Optically-trapped, ultra-cold gases of spin ½-up and spin ½-down 6Li atoms enable “designer” interactions, offering a versatile environment for simulating exotic quantum systems. I will discuss our latest measurements of hydrodynamic transport coefficients in the strongly interacting regime, where the cloud exhibits scale invariant, “nearly perfect” flow, analogous to that of a quark-gluon plasma, a state of matter at 2 trillion degrees that existed microseconds after the Big Bang. Then I will discuss measurements of information scrambling in the very weakly interacting regime, where the cloud behaves as a large spin lattice with effective long-range interactions.
The ZOOM link will be sent on Wednesday morning to the Physics Faculty, Graduate student, PDRA, and AP mailing lists. If you are not on one of those lists and are interested in attending, please email Suzanne Hallihan at email@example.com for the link.
