Two exactly solvable second-quantized models, namely, a one-fermion-one-boson model and the four-point Hubbard model, are presented. The connection with quantum chaotic behavior is discussed.Received 4 February 1985DOI:https://doi.org/10.1103/PhysRevA.32.1232©1985 American Physical Society

The authors prove, by considering a simple, exactly solvable model, that quantum systems under external perturbations may display a chaotic motion analogous to the corresponding classical ones.
