[Triumf-seminars] TRIUMF Theory Seminar today at 13:00

Tue Mar 25 05:00:43 PDT 2014

Date/Time: Tue 2014-03-25 at 13:00

Location:  Theory Room         

Speaker:   Eric Anderson (UNC)

Title:     Beating (on) the Quantum Many-body Problem with Statistics

Abstract: By discrete Hubbard-Stratonovich transformations, systems of strongly
interacting fermions with a broad range of interactions can be mapped onto
Ising-like models.  Focusing on the later as test cases, I will discuss a
surprisingly simple and efficient way to calculate their thermodynamics via
(modified) random sampling.  The approach is validated by calculations in
the 2D & 3D Ising models, as well as for resonantly interacting fermions in
3+1 dimensions.  Possible applications of this method to finite particle
systems will also be considered.
