SUMMARY:Physics and Astronomy Colloquium – Dr. Han Pu
LOCATION:
DESCRIPTION:The Department of Physics and Astronomy invites you to a colloquium featuring Dr. Han Pu, Physics & Astronomy Department at Rice University. Dr. Pu will present his talk, “Strongly interacting cold atoms in one dimension”, Tuesday, October 10 at 4:10 pm in Webster 17.\n\nMeet for refreshments before the lecture at 3:45 – 4:10pm in the foyer on floor G above the lecture hall. \n\nAbstract: Quantum mechanics often manifests itself in counter-intuitive ways.  When an ensemble of ultra-cold atoms are squeezed into one-dimensional (1D) space and made to interact with each other very strongly, the quantum properties of the system become particularly pronounced.  On the other hand, strongly interacting many-body systems are notoriously difficult to study theoretically.  However, there are theoretical tricks one can use to study 1D strongly interacting systems. In this talk, I will discuss how a strongly interacting 1D system can be mapped to a weakly interacting one, which is amenable to perturbation calculations. I will also discuss a novel method we recently developed to calculate the correlation functions and momentum distribution of such systems, which exploits an interesting connection between 1D bosons/fermions and 1D anyons.
