Simulations of lattice-gauge theory at finite temperature and the Columbia supercomputer for lattice QCD
We have developed two efficient algorithms for simulations of lattice guage theory: an improved heatbath algorithm for pure gauge theory and a heatbath algorithm for dynamical fermions. The Langevin simulation method for SU(3) gauge theory is studied in detail. The 16-processor supercomputer and Monte Carlo programs running on this computer are described. Lattice gauge theory at finite temperature is studied in detail via the Monte Carlo simulation on this supercomputer. A large loop method to measure the energy is presented. The latent heat associated with the deconfinement transition is computed to be {Delta}E/T{sup 4} = 3.23 {plus minus} 0.55, 2.22 {plus minus} 0.94 and 4.48 {plus minus} 0.77 on the 16{sup 3} {times} 6, 16x{sup 3} {times} 8 and 16{sup 3} {times} 10 lattices respectively.
