Recent breakthroughs with Efimov and Rydberg physics
Experimental capabilities with ultracold few-body systems
continue to advance rapidly in a number of contexts. This talk will highlight
two recent developments. First, the observation of butterfly Rydberg
molecules with kilodebye dipole moments (H. Ott's group) opens the door to the
possibility of observing interesting blockaded phases in one dimension.
Second, experimental observations of heavy-heavy-light Efimov physics
in a mixture of Cs and Li atoms (M. Weidemueller's and C. Chin's groups)
have sparked in-depth theoretical studies that suggest intriguing new regimes
where interference minima compete and intertwine with resonances in recombination.
