Two-photon coupling via Josephson element II: Interaction dressing, cross-Kerr coupling, and limits of low-energy bosonic model
Eugene V. Stolyarov, V. L. Andriichuk, Andrii M. Sokolov
We study the interactions mediated by a symmetric superconducting quantum interference device (SQUID), their renormalizations, and the applicability of the anharmonic oscillator (b…

Two-photon coupling via Josephson element I: Breaking the symmetry with magnetic fields
E. V. Stolyarov, V. L. Andriichuk, Andrii M. Sokolov
We consider a coupling element based on a symmetric superconducting quantum interference device (SQUID) and show that it mediates a two-photon interaction. This and other inductive…
