No.Let's say the energy or the Hamiltonian operator has 10 Gev defined for the entire quantum state. Does it mean each term (or branches) would have 5 Gev?
They don't. You apply an operator to the quantum state, not to parts of it. So it's meaningless to ask what the energy of just one branch is.How do the branches partition the energy?
You can use any energy units you like. GeV is a perfectly valid energy unit.what is the right unit for energy (instead of Gev)
