Many body physics with Ultracold Atoms


Registration Fee per Tutorial:

  • Meeting Attendee (Virtual or In-Person): $140
  • Students: $75
  • Non-meeting Attendee: $150

Who Should Attend?

Graduate students, post-docs, and faculty interested in learning about the state of the art and prospects in realizing novel many-body phenomena using ultracold neutral atoms. The tutorial will provide both theoretical background and a survey of experimental techniques. Participants with a background in condensed-matter physics will be introduced to the unique capabilities of cold-atom systems, special emphasis will be placed on connecting and contrasting the observables and control techniques available in condensed matter versus atomic systems.

Tutorial Description

In the past 20 years, ultracold atoms–Bose-Einstein condensates (BCSs) and degenerate Fermi gases (DFGs)–have become an established platform for studying many-body physics, and today new cold atom systems are emerging. While our framework for understanding many-body physics was inherited from solid-state systems, with its emphasis on collective phenomena, phase transitions and near-equilibrium physics, cold-atom experiments offer complementary features, pose distinct challenges, and often require new methodologies to interpret data. Key technical features of BECs and DFGs include the availability of bosons as well as fermions, tunability of interactions, and flexibility for optically trapping atoms in diverse lattice geometries.

In addition to discussing BEC and DFG experiments, this tutorial will explore two emerging cold atom systems: Rydberg tweezer arrays and atom-ensembles in optical cavities. Rydberg tweezer arrays provide a new pathway for bottom-up engineering of spin models, and in contrast with quantum gases, Rydberg atoms offer much stronger interactions with a finite range. Atom-ensembles in cavities can have effective infinite range interactions governed by the engineerable mode structure of the cavity.
