Pauli Blocking Effect on Efimov States Near Feshbach Resonance
arXiv:1011.0006 · doi:10.1103/PhysRevLett.106.145301
Abstract
In this Letter we study the effect of Pauli blocking on the Efimov states in a quantum Fermi gas and illustrate that the universal Efimov potential is altered at large distances. We obtain the universal spectrum flow of Efimov trimers when the Fermi density is varied and further consider the effect of scattering of trimers by the Fermi sea. We argue that the universal flow is robust against fluctuating particle-hole pairs that result in an infrared catastrophe in impurity problems.
