Physics and Astronomy Colloquium

[Ivan Deutsch]

Dear Colleagues and Students,

I am pleased to welcome Prof. David Weiss, Penn State University, who will deliver this week’s Physics & Astronomy Colloquium, Friday Sept. 27.  Prof. Weiss is leader in cold atom physics, with applications to fundamental many-body physics and applications in quantum computing.  Below is the title and abstract of his colloquium.

Dynamical fermionization
Friday September 27, 2019
3:30 pm


 Presenter:     David Weiss, Penn State University
 Series:        Physics and Astronomy Colloquium<http://physics.unm.edu/pandaweb/events/index.php?display=series&series_id=6>
 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.

 Location:      Room 125, Dane Smith Hall

Refreshments will be available before the colloquium, at 03:15 pm, in in the lobby of Dane Smith Hall.

[Disability Notice]Individuals with disabilities who need an auxiliary aid or service to attend or participate in P&A events should contact Sandra Ortiz (phone: 505-277-5900, email: sportiz at unm.edu<mailto:sportiz at unm.edu>) well in advance to ensure your needs are accommodated. Event handouts can be provided in alternative accessible formats upon request. Please contact Ms. Ortiz if you need written information in an alternative format.


He will also deliver the CQuIC seminar on Thursday, spet. 26.  If you would like to meet with Prof. Weiss Thursday or Friday, please contact Pablo Poggi <ppoggi at unm.edu<mailto:ppoggi at unm.edu>>, the CQuIC postdoc who coordinates our seminar.
