Abstract

We present an efficient approach to studying the spectra and eigenstates for nonlinear models describing multiphoton processes. We obtain the exact explicit analytical expressions of all the energy spectra and eigenstates in terms of a parameter for a class of models describing two-mode multiphoton processes. The parameter is shown to be determined by the roots of a simple polynomial.

Eigenstates and spectrum for a class of models describing three-mode multiphoton processes

Ying Wu, Xiaoxue Yang

By using an efficient approach developed by us, we present explicit analytical expressions for all the eigenenergies and eigenstates in terms of a parameter lambda for a class of models describing three-mode multiphoton processes. The parameter lambda is shown to be determined by the roots of a simple polynomial. We also obtain the exact explicit analytical expressions of infinite eigenstates and eigenenergies without any unknown parameters.

We present an efficient approach to studying the spectra and eigenstates for the model describing interactions among five bosonic modes without using the assumption of the Bethe ansatz. The exact analytical results of all the eigenstates and eigenvalues are in terms of a parameter for a class of models describing five-mode multiphoton process.

EXACT EIGENSTATES AND SPECTRUM OF FOUR-MODE MIXING SYSTEM WITH MULTIPHOTON PROCESSES

Weibin Li, Jiali Yu, Jiahua Li

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.

We obtain the exact analytical results of all the eigenvalues and eigenstates for three kinds of models describing N-mode multiphoton process without using the assumption of the Bethe ansatz. The exact analytical results of all the eigenstates and eigenvalues are in terms of a parameter λ for three kinds of models describing N-mode multiphoton process. The parameter is shown to be determined by the roots of a polynomial and is solvable analytically or numerically. Moreover, these three kinds of models can be processed with the same procedure.
