- Atomic Physics Seminar
- Extending the quantum domain with quantum optics
- Time: 10:00 am
- Place: 5310 Chamberlin Hall
- Speaker: Christoph Simon, University of Calgary
- Abstract: Quantum optical systems are well suited for pushing the boundaries of quantum physics. Two big goals in this context are the creation of entanglement over long distances and the observation of quantum effects on macroscopic scales. I will describe various theoretical and some experimental work in these directions. In particular I am planning to discuss quantum repeaters with multimode quantum memories, the potential for global entanglement using satellite links and repeaters, work towards the quantum non-demolition detection of photonic qubits in rare-earth doped crystals, ideas on photon-photon gates based on Rydberg states, an experiment creating micro-macro entanglement of light, and a proposal for spin cat states in Bose-Einstein condensates.

- Hydrodynamic Coulomb and Hall drag of strongly correlated electron liquids
- Time: 10:00 am - 11:00 am
- Place: Chamberlin 5310
- Speaker: Alex Levchenko, Michigan State University
- Abstract: We develop a theory of drag resistivity in ultraclean double layers with strongly correlated carriers. In the regime where the equilibration length of the electron liquid is shorter than the interlayer spacing the main contribution to the drag arises from hydrodynamic density fluctuations. The latter consist of plasmons driven by fluctuating longitudinal stresses, and diffusive modes caused by temperature fluctuations and thermal expansion of the electron liquid. We express the drag resistivity tensor in terms of the kinetic coefficients of the electron fluid. Our results are nonperturbative in interaction strength and do not assume Fermi-liquid behavior of the electron liquid.
