Abstract

We apply a new updating algorithm scheme to investigate the critical behavior of the two-dimensional ferromagnetic Ising model on a triangular lattice with nearest neighbour interactions. The transition is examined by generating accurate data for large lattices with L=8,10,12,15,20,25,30,40,50L=8,10,12,15,20,25,30,40,50. The spin updating algorithm we employ has the advantages of both metropolis and single-update methods. Our study indicates that the transition to be continuous at Tc=3.6403(2)T_c=3.6403(2). A convincing finite-size scaling analysis of the model yield ν=0.9995(21)\nu=0.9995(21), β/ν=0.12400(18)\beta/\nu=0.12400(18), γ/ν=1.75223(22)\gamma/\nu=1.75223(22), γ/ν=1.7555(22)\gamma'/\nu=1.7555(22), α/ν=0.00077(420)\alpha/\nu=0.00077(420) (scaling) and α/ν=0.0010(42)\alpha/\nu=0.0010(42)(hyperscaling) respectively. Estimates of present scheme yield accurate estimates for all critical exponents than those obtained with Monte Carlo methods and show an excellent agreement with their well-established predicted values.
