Parametrically squeezed states of microwave magnons in yttrium iron garnet films
M. Kostylev, A. B. Ustinov, A. V. Drozdovskii +2
We demonstrate theoretically, and confirm experimentally, that nonlinear spin waves excited in thin yttrium iron garnet films are good candidates for squeezing vacuum quantum noise…

Probing a two-level system bath via the frequency shift of an off-resonantly-driven cavity
Thibault Capelle, Emmanuel Flurin, Edouard Ivanov +8
Although the main loss channel of planar microwave superconducting resonators has been identified to be related to an external coupling to a two-level system (TLS) bath, the behavi…
