THE PHYSICS GRADUATE PROGRAM invites everyone to the seminar:
Física Atômica Experimental – Desafios e Soluções o caminho entre as pedras
Prof. Dr. Jorge Douglas Massayuki kondo – UFSC
In the light of the most recent developments in tunable lasers and different schemes of cooling and trapping atomic samples, we can witness a grow in research groups around the planet interested in such systems in several different applications. Among the possibilities are the extensive exploration in the realm of degenerate quantum gases like Bose-Einstein condensates and fermionic degenerate samples, research on quantum turbulence (vortex creation), solitons, atomtronic, information storage, quantum simulations, etc. Highly excited atomic states, called Rydberg states are ideals in system that need long range controllable interactions and due to its long life-time, allows several operations over the same sample in cold samples. The quantum character of such atomic system led us to the observation of quantum interferences between coupled photons to a variety of atomic states, resulting, as an example, to the slowdown of photons inside the cloud during a finite time. On this talk, I’ll discuss some of the research on this exotic state both in ultra-cold and hot samples, with attention to the challenges and solutions faced during the planning and design of this kind of experiments and stablish the grounds for the implantation of the experimental atomic physics lab at the physics department.
