Method for Extracting the Glueball Wave Function [PDF]
, 1997 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.

A new fermion Hamiltonian for lattice gauge theory [PDF]
Nuclear Physics B - Proceedings Supplements, 2002 We formulate Hamiltonian vector-like lattice gauge theory using the overlap formula for the spatial fermionic part, $H_f$. We define a chiral charge, $Q_5$ which commutes with $H_f$, but not with the electric field term. There is an interesting relation between the chiral charge and the fermion energy with consequences for chiral anomalies.

Comments on foliated gauge theories and dualities in 3+1d
SciPost Physics, 2021 We investigate the properties of foliated gauge fields and construct several foliated field theories in 3+1d that describe foliated fracton orders both with and without matter, including the recent hybrid fracton models.

Lieb-Schultz-Mattis, Luttinger, and 't Hooft - anomaly matching in lattice systems
SciPost Physics, 2023 We analyze lattice Hamiltonian systems whose global symmetries have 't Hooft anomalies. As is common in the study of anomalies, they are probed by coupling the system to classical background gauge fields.

Confinement, Chiral Symmetry Breaking and Continuum Limits in Quantum Link Models
, 1998 Using the example of compact U(1) lattice gauge theory we argue that quantum link models can be used to reproduce the physics of conventional Hamiltonian lattice gauge theories.

A Lattice Non-Perturbative Definition of an SO(10) Chiral Gauge Theory and Its Induced Standard Model [PDF]
, 2013 The standard model is a chiral gauge theory where the gauge fields couple to the right-hand and the left-hand fermions differently. The standard model is defined perturbatively and describes all elementary particles (except gravitons) very well. However,

Guided random walks for solving Hamiltonian lattice gauge theories [PDF]
Annals of Physics, 1984 Abstract Motivated by developments for many-particle quantum systems, a Monte Carlo method for solving Hamiltonian lattice gauge theories without fermions is presented in which a stochastic random walk is guided by a trial wave function. To the extent that a substantial portion of the local structure of the theory can be incorporated in the trial ...

Combinatorial quantization of the Hamiltonian Chern-Simons theory I [PDF]
, 1994 Motivated by a recent paper of Fock and Rosly \cite{FoRo} we describe a mathematically precise quantization of the Hamiltonian Chern-Simons theory. We introduce the Chern-Simons theory on the lattice which is expected to reproduce the results of the ...
