EXACT EIGENSTATES AND SPECTRUM OF FOUR-MODE MIXING SYSTEM WITH MULTIPHOTON PROCESSES
Weibin Li, Jiali Yu, Jiahua Li
Abstract
The authors propose explicit analytical results for energy eigenstates and eigenvalues for a class of models describing four-mode mixing with multiphoton processes that can be described resorting to a single parameter. The value of such parameter is determined by the roots of a polynomial and can be determined either analytically or numerically.
