英文摘要: The emergence of Efimov states in ultracold atomic systems is expected to have a universal behaviour, but a new experimental study defies this expectation, reporting a clear deviation around a narrow Feshbach resonance.(#br)Abstract(#br)Efimov physics is a universal phenomenon in quantum three-body systems. For systems with resonant two-body interactions, Efimov predicted an infinite series of three-body bound states with geometric scaling symmetry 1 . These Efimov states, first observed in cold caesium atoms 2 , have been recently reported in a variety of other atomic systems 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 . The intriguing prospect of a universal absolute Efimov resonance position across Feshbach resonances remains an open question....
