Loss of Causality in Discretized Light-Cone Quantisation
T. Heinzl, H. Kröger, N. Scheu
We demonstrate that front form quantisation with periodicity in a compact light-like direction (discretized light-cone quantisation) violates microcausality.

On the Computation of Mass Spectra and Structure Functions in a Relativistic Hamiltonian Formalism: A Lattice Point of View
Norbert Scheu
Herein we propose a new numerical technique for solving field theories: the large momentum frame (LMF). This technique combines several advantages of lattice gauge theory with the…

Computation of Structure Functions From a Lattice Hamiltonian
Helmut Kroger, Norbert Scheu
We compute structure functions in the Hamiltonian formalism on a momentum lattice using a physically motivated regularisation that links the maximal parton number to the lattice si…
