@article{Horoshko2021TimeorderingEI, title={Time-ordering effects in a one-atom laser based on electromagnetically induced transparency}, author={Dmitri B. Horoshko and Chang-shui Yu and Sergei Ya. Kilin}, journal={Journal of the Optical Society of America B}, year={2021} }

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
