摘要翻译:
采用Kardar-Parisi-Zhang方程定义的界面位移模型,加上一些表示极限短程吸引壁的附加项,对非平衡条件下的临界润湿转变进行了数值和解析研究。它的临界行为通过在一维中提供平均高度和表面序参量的一组指数来详细描述。新出现的图像在定性和定量上都不同于最近报道的对同一问题的平均场预测。有证据表明,吸引壁的存在导致了界面局部坡度的异常缩放。

英文摘要:
Critical wetting transitions under nonequilibrium conditions are studied numerically and analytically by means of an interface-displacement model defined by a Kardar-Parisi-Zhang equation, plus some extra terms representing a limiting, short-ranged attractive wall. Its critical behavior is characterized in detail by providing a set of exponents for both the average height and the surface order-parameter in one dimension. The emerging picture is qualitatively and quantitatively different from recently reported mean-field predictions for the same problem. Evidence is shown that the presence of the attractive wall induces an anomalous scaling of the interface local slopes.
