... in which the spatial part is a simple product state. Clearly, this state does not obey the anti-symmetrization postulate, and from a fundamental point of view it therefore cannot be right. It is true that as long as we only consider observables that commute with position, we shall not arrive at any ...

... One year after the 1925 formulation of the Schrödinger equation, Erwin Madelung demonstrated that a particular transformation of the wavefunction provides a means of recasting the equation into hydrodynamic form. The corresponding system is a shallow, inviscid fluid layer evolving under the action o ...
