Enhanced two-photon blockade without cascade channel by Stark nonlinear coupling
Zu-Jian Ying, Hang-Hang Han
Two-photon blockade (TPB) besides the conventional one-photon blockade can control the photon at the level of individual quanta in the input-output measurements of light-matter cou…

Two-photon blockade without cascade channel in strong light-matter coupling
Hang-Hang Han, Zu-Jian Ying
We report a distinct two-photon blockade (termed as weak TPB) discovered in the strong-coupling regime of a parity-broken generalized quantum Rabi model, in addition to the other t…

Critical quantum metrology in a stabilized two-photon Rabi model
Zu-Jian Ying, Hang-Hang Han, Bo-Jian Li +2
We investigate a generalized quantum Rabi model (QRM) with two- and four-photon terms with respect to applications for non-linear critical quantum metrology. In the introduced mode…
