Experimental observation of a dissipative phase transition in a multi-mode many-body quantum system
Jens Benary, Christian Baals, Erik Bernhart +3
We characterize the dissipative phase transition in a driven dissipative Bose-Einstein condensate of neutral atoms. Our results generalize the work on dissipative nonlinear Kerr re…
A Kapitza Pendulum for Ultracold Atoms
Jian Jiang, Erik Bernhart, Marvin Röhrle +4
We report on the experimental realization of a Kapitza pendulum for ultracold atoms. Using time-periodic attractive and repulsive Gaussian potentials, we create an effective trap f…
Stability analysis and attractor dynamics of 3D dark solitons with localized dissipation
Christian Baals, Alexandre Gil Moreno, Jian Jiang +2
We study the stability and the attractor dynamics of an elongated Bose-Einstein condensate with dark or grey kink solitons in the presence of localized dissipation. To this end, th…
The Talbot effect in the presence of interactions
Philipp Hoellmer, Jean-Sebastien Bernier, Corinna Kollath +3
We study both experimentally and theoretically, considering bosonic atoms in a periodic potential, the influence of interactions in a Talbot interferometer. While interactions decr…
Coherent perfect absorption of nonlinear matter waves
Andreas Müllers, Bodhaditya Santra, Christian Baals +6
Coherent perfect absorption is the complete extinction of incoming radiation by a complex potential in a physical system supporting wave propagation. The concept was proven for lin…
Nonlinear standing waves in an array of coherently coupled Bose-Einstein condensates
Christian Baals, Herwig Ott, Joachim Brand +1
Stationary solitary waves are studied in an array of linearly-coupled one-dimensional Bose-Einstein condensates (BECs) by means of the Gross-Pitaevskii equation. Solitary wave…
Measuring finite-range phase coherence in an optical lattice using Talbot interferometry
Bodhaditya Santra, Christian Baals, Ralf Labouvie +3
One of the important goals of present research is to control and manipulate coherence in a broad variety of systems, such as semiconductor spintronics, biological photosynthetic sy…
