Non-reciprocical Scattering in a Microwave Frequency Comb
Non-reciprocical Scattering in a Microwave Frequency Comb
We investigate non-reciprocal scattering within the modes of a microwave frequency comb. Adjusting the pump frequencies, amplitudes, and phases of a Josephson parametric oscillator, we control constructive interference for the $m \longrightarrow \ell$ scattering processes, while concurrently achieving destructive interference for the inverse process $\ell \longrightarrow m$. We outline the …
