Introduction
Associate Professor Chris Hamer, in
collaboration with Professor Jaan Oitmaa, studies lattice models
in theoretical physics, at the interface between field theory and
statistical mechanics. We are particularly interested in Hamiltonian
lattice gauge theory, which may be explored using linked-cluster
series expansions, Quantum Monte Carlo simulations, or effective
Lagrangian techniques. The aim is to predict the properties of bound
states of quarks and gluons in QCD. We are engaged in developing
Path Integral Monte Carlo techniques for simulating these systems.
One particular focus concerns the finite-size scaling properties
of lattice systems, and what they can tell us about the effective
Lagrangian.
Dr Zheng Weihong is an ARC Senior Research
Associate with world-leading expertise in linked-cluster expansion
techniques.
Dr. Robert Bursill is a QEII Fellow,
expert in applications of the density matrix renormalisation group
(DMRG), who has also been helping in the development of Quantum
Monte Carlo codes.
Maria Samaras is finishing up her Ph.D.
thesis on the application of "forward-walking" Green's
function Monte Carlo techniques to Hamiltonian lattice gauge theory.
Mushtaq Loan is a Ph.D. student working
on 'improved Hamiltonians' for lattice gauge theory.
Pradeep Sriganesh is a Ph.D. student
working on state-of-the-art finite-lattice calculations for the
Schwinger model (quantum electrodynamics in one space dimension).
Tim Byrnes is a Ph.D. student working
with Dr. Bursill to develop advanced '4-block' DMRG codes, and applying
them to various lattice models, including lattice gauge theories.
