Excited States of U(1) Lattice Gauge Theory from Monte Carlo Hamiltonian
A. Hosseinizadeh, G. Melkonyan, H. Kröger +2
We address an old problem in lattice gauge theory - the computation of the spectrum and wave functions of excited states. Our method is based on the Hamiltonian formulation of latt…
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.
The Massive Schwinger Model in a Fast Moving Frame
H. Jirari, H. Kröger, K. J. M. Moriarty +1
We present a non-perturbative study of the massive Schwinger model. We use a Hamiltonian approach, based on a momentum lattice corresponding to a fast moving reference frame, and e…
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…
The Massive Schwinger Model - a Hamiltonian Lattice Study in a Fast Moving Frame
Helmut Kröger, Norbert Scheu
We present a non-perturbative study of the massive Schwinger model. We use a Hamiltonian approach, based on a momentum lattice corresponding to a fast moving reference frame, and e…
Distribution Functions From Breit-Frame Regularisation
Helmut Kroger, Norbert Scheu
We suggest a new Hamiltonian lattice approach, using a regularisation motivated by deep inelastic scattering. We discuss the relation between distribution functions and the s…
