无序介质中聚合物的密度涨落

Density fluctuations of polymers in disordered media

J. M. Deutsch, M. Olvera de la Cruz

摘要:

我们研究自我避免随机游动的环境中,网站被随机排除,在二维和三维。对于一个单一的聚合物链,我们研究的时间平均单体密度的统计,并表明,这些都很好地描述了多重分形统计。即使远离无序介质的逾渗转变,情况也是如此。我们调查解决方案的链在无序的环境中,并表明,统计不再是多重分形超出了解决方案的屏蔽长度。

英文摘要:

We study self avoiding random walks in an environment where sites are excluded randomly, in two and three dimensions. For a single polymer chain, we study the statistics of the time averaged monomer density and show that these are well described by multifractal statistics. This is true even far from the percolation transition of the disordered medium. We investigate solutions of chains in a disordered environment and show that the statistics cease to be multifractal beyond the screening length of the solution.
