Approximation scheme and non-Hermitian renormalization for the description of atom-field-system evolution

B Ahmadi, RR Rodríguez, R Alicki, M Horodecki - Physical Review A, 2024 - APS
Interactions between a source of light and atoms are ubiquitous in nature. The study of them
is interesting on the fundamental level as well as for applications. They are at the core of …

Relating binding energy and scattering length of weakly bound dimers of strontium

LD Augustovičová, V Špirko - Annalen der Physik, 2021 - Wiley Online Library
The s‐wave scattering length (a) is an important parameter in ultracold collisions and
precision tests of fundamental physics, yet its accurate calculation remains a challenge …

Full optical preparation of an absolute ground-state ultracold CsYb molecule via laser-assisted self-induced Feshbach resonance

ZX Sun, BK Lyu, GR Wang… - Journal of Physics B …, 2022 - iopscience.iop.org
We investigate theoretically the formation of an ultracold CsYb molecule in the absolute
ground state by full optical control. The laser-assisted self-induced Feshbach resonance …
