Ladies and Gentlemen. Due to the coronavirus epidemic in Poland, the CTP PAS is operating in a limited way. In particular, until further notice the secretariat and the accountancy of the CTP PAS will be working only remotely. Contact with the administration is possible only by an e-mail. We are sorry for any inconvenience.

Colloquium details

Name Center for Theoretical Physics Colloquium
Title Phase uncertainty in the interferometry with Bose-Einstein condensate
Details

In the world's most accurate devices, interferometers, the quantity under investigation (gravitational wave amplitude, magnetic field, energy difference in atomic clocks, etc.) is imprinted to the phase difference in both arms of the interferometer. From the results of the measurements of the phase difference, the desired value is estimated.

During the colloquium I will tell you how interferometry is carried out in practice, using Bose-Einstein condensates. I will present the results of my collaboration with the experimental group of Philipp Treutlein from Basel, where, comparing a number of experiments with theory, we understood what factors currently limit precision in the system, how to improve it, and found new values of some atomic constants.

The colloquium in the remote form at ZOOM. Please ask the organizers for a link to the meeting.
