Gases of ultracold atoms are well-suited to studies of non-equilibrium phenomena in many-body systems. Here, we study a two-component Fermi gas following an interaction quench across the normal to superfluid phase transition. Starting with a weakly attractive Fermi gas, interactions are jumped to unitarity, and we measure the subsequent dynamics as the gas approaches equilibrium. Both pair formation and condensation are resolved, along with their corresponding timescales. Interaction quenches also excite the Higgs amplitude mode revealing the pairing gap in a Fermi superfluid. Finally, I will give a brief update on the quantum gas microscope experiment being constructed at Swinburne.

About Australia - New Zealand Cold Atom Seminars

This new initiative hosts a seminar once a month for the Australia – New Zealand cold atom research community.  The purpose is to encourage and facilitate ongoing discussions and collaboration in the local community.  Talks should be less than 40 minutes in length to allow ample time for questions and discussion.

Seminars will be held on the last Friday of the month (except for December) at 1pm Melbourne time (which is normally 3pm New Zealand time).  While the primary format is online via Zoom, various institutions will host the seminar in local seminar rooms.  The Zoom link is https://uqz.zoom.us/j/88604569495

You can sign up for announcements for the seminars at this webpage:

Seminars are recorded, and past seminars can be accessed from this web page.
