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…
Mass-gap functional determinant approach for mobile Fermi polarons
Emilio Ramos Rodríguez, Eugen Dizer, Xin Chen +1
We extend the functional determinant approach (FDA), previously restricted to static impurities, to the case of finite-mass impurities by using the mass-gap description of Fermi po…
Tunable state-dependent interactions in collisionally stable mixtures of polar molecules
Hubert J. Jóźwiak, Hanwei Yang, Eugen Dizer +2
We propose encoding a pseudo-spin- system in the ground () and first excited () vibrational states of polar molecules. Double microwave shielding simultaneously shie…
Mass-gap description of heavy impurities in Fermi gases
Xin Chen, Eugen Dizer, Emilio Ramos Rodríguez +1
We present a unified theory that connects the quasiparticle picture of Fermi polarons for mobile impurities to the Anderson orthogonality catastrophe for static impurities. By oper…
Spectral properties and observables in ultracold Fermi gases
Eugen Dizer, Jan Horak, Jan M. Pawlowski
We calculate non-perturbative self-consistent fermionic and bosonic spectral functions of ultra-cold Fermi gases with the spectral functional approach. This approach allows for a d…
