The effect of magnetic field h on the longitudinal susceptibility in a spin S = 1 / 2 exchange anisotropic three-dimensional Heisenberg antiferromagnet, is studied by the double-time Green’s function method within Tyablikov approximation. The calcu

The coupled-cluster method with the eigenvalue equations truncated according to the continuum limit is applied to the Hamiltonian lattice O(3) {sigma} model. The long wavelength approximation of the vacuum wave function and mass gaps are calculated u

We discuss how to extract the spectroscopy of quantum chromodynamics (QCD) in the pure gauge sector from the Hamiltonian lattice field theory approach. The recently developed truncated eigenvalue equation method is applied to the estimation of the sc

We investigate quantum chromodynamics in 2+1 dimensions (QCD 3 ) using the Hamiltonian lattice field theory approach. The long wavelength structure of the ground state, which is closely related to the confinement phenomenon, is analyzed and its vacuu

Using the variational method, we calculate the mass of the vector meson in the Hamiltonian lattice Schwinger model. Our results are consistent with the exact value in the continuum.

We discuss analytically the vacuum structure and chiral-symmetry breaking in 1+1 dimensional lattice QCD with naive and Wilson fermions, using a unitary transformation and the variational method developed recently. As an example, the chiral order par

The physical vacuum state and general expression for the Hamiltonian ofd+1 dimensional lattice gauge theory are given by incorporating the exact ground state of pure gauge theory and the variational fermion vacuum state. The applications toSU(2) andS

The Schwinger model with its naive lattice fermions and vacuum structure is investigated analytically using unitary transformation and the variational method in the Hamiltonian formalism. The authors calculate the fermion condensate (psi-bar psi) for
