Angesprochen sind Studenten höherer Studienjahre, alle Interessenten und insbesondere alle Mitarbeiter der Fachgruppe Theoretische Physik.
Das Theoriekolloquium findet, wenn nicht explizit ausgewiesen, wie folgt statt:
Ort: SR 1.02, Von-Seckendorff-Platz 1
Zeit: 16:15 - 17:30

| 17.05.2017 | Prof. Chris Greene Department of Physics and Astronomy Perdue University, Indiana chgreene@purdue.edu Experimental capabilities with ultracold few-body systems continue to advance rapidly in a number of contexts. This talk will highlight two recent developments. First, the observation of butterfly Rydbergmolecules with kilodebye dipole moments (H. Ott's group in Kaiserslautern) opens the door to the possibility of observing interesting blockaded phases in one dimension. Second, experimental observations of heavy-heavy-light Efimov physics in a mixture of Cs and Li atoms (M. Weidemueller's and C. Chin's groups) have sparked in-depth theoretical studies that suggest intriguing new regimes where interference minima compete and intertwine with resonances in recombination. |

| 25.02.2016 | Christian Schilling University of Oxford christian.schilling@physics.ox.ac.uk Fermionic Exchange Symmetry: Quantifying its Influence beyond Pauli's Exclusion Principle The Pauli exclusion principle has a strong impact on the properties and the behavior of most fermionic quantum systems. Remarkably, even stronger restrictions on fermionic natural occupation numbers follow from the fermionic exchange symmetry. We develop an operationally meaningful measure which allows one to quantify the potential physical relevance of those generalized Pauli constraints beyond the well-established relevance of Pauli's exclusion principle. It is based on a geometric hierarchy induced by Pauli exclusion principle constraints. The significance of that measure is illustrated for a few-fermion model which also confirms such nontrivial relevance of the generalized Pauli constraints. |

Then I will show how the symmetry analysis allows one to figure out the prerequisites for the quantum ratchet transport to occur and next helps to predict the direction of this transport. Theoretical considerations will be illustrated with the experimental results obtained by measuring mobility of a Bose-Einstein condensate of rubi atoms loaded into different ac-driven optical potentials. Finally, some open problems and promising directions will be discussed." |

In my talk I will in particular address phenomena which occur due to the presence of spin and isospin degrees of freedom as a result of the honeycomb structure of the underlying graphene lattice." |
