Anderson orthogonality scaling in the Rabi-driven heavy Fermi polaron
Michael Rautenberg, Tobias Krom, Eugen Dizer +6
The Anderson orthogonality catastrophe (AOC) is a paradigmatic many-body phenomenon in which a local perturbation induces a macroscopic response of a Fermi sea. We probe signatures…
Fate of an impurity strongly interacting with a thermal Bose gas
Jiří Etrych, Sebastian J. Morris, Simon M. Fischer +7
We spectroscopically study mobile impurities immersed in a homogeneous bosonic bath (a box-trapped Bose gas), varying the bath temperature and the strength of impurity-bath interac…
Bosonic Functional Determinant Approach and its Application to Polaron Spectra
Moritz Drescher, Manfred Salmhofer, Tilman Enss
The functional determinant approach (FDA) is a simple method to compute exactly certain observables for ideal quantum systems and has been successfully applied to the Fermi polaron…
Medium-induced Interaction Between Impurities in a Bose-Einstein Condensate
Moritz Drescher, Manfred Salmhofer, Tilman Enss
We consider two heavy particles immersed in a Bose-Einstein condensate in three dimensions and compute their mutual interaction induced by excitations of the medium. For an ideal B…
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…
