... Heitler and F. London, in 1927, considered the simplest molecule, H2. They started from the wave function of two H atoms in the ground state and calculated the energy perturbation when the nuclei are at a distance R. If the wave function of the electrons is symmetric with respect to the position of ...

... In the first quantization, if I have a wavefunction with N particles, then the kinetic energy must be the sum of the N single-particle kinetic energies. If I have N + 2 particles, then the kinetic energy is a different operator, with N + 2 terms. On the other hand, in the second-quantization, the ki ...
