Monte Carlo Hamiltonian of lattice gauge theory
F. Paradis, H. Kroger, X. Q. Luo +1
We discuss how the concept of the Monte Carlo Hamiltonian can be applied to lattice gauge theories.
Measure of the path integral in lattice gauge theory
F. Paradis, H. Kroger, X. Q. Luo +1
We show how to construct the measure of the path integral in lattice gauge theory. This measure contains a factor beyond the standard Haar measure. Such factor becomes relevant for…
The Use of the Monte Carlo Hamiltonian
H. Kröger, X. Q. Luo, K. J. M. Moriarty
In order to solve quantum field theory in a non-perturbative way, Lagrangian lattice simulations have been very successful. Here we discuss a recently proposed alternative Hamilton…
Thermodynamics from Monte Carlo Hamiltonian
L. A. Caron, H. Kröger, G. Melkonyan +2
We construct an effective low-energy Hamiltonian from the classical action via Monte Carlo with importance sampling. We use Monte Carlo (i) to compute matrix elements of the transi…
Parallel Computing for QCD on a Pentium Cluster
X. Q. Luo, E. B. Gregory, J. C. Yang +3
Motivated by the computational demands of our research and budgetary constraints which are common to many research institutions, we built a ``poor man's supercomputer'', a cluster…
