The MCQST Colloquium Series features interdisciplinary talks given by visiting international speakers. The monthly colloquial covers topics spanning all MCQST research units and will be broadcasted live, being made available to audiences worldwide. The main goal of the series is to create the framework for idea exchange, to strengthen links with QST leading groups worldwide, as well as to act as an integral part of the local educational environment.

MCQST Colloquium: Jun Ye

On February 23rd 2021, we are excited to invite you to attend the colloquium offered by Jun Ye, Professor of Physics at JILA, National Institute of Standards and Technology, and University of Colorado.

A Fermi gas of molecules with tunable dipolar interactions

The advent of a degenerate Fermi gas of polar molecules sets the stage to explore novel many-body physics. We apply a precisely controlled electric field to tune the elastic dipolar interaction by orders of magnitude while suppressing reactive losses. Efficient dipolar evaporation leads to the onset of quantum degeneracy in two-dimensional optical traps. When the electric field is used to tune excited molecular rotational states into degeneracy with the scattering threshold, we observe sharp collision resonances that give rise to three orders-of-magnitude modulation of the chemical reaction rate. Using this resonant shielding, we realize a long lifetime for a bulk molecular gas with tunable interactions.
