... The “fine structure” corrections to the hydrogen spectrum all arise from relativistic corrections. There are three di↵erent relativistic e↵ects that we need to take into account: we will treat the first here, and the others in Sections 7.1.3 and 7.1.4 You can run into difficulties if you naively try ...

The electron obeys Coulomb's law of classical electromagnetic theory, and yet it is assumed to not radiate, as it would classically. These postulates may result in good predictions for the hydrogen atom, but they lack a solid funda ...

The notion of an experiment (observation) is a key concept in understanding quantum mechanics: only by conducting an experiment one can localize a particle with probabilities calculated from ψ ( q ) . Before an experiment is conducted, the particle cannot be said to be at a given coordinate. But nei ...

Choosing λ0 = 0 and λ1 = λ , the coupling Hamiltonian reduces to a very simple form HCoup = λ nL , which results into the effective Hamiltonians for each component of the systems, H0 = HE and H1 = HE (α → α + λ ).

Perturbation theory (quantum mechanics)

In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one. The idea is to start with a simple system for which a mathematical solution is known, and add an additional ""perturbing"" Hamiltonian representing a weak disturbance to the system. If the disturbance is not too large, the various physical quantities associated with the perturbed system (e.g. its energy levels and eigenstates) can be expressed as ""corrections"" to those of the simple system. These corrections, being small compared to the size of the quantities themselves, can be calculated using approximate methods such as asymptotic series. The complicated system can therefore be studied based on knowledge of the simpler one.
