We discuss the steady-state dynamics of interfaces with periodic boundary conditions arising from body-centered solid-on-solid growth models in 1+1 dimensions involving random aggregation of extended particles (dimers, trimers, ...,k-mers). Roughening exponents as well as width and maximal height distributions can be evaluated directly in stationary regimes by mapping the dynamics onto an asymmetric simple exclusion process with k-type of vacancies. Although for k≥2 the dynamics is partitioned into an exponentially large number of sectors of motion, the results obtained in some generic cases strongly suggest a universal scaling behavior closely following that of monomer interfaces.
我们讨论了在 1+1 维中具有体心固-固生长模型的周期性边界条件的界面的稳态动力学，其中涉及扩展粒子（二聚体、三聚体、...，k 聚体）的随机聚集。通过将动力学映射到具有 k 型空位的不对称简单排斥过程，可以在稳定状态下直接评估粗化指数以及宽度和最大高度分布。尽管对于 k≥2，动力学被分成了数量指数增长的运动区域，但在一些一般情况下得到的结果强烈表明存在一种普遍的标度行为，它与单体界面非常接近。
