Mesoscopic Hamiltonian for Josephson traveling-wave parametric amplifiers
Mesoscopic Hamiltonian for Josephson traveling-wave parametric amplifiers
We present a theory describing parametric amplification in a Josephson junction embedded transmission line. We will focus on the process of four-wave mixing under the assumption of an undepleted pump. However, the approach taken is quite general, such that a different parametric process or the process under different assumptions is …
