  • Nonperturbative flow equations from running expectation values 
    Scholtz, F. G.   Bartlett, Bruce H.   Geyer, H. B. (American Physical Society (APS), 2003-08)
    We show that Wegner’s flow equations, as recently discussed in the Lipkin model, can be solved selfconsistently. This leads to a nonlinear differential equation which fully determines the order parameter as a function ...
  • Non-perturbative flow equations from continuous unitary transformations 
    Kriel, J. N.   Morozov, A. Y.   Scholtz, F. G. (Institute of Physics Publishing (IOP), 2005-01)
    We use a novel parametrization of the flowing Hamiltonian to show that the flow equations based on continuous unitary transformations, as proposed by Wegner, can be implemented through a nonlinear partial differential ...
