Reminder: UNM Physics & Astronomy Event: Dynamical fermionization

[events at unm.edu]

===========================================================================
Physics and Astronomy Colloquium Series, Department of Physics & Astronomy, UNM
===========================================================================

David is an atomic-physics experimentalist working on trapped neutral atoms for quantum information processing.  I think he is one of the best people to give an overview of the neutral atoms for quantum information processing, together with some details of his own work.

Title: Dynamical fermionization
Presenter: David Weiss, Penn State University
When: Friday, September 27, 2019, 3:30 pm
Where: Room 125, Dane Smith Hall
Directions: http://panda.unm.edu/findpanda/

Abstract: I will describe experiments with one-dimensional (1D) Bose gases, made with ultracold atoms trapped in tubes made from light. Because the 1D Bose gases we study are "integrable" many-body systems, they have infinite sets of conserved quantities, unlike the usual few (energy, momentum, angular momentum) that are conserved in non-integrable systems. I will describe how we measure the never-before-measured extra conserved quantities. In the process we observe "dynamical fermionization", where the momentum distribution of a strongly interacting 1D Bose gas transforms into that of a non-interacting Fermi gas. We also observe the dramatic behavior of bosonic-fermionic oscillations, which are what they sound like. Prior knowledge of cold atom experiments and integrable many-body systems will not be necessary to follow this talk.

Refreshments will be available before the colloquium, at 3:15 pm, in 
the lobby of Dane Smith Hall.
