Eigenvalue relation of the Heisenberg chain with various boundary conditions for the ground state
Abstract: We propose a new parametrization of the eigenvalues of transfer matrix in a quantum integrable model. Based on it, we obtain the exact solution of the system. By studying the distribution o...
