A full quantum mechanical treatment of open quantum systems via a Master equation is
often limited by the size of the underlying Hilbert space. As an alternative, the dynamics can …

Results from higher order mean-field calculations of light interacting with atom arrays are
presented for calculations of one-and two-time expectation values. The atoms are …

We theoretically and computationally investigate the behavior of infinite atom arrays when
illuminated by nearly resonant light. We use higher-order mean-field equations to …

We present a theoretical description for a lasing scheme for atoms with three internal levels
in a V configuration and interacting with an optical cavity. The use of a V-level system allows …

We investigate properties of the lasing action observed on the 1S0--3P1 intercombination
transition of ytterbium atoms that are laser-cooled and-trapped inside a high-finesse cavity …

(English) Photons have emerged as the main candidates for carrying quantum information
due to their weak interaction with the environment. Unfortunately, their limited interaction …

In superradiant lasers the emitted light has a frequency determined mainly by atoms, as
opposed to ordinary lasers, where mechanical parts have a large influence. And while …

Numerical simulation of the full quantum dynamics of open quantum systems is often limited
by the sheer size of the underlying Hilbert space. Commonly, numerical approaches use …
