One-atom laser based on electromagnetically-induced transparency, suggested recently [Phys. Rev. Lett. 124, 093603 (2020)], is capable of generating Schrödinger cat states in the regime of strong ground-state coupling. In this regime, we find the exact solution for the Schrödinger equation with a time-dependent effective Hamiltonian by considering the Magnus expansion of the time-ordered exponential and calculating analytically the time-ordering terms, omitted in the previous study. We show… Expand

Single-atom laser: Coherent and nonclassical effects in the regime of a strong atom-field correlation
Based on the approximation of strong correlations between an atom and an intracavity field, which implies the equal probabilities of finding the atom in the ground state and n photons in the fieldExpand
Experimental realization of a one-atom laser in the regime of strong coupling
Observations of the second-order intensity correlation function demonstrate that the experimental realization of a one-atom laser operated in the regime of strong coupling generates manifestly quantum (nonclassical) light, typified by photon anti-bunching and sub-poissonian photon statistics.

Time-ordering effects in the generation of entangled photons using nonlinear optical processes.
An intuitive picture is constructed that allows us to predict when time-ordering effects significantly modify the joint spectral amplitude (JSA) of the photons generated in SPDC and SFWM. Expand
Electromagnetically induced transparency with single atoms in a cavity
This work demonstrates EIT with a single atom quasi-permanently trapped inside a high-finesse optical cavity, where the atom acts as a quantum-optical transistor with the ability to coherently control the transmission of light through the cavity. Expand
Generation of mesoscopic quantum superpositions through Kerr-stimulated degenerate downconversion
A two-step interaction scheme involving (2) and (3) nonlinear media is suggested for the generation of Schrodinger cat-like states of a single-mode optical field. In the first step, a weak coherentExpand

Preparation of stationary Fock states in a one-atom Raman laser.
The possibility of preparing low-photon-number eigenstates of a single damped cavity mode coupled to a single three-level atom in a Raman lambda configuration is demonstrated and both the atom-field coupling strength and cavity loss rate lie within 1 order of magnitude of what is achievable in current experimental setups.
