摘要翻译:
在1+1维讨论了体心固体对固体生长模型的有限温度版本,包括二聚体的附着和分离。通过底层演化算子的谱间隙,数值研究了增长界面的动力学指数。后者的有限尺寸标度被发现受到标准表面张力项的影响,而表面张力项依赖于生长速率。在大规模模拟中观察到的生长行为也证实了这种非普适性。相比之下,粗糙指数在宽温度范围内保持稳健。

英文摘要:
A finite temperature version of body-centered solid-on-solid growth models involving attachment and detachment of dimers is discussed in 1+1 dimensions. The dynamic exponent of the growing interface is studied numerically via the spectrum gap of the underlying evolution operator. The finite size scaling of the latter is found to be affected by a standard surface tension term on which the growth rates depend. This non-universal aspect is also corroborated by the growth behavior observed in large scale simulations. By contrast, the roughening exponent remains robust over wide temperature ranges.
