Efimov physics with multiple spin substates — •Chris H Greene — Purdue University, West Lafayette, Indiana, USA

The Efimov effect for three particles has some novel features when each particle can reside in more than one degenerate spin substate.[1] In the context of Bose-Einstein condensation, such systems are referred to a spinor condensates, and we can similarly refer to this few-body analog as a spinor three-body problem. Some of the effects we predict for this system, in the regime of large scattering lengths, include the occurrence of multiple Efimov channels with multiple universal exponents, in addition to some multichannel spectral features.
