... The standard interpretation of quantum mechanics is that all of the information that can be known about the particle is derivable from the particle’s wavefunction. The way this information is obtained is by using the probability density function which is the product of the wavefunction and its compl ...

... Using a Gaussian basis would remove another source of imprecision in the present calculations, the replacement (3.8) of exchange operators with their Coulomb operator analogs. The result of V ( e ) operating on any Gaussian term can be put into closed form, so approximation (3.8) becomes unnecessary ...

The idea of wave mechanics leads naturally to assume the well-known relation E = ~ω in the specific form H = ~W , where H is the classical Hamiltonian of a particle and W is the dispersion relation of the sought-for wave equation. We derive the expression of H in a curved space-time with an electrom ...
