Photon number cumulant expansion and generating function for photon added- and subtracted-two-mode squeezed states
LU Dao-ming, Hong-Yi Fan · Chinese Physics B · 2014
For the first time, we derive the photon number cumulant for two-mode squeezed state and show that its cumulant expansion leads to normalization of two-mode photon subtracted-squeezed states and photon added- squeezed states. We show that the normalization is related to Jacobi polynomial, so the cumulant expansion in turn represents the new generating function of Jacobi polynomial.
