Abstract:
I develop an improved Hamiltonian for classical, Minkowski Yang-Mills theory, which evolves infrared fields with corrections from lattice spacing beginning at . I use it to investigate the response of Chern-Simons number to a chemical potential, and to compute the maximal Lyapunov exponent. Both quantities have small limits, but the values of the limits differ from those found under the unimproved Hamiltonian, indicating that the theory suffers from lattice artefacts which do not vanish in the small limit.Note:
