查询词典 periodic

In Chapter 4, Short-time dynamic behavior of two-dimensional fully frustrated XY model near the Ising-like phase-transition temperature is studied with resistively shunted junction dynamics. The transition temperature and the dynamic and static critical exponents are estimated under both a periodic boundary condition and a fluctuating twist boundary condition using the short-time dynamic scaling analysis.
