Lanczos calculation of the spectrum of Hamiltonian lattice gauge theory.

Physical Review D, 1988
The use of a generalized Lanczos technique for the accurate diagonalization of lattice-gauge-theory Hamiltonians is explored. The starting ansatz wave function is a Gaussian one which solves the theory exactly in the weak-coupling limit.

Scales of Euclidean and Hamiltonian lattice gauge theory in three dimensions.

Physical Review D, 1996
The relationship between the couplings of Hamiltonian and Euclidean SU({ital N}) lattice gauge theory is determined for three space-time dimensions.

Correspondence between the Hamiltonian cycle problem and the quantum lattice gauge theory

Europhysics letters, 2023
We propose the correspondence between the Hamiltonian cycle (HC) problem in graph theory and the quantum lattice gauge theory (QZ2LGT) defined on the lattice dual to that graph.

Nonlocal Hamiltonian gauge theories and their connection with lattice Hamiltonians

Physical Review D, 1985
We introduce the concept of primitive Hamiltonian density for nonlocal Abelian gauge theories. We subsequently study the local limit both with respect to the continuum and with respect to a lattice structure introduced via hypercubic cells. The non-Abelian case is also discussed.

Improved Hamiltonians for lattice gauge theory with fermions

Physical Review D, 1994
Several improved Hamiltonians for lattice gauge theory with fermions are proposed. A test of the Schwinger model and some applications to QCD are presented. The results for the mass spectrum indicate that the use of the improved Hamiltonians gives better results.

Hamiltonian lattice gauge theories and the role of longitudinal modes [PDF]

Il Nuovo Cimento A, 1984
The time-independent residual gauge invariance of Hamiltonian lattice gauge theories is considered. The role of the longitudinal gluon is discussed in both Lagrangian and Hamiltonian lattice gauge theories.

Hamiltonian formulation of Wilson's lattice gauge theories

Physical Review D, 1975
Wilson's lattice gauge model is presented as a canonical Hamiltonian theory. The structure of the model is reduced to the interactions of an infinite collection of coupled rigid rotators. The gauge-invariant configuration space consists of a collection of strings with quarks at their ends. The strings are lines of non-Abelian electric flux.

Application of guided random walks to U(1)2 Hamiltonian lattice gauge theory.

Physical Review D, Particles and fields, 1987
In this paper we study U(1${)}_{2}$ Hamiltonian lattice gauge theory as a model application of a guided-random-walk algorithm. We numerically evaluate the mean plaquette, vacuum energy per plaquette, and plaquette-plaquette correlation functions using ...

Hamiltonian formulation of Palumbo's noncompact lattice gauge theory

Physical Review D, 1994
We analyze Palumbo's noncompact, manifestly gauge-invariant, lattice gauge theory. Via the transfer matrix we construct from Palumbo's action the corresponding Hamiltonian. In the classical continuum limit we recover the Kogut-Susskind Hamiltonian. We also study the confinement structure of the theory by computing the Wilson loop in the strong coupling
