Analytical Results of Eigenstates and Eigenenergies for a Classical Model of Many Bosonic Modes Mixing
Wen‐Xing Yang, Jiahua Li, Zhiming Zhan +1 more
The analytical expressions of eigenstates and eigenenergies are demonstrated using a parameter λ without the assumption of Bethe anstz for two kinds of N-mode mixing models. The parameter is shown to be determined by the roots of a simple polynomial and is solvable analytically or numerically. In addition, the exact analytical expressions of eigenstates and eigenenergies are illustrated without any unknown parameter.
