Short-time critical dynamics of vector models with long-ranged interactions — •Sorin Marculescu¹, Yuan Chen², and Zhibing Li² — ¹Universität-GH Siegen, D-57068, BRD — ²Zhongshan University, Guangzhou 510275, China

The critical dynamics in the short-time regime of spatial d-dimensional n-vector models with long-ranged interactions decaying as the d + σ inverse power of the distance is studied by using the renormalization group approach. The initial slip scaling form of the correlation and response functions are derived and the relevant critical exponents are computed to second order in the є-expansion.
