Nonperturbative Flow Equations from Running Expectation Values

Scholtz F.G. ; Bartlett B.H. ; Geyer H.B. (2003)

Article

Self-consistent implementation of the Wegner flow equations was demonstrated. This led to a nonlinear differential equation which determined the order parameter as a function of the dimensionless coupling constant. Reasonable results in both phases for finite system sizes and small enough coupling were obtained, while convergence to the exact results was found in the thermodynamic limit.
