... Nowadays, a proper semiclassical treatment of the helium atom is still an outstanding problem of semiclassical theory. This is due to the fact that the Hamiltonian contains at least three non-separable degrees of freedom. As we will show, the classical phase space of the two-electron system is of mi ...

A foundational approach to the meaning of time reversal

Some [2] have proposed that the guidance equation be derived from the demand of Galilei invariance. However, this technique presupposes a particular mea ...
