Three-body universality in ultracold p-wave resonant mixtures

ORAL

Abstract

We study three-body collisions within ultracold mixtures with resonant interspecies p-wave interactions. Our results for the three-body effective interaction strength and decay rate are crucial towards understanding the stability and lifetime of these dilute quantum fluids. On resonance, we find that a class of universal scattering pathways emerges, regardless of the details of the short-range interactions. This gives rise quite generally to a remarkable regime where three-body effective interactions dominate over both inelastic decay and two-body effective interactions. Additionally, we find a series of mass-ratio dependent trimer resonances further from resonance.
