The coupling of Bose-condensed atoms with an optical cavity can provide an effective infinite range interaction leading to rich many-body dynamics. As examples, I will discuss sub-recoil cavity cooling, a dynamical phase transition into a self-organized density wave phase related to the open Dicke model, formation of a self-organized Mott-insulator, dynamical melting of a cavity-induced density wave phase and its connection to light-induced superconductivity in cuprates, and timecrystal dynamics.
Prof. Andreas Hemmerich received his Diploma (BSc+MSc-equivalent) in 1985 from the Max-Planck Institute of Physics and Astrophysics & the Ludwig-Maximilians University (LMU) in Munich. He obtained his PhD in 1990 in the group of Prof. Theodor W. Hänsch (Nobel Prize winner in 2005), where he stayed as a research associate until 1995, when he became Assistant Professor at LMU. Since 1996 he is a Professor of Experimental Physics at Hamburg University. Prof. Hemmerich is a pioneer in the field of cold atoms, producing the first experimental demonstrations of 2D and 3D optical lattices, orbital lattices, and cold samples trapped in highfinesse optical cavities, among other milestones in the field. He has coauthored many papers in the most influential journals, including, just in the last 8 years, 1 in Science, 4 in Nature Journals, 1 in the Proceedings of the Natural Academy of Sciences, and 11 in Physical Review Letters.
