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…

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…

Resonantly enhanced superconductivity mediated by spinor condensates

Giacomo Bighin, Puneet A. Murthy, Nicolò Defenu +1

Achieving strong interactions in fermionic many-body systems is a major theme of research in condensed matter physics. It is well-known that interactions between fermions can be me…

Transport in p-wave interacting Fermi gases

Jeff Maki, Tilman Enss

The scattering properties of spin-polarized Fermi gases are dominated by p-wave interactions. Besides their inherent angular dependence, these interactions differ from their s-wave…

Bulk viscosity of resonantly interacting fermions in the quantum virial expansion

Keisuke Fujii, Tilman Enss

We consider two-component fermions with a zero-range interaction both in two and three dimensions and calculate the bulk viscosity for an arbitrary scattering length in the high-te…

Universal van der Waals Force Between Heavy Polarons in Superfluids

Keisuke Fujii, Masaru Hongo, Tilman Enss

We investigate the long-range behavior of the induced Casimir interaction between two spinless heavy impurities, or polarons, in superfluid cold atomic gases. With the help of effe…
