Perturbative Renormalization in Quantum Mechanics
Some quantum mechanical potentials, singular at short distances, lead to ultraviolet divergences when used in perturbation theory. Exactly as in quantum field theory, but much simpler, regularization and renormalization lead to finite physical results, which compare correctly to the exact ones. The Dirac delta potential, because of its relevance to triviality, and the AharonovBohm potential, be...
متن کاملAn Alternative Perturbative Expansion in Quantum Mechanics . Scaling and Cut - off Resummation
An alternative perturbative expansion in quantum mechanics which allows a full expression of the scaling arbitrariness is introduced. This expansion is examined in the case of the anharmonic oscillator and is conveniently resummed using a method which consists in introducing an energy cutoff that is carefully removed as the order of the expansion is increased. We illustrate this technique numer...
متن کاملPerturbative renormalizations of anyon quantum mechanics.
In bosonic end perturbative calculations for quantum mechanical anyon systems a regularization and renormalization procedure, analogous to those used in eld theory, is necessary. I examine the reliability and the physical interpretation of the most commonly used bosonic end regularization procedures. I then use the regularization procedure with the most transparent physical interpretation to de...
متن کاملPerturbative expansion of Chern-Simons theory
We give an overview of the perturbative expansion of the ChernSimons path integral. The main goal is to describe how trivalent graphs appear: as they already occur in the perturbative expansion of an analogous finite-dimensional integral, we discuss this case in detail.

متن کاملMinimal Irreversible Quantum Mechanics: Pure States Formalism
It is demonstrated that, making minimal changes in ordinary quantum mechanics, a reasonable irreversible quantum mechanics can be obtained. This theory has a more general spectral decompositions, with eigenvectors corresponding to unstable states that vanish when t → ∞. These ”Gamov vectors” have zero norm, in such a way that the norm and the energy of the physical states remain constant. The e...
