My name is Juan Ramón González Álvarez. I studied physics and chemistry at UVIGO, worked for some scientific bodies such as ANQUE, did early research in biogeochemistry and hydrodynamics of rias at CSIC, but now work in a unified formulation of physics chemistry and biology. My last research can be found at academia.edu

Now just compute the average of $v^2$ and you will obtain $c^2$, which correspond to a Dirac particle moving at $\pm c$

comment Is the wave-particle duality a real duality?
@Danu Why do you attribute to me the references from other authors? As Weinberg mentions in his book what we measure at laboratory are particles. Fields are only tools. There is no problem with curved spacetimes. Only some people that pretends to obtain the concept of particle from a QFT on curved spacetime.

comment What is the physical interpretation of the density matrix in a double continuous basis $|\alpha\rangle$, $|\beta\rangle$?
@PiotrMigdal Excellent article! The idea of a joint probability makes sense. I will study it more.

comment Canonical Commutation Relations
@ArnoldNeumaier As I mentioned above the Hilbert space can be obtained from the phase space. The key here is that the Wigner & Moyal formulation continue to work for systems whose description is beyond the Hilbert space. We can construct Wigner functions for states outside a Hilbert space.
