Fermions meet two bosons -- the heteronuclear Efimov effect revisited
Binh Tran, Michael Rautenberg, Manuel Gerken +7
In this article, we revisit the heteronuclear Efimov effect in a Bose-Fermi mixture with large mass difference in the Born-Oppenheimer picture. As a specific example, we consider t…
Scattering of two heavy Fermi polarons: resonances and quasibound states
Tilman Enss, Binh Tran, Michael Rautenberg +6
Impurities in a Fermi sea, or Fermi polarons, experience a Casimir interaction induced by quantum fluctuations of the medium. When there is short-range attraction between impuritie…
Theory of a resonantly interacting impurity in a Bose-Einstein condensate
Moritz Drescher, Manfred Salmhofer, Tilman Enss
We investigate a Bose-Einstein condensate in strong interaction with a single impurity particle. While this situation has received considerable interest in recent years, the regime…
Real-space dynamics of attractive and repulsive polarons in Bose-Einstein condensates
Moritz Drescher, Manfred Salmhofer, Tilman Enss
We investigate the formation of a Bose polaron when a single impurity in a Bose-Einstein condensate is quenched from a non-interacting to an attractively interacting state in the v…
