Event Details & Abstract: 

The running of couplings plays a critical role in QED and QCD physics. And because the running usually occurs at relatively high energy scales, the related phenomena in particle physics can only be observed in very-high-energy colliders.  In this talk, we will show that in unitary quantum gases  the running of coupling constants can occur at very small energy scales, smaller than the degeneracy temperatures in some limits. We will discuss the thermodynamic consequences of this, recent experimental evidence for those and what  can be done in the future.
