According to a study from Okubo, Japan, "We investigate the critical short-time scaling of the two-dimensional lattice phi(4) field theory with a Langevin dynamics."
"Starting from a ''hot'' initial configuration but with a small magnetization, the critical initial increase of the magnetization is observed through which we determine the critical point. From the short-time relaxation dynamics of various quantities at the critical point obtained, the dynamic critical exponents theta, z and the static exponent beta/nu are evaluated," wrote T. Otobe and colleagues, Waseda University.
The researchers concluded: "In executing a Langevin simulation, an ...
