We study the nonlinear classical dynamics of an electron confined in a double-well potential and subjected to a spin?orbit coupling as well as a constant external magnetic field. It is shown that due to the spin?orbit coupling the energy can be transferred from the spin to the orbital degree of freedom. It is shown that depending on the strength of the spin?orbit coupling and the energy of the system, the electronic orbital motion undergoes a transition from the regular to the chaotic regime.
