An alternative way to express a coherent state is via its wavefunction in the position representation, denote it with ψ α ( x) (it's worth stressing that here "position" is to be understood as an abstract ...
WebA good starting point for solving this problem is the Hartree-Fock (HF) method. This method approximates a N-body problem into N one-body problems where each electron evolves in the mean-field of the others. ...
