica Polonica A, 2009 Properties of a two-level atom coupled to the quantized electromagnetic field at finite temperature are determined. The analysis is based on a new method (inspired by QED) of describing qubits, developed previously at zero temperature (Phys. Rev. A 76, 062106 (2007)).
