The Coupled Cluster Method in Hamiltonian Lattice Field Theory: SU(2) Glueballs
A. Wichmann, D. Schuette, B. C. Metsch +1
The glueball spectrum within the Hamiltonian formulation of lattice gauge theory (without fermions) is calculated for the gauge group SU(2) and for two spatial dimensions. The Hilb…
Improved Lattice Gauge Field Hamiltonian
Xiang-Qian Luo, Shuo-Hong Guo, H. Kröger +1
Lepage's improvement scheme is a recent major progress in lattice , allowing to obtain continuum physics on very coarse lattices. Here we discuss improvement in the Hamiltonia…
Improving the Lattice QCD Hamiltonian
Xiang-Qian Luo, Shuo-Hong Guo, Helmut Kroeger +1
Improvement of the Hamiltonian in lattice gauge theory is considered. We give explicit expressions for classical improvement and discuss also quantum corrections.
Method for Extracting the Glueball Wave Function
J. Liu, X. Q. Luo, X. Fang +4
We describe a nonperturbative method for calculating the QCD vacuum and glueball wave functions, based on an eigenvalue equation approach to Hamiltonian lattice gauge theory. There…
The Coupled Cluster Method in Hamiltonian Lattice Field Theory
D. Schütte, Zheng Weihong, C. J. Hamer
The coupled cluster or exp S form of the eigenvalue problem for lattice Hamiltonian QCD (without quarks) is investigated. A new construction prescription is given for the calculati…
Universality for SU(2) Yang-Mills Theory in (2+1)D
C. J. Hamer, M. Sheppeard, Zheng Weihong +1
The Green's Function Monte Carlo method of Chin et al is applied to SU(2) Yang-Mills theory in (2+1)D. Accurate measurements are obtained for the ground-state energy and mean plaqu…
