DESCRIPTION:Two impurities in a Bose-Einstein condensate: from the Yukawa t
 o the Efimov attraction\nPascal Naidon (RIKEN\, Japan)\nThe properties of 
 two particles immersed in a Bose-Einstein condensate are investigated usin
 g a variational approach. These properties can be interpreted in terms of 
 a boson-mediated interaction. For a weak particle-boson attractive interac
 tion\, the two particles form two free attractive polarons that interact t
 hrough a weak boson-mediated Yukawa attraction. For suffciently strong int
 eractions\, the boson-mediated interaction turns into an Efimov attraction
  leading to the binding of the two particles and one boson into Efimov tri
 mers. It is found that these in-medium Efimov trimers exist for weaker int
 eractions than in vacuum.\nReference: P. Naidon\, Two impurities in a Bose
