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 کاملRenormalization in 1-D Quantum Mechanics: contact interactions
We have commemorated the 20th anniversary of the Wilson-Kogut review [14] by building a toy model of the W-K RG in one dimensional Quantum Mechanics... With it, we show (well, sort of) that the RG flow in the set of 1-dimensional finite range S matrices fullfilling S −k = QSkQ defines the known four parametric set of zero-range interactions.
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 کاملA non-perturbative method for time-dependent problems in quantum mechanics
A powerful method for calculating the eigenvalues of a Hamiltonian operator consists of converting the energy eigenvalue equation into a matrix equation by means of an appropriate basis set of functions. The convergence of the method can be greatly improved by means of a variational parameter in the basis functions determined by the principle of minimal sensitivity. In the case of the quartic a...
متن کاملQuantum contact interactions
The existence of several exotic phenomena, such as duality and spectral anholonomy is pointed out in one-dimensional quantum wire with a single defect. The topological structure in the spectral space which is behind these phenomena is identified.
