Effective Quantization of Lossy Nonlinear Epsilon-Near-Zero Media
Avishi Poddar, Jonas von Milczewski, Durdu O. Guney +2
In epsilon-near-zero (ENZ) materials, the vanishing real linear permittivity results in the leading-order contribution to the displacement field being nonlinear in the electric fie…

Momentum-dependent quasiparticle properties of the Fermi polaron from the functional renormalization group
Jonas von Milczewski, Richard Schmidt
We study theoretically the lifetimes of attractive and repulsive Fermi polarons, as well as the molecule at finite momentum in three dimensions. To this end, we develop a new techn…

Superconductivity induced by strong electron-exciton coupling in doped atomically thin semiconductor heterostructures
Jonas von Milczewski, Xin Chen, Atac Imamoglu +1
We study a mechanism to induce superconductivity in atomically thin semiconductors where excitons mediate an effective attraction between electrons. Our model includes interaction…
