[Triumf-seminars] TRIUMF Seminar today at 11:00

[postmaster at admin.triumf.ca]

Date/Time: Thu 2006-11-30 at 11:00

Location:  Auditorium          

Speaker:   Gautam Rupak (North Carolina State University)

Title:     Hot Dilute Neutron Matter and Neutrino Interactions

Abstract: The equation of state for hot dilute neutron matter is model-independently calculated to the third order in a virial expansion, at densities and temperatures that are relevant for neutrino-neutron interactions in protoneutron stars.

A general formalism for neutron matter with spin polarization is derived using a low-energy effective field theory. The long-wavelength neutrino response is calculated from the virial expansion, and can serve as a benchmark for model calculations that are in current use. The results are also of interest in atomic systems near the Feshbach resonance where universal behavior is expected.

The speaker is a candidate for a research scientist position in the theory group. Stimulants available 15 minutes before the talk.
