Light-matter interactions in cold dysprosium atoms — •Marcel Trümper1, Niels Petersen1,2, and Patrick Windpassinger1,2 — 1QUANTUM, Institut für Physik, Johannes Gutenberg-Universität Mainz, Staudingerweg 7, 55128 Mainz, Germany — 2Graduate School Materials Science in Mainz, Staudingerweg 9, 55128 Mainz, Germany
The fundamental understanding of light-matter interactions and associated phenomena is one of the central endeavors in quantum optics. Extensive research has been performed on a plethora of different systems, including cold and ultra-cold atomic ensembles covering nearly all elements from the periodic table. We are interested in the experimental study of light-matter interactions in dense dipolar media from atoms with large magnetic moments. Dysprosium is the perfect choice for these experiments, since it is the most magnetic element with a magnetic dipole moment of 10 Bohr-magneton.
With this poster we report on recent activities and future work in our laboratory. First, we present results from spectroscopic studies of the 1001 nm ground state transition in dysprosium [arXiv:1907.05754], where we determined the lifetime and polarization of the excited state and measured the isotope shifts of three bosonic isotopes. Further, we give a perspective on our work towards studies of light-propagation effects in dense samples from cold dysprosium atoms. To this end, we report on a microscopic optical dipole trap, which will enable us to achieve the desired densities for our experiments.
