Later, progress in the theory of pseudopotentials was achieved along two distinctly different lines of development. 2.1.1 The Operator Approach The original problem adressed by pseudopotential theory is that of solving the Schrodinger equation (2.2) agenzia napoliNettetRecall that the time-independent Schrödinger equation ˆHψ(x) = Eψ(x) yields the allowed energies and corresponding wavefunctions. However, it does not tell us how the system evolves in time. It would seem that something is missing, since, after all, classical mechanics tells us how the positions and velocities of a classical system evolve in time. agenzia musicale rossetti

Nettetmax is the maximal value of the total energy. The total energy is constant if the system consid- ered is in a stationary state, i.e. the electrons do not change their positions in an atom. Since any potential energy is defined as a value to which one can add any constant value, it is reasonable to ac- cept that ε max = 0.
