Eigenstates and eigenergies of seven bosonic modes mixing models
七玻色模混和模型的本征态及本征值

We present the explicit analytical results of all the eigenstates and eigenvalues by using a parameter $\lambda$ without the assumption of Bethe ansatz for three different kinds of seven bosonic modes mixing models. It is shown that the parameter is determined by the roots of a simple polynomial.Besides, we also accurately obtain the explicit analytical expressions of infinite eigenstates and energies without any unknown parameter.
