Effective Field Theory for the Heteronuclear Efimov Effect

摘要

I discuss recent results describing heteronuclear systems using effective field theory. I will focus on three-body systems with two identical particles that interact resonantly with a third particle. Specifically, I will consider recent calculations of universal scaling function that can be used to compute the temperature dependent recombination rate for positive scattering length and the inclusion of a finite effective range at zero temperature.
