Role of thermal two-phonon scattering for impurity dynamics in a low-dimensional BEC
Tobias Lausch, Artur Widera, Michael Fleischhauer
We numerically study the relaxation dynamics of a single, heavy impurity atom interacting with a finite one- or two-dimensional, ultracold Bose-gas. While there is a clear separati…
Prethermalization in the cooling dynamics of an impurity in a BEC
Tobias Lausch, Artur Widera, Michael Fleischhauer
We discuss the cooling dynamics of heavy impurity atoms in a Bose-Einstein condensate (BEC) by emission of Cherenkov phonons from scattering with the condensate. In a weakly intera…
Extreme Event Statistics in a Drifting Markov Chain
Farina Kindermann, Michael Hohmann, Tobias Lausch +3
We analyse extreme event statistics of experimentally realized Markov chains with various drifts. Our Markov chains are individual trajectories of a single atom diffusing in a one…
