... Allowed energies for the harmonic oscillator - 1 • If we have an expression for the wave function of a harmonic oscillator (outside module scope!), we can use Schrödinger’s equation to get the energy. • It can be shown that only certain energy levels are allowed – this is a further example of energ ...

Quantum Few-Body Systems

... Recent developments in the analysis of critically stable systems are discussed. The behavior of weakly bound states in many-particle systems as they approach the continuum threshold is analyzed in the framework of non--relativistic quantum mechanics. Under minor assumptions it is proved [1] that if ...

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.
