Non-perturbative flow equations from continuous unitary transformations
J. N. Kriel
The goal of this thesis is the development and implementation of a non-perturbative solution method for Wegner's flow equations. We show that a parameterization of the flowing Hami…

Non-perturbative flow equations from continuous unitary transformations
J. N. Kriel, A. Y. Morozov, F. G. Scholtz
We use a novel parameterization of the flowing Hamiltonian to show that the flow equations based on continuous unitary transformations, as proposed by Wegner, can be implemented th…
