非平衡润湿模型的数值研究

Numerical study of a model for non-equilibrium wetting

A. C. Barato, H. Hinrichsen, M. J. de Oliveira

摘要:

我们重新审视非平衡润湿模型的缩放特性[物理学评论快报。79,2710(1997)],校正了临界指数的先前估计并提供了完整的缩放方案。此外,我们研究了相图中的一个特殊点,在那里模型表现出与定向渗流有关的粗糙化过渡。我们认为,在这一点附近的蒸发从高原中部可以被解释为一个外部领域的语言定向渗透。这个类比使我们能够计算交叉指数,并预测接近其端点的相变线的形式。

英文摘要:

We revisit the scaling properties of a model for non-equilibrium wetting [Phys. Rev. Lett. 79, 2710 (1997)], correcting previous estimates of the critical exponents and providing a complete scaling scheme. Moreover, we investigate a special point in the phase diagram, where the model exhibits a roughening transition related to directed percolation. We argue that in the vicinity of this point evaporation from the middle of plateaus can be interpreted as an external field in the language of directed percolation. This analogy allows us to compute the crossover exponent and to predict the form of the phase transition line close to its terminal point.
