    Hartree Ansatz Method: Fermion Antisymmetry & Product vs. Linear Combination

    How does the Hartree product not reflect the antisymmertic nature of Fermions? Why do you take a product rather than a linear combination of the basis functions to get the total wave function (a la LCAO method, i.e. Linear Combination of Atomic Orbitals)?

    Average Radius of a Unit Cell: Na

    What is the average radius for a unit cell, for example, for Na? Is it the average of the ionic radii for the different coordination numbers (weighting each coordination number the same)? Or would it be the covalent radii or something else?

    A couple basic quantum mechanics questions

    Hi, I have a couple hopefully quick questions about quantum mechanics: For a momentum eigenstate how does the wave function e^{\frac{2 \pi}{h}ixp_{x}} not violate the uncertainty principle? (since both p and x are present in the function) Also, when you rewrite the above as...
