摘 要: | We investigate the influence of the boundary condition on the short-time dynamic behaviour of the Ising-like phase transition in square-lattice fully frustrated (FF) XY models with periodic and fluctuating twist boundary conditions.The transition temperature Tc and the dynamic and static critical exponents z,2β/υ and υ are estimated for both cases using short-time dynamic scaling analysis.The results show that both models have the same critical exponents,indicating that the boundary condition has nearly no effect on the short-time dynamic behaviour of the FFXY model.
