Carla Hermann, PhD student, presented the seminar: “Dipole Blockade effect and source of Rydberg atoms”

“Dipole Blockade effect and source of Rydberg atoms” was the title of the talk presented by Carla Hermann Avigliano, a PhD student of optics and quantum information division of our Center, at a seminar which was unanimously applauded by her tutors.

The seminar was given in the Alamiro Robledo Auditorium of the physical sciences and mathematics faculty as part of her 3 week trip to Chile to continue with the theoretical work that she is carrying out with Dr. Carlos Saavedra. On this occasion, she delivered a progress report on the experimental work that she is currently doing in Paris.

Carla explained that she is developing an experiment which allows to obtain a deterministic source of Rydberg atoms from a Bose-Einstein condensate, generated through a Niobium super conductive chip immersed in 4.2 ° Kelvin, an extremely cold environment where superconducting materials can be used. The fundamental idea is that this deterministic source can accelerate atoms, and thus provide them to other kinds of experiments that need them in a controlled manner.

So far the research has only yielded experimental results where one can make out several Rydberg energy levels close to the 60S1/2 (rubidium atoms) which are of interest to the researcher, to later concentrate on the Bose-Einstein condensate. Hermann hopes to publish these experimental results by the end of this year.
