DNA变性转变顺序的重正化基团测定

Renormalisation group determination of the order of the DNA denaturation transition

Jose Manuel Romero-Enrique, Francisco de los Santos, Miguel A. Munoz

摘要:

我们报告同质DNA的热变性过渡的性质,确定从重整化组分析的Peyrard-主教-Dauxois模型。我们的方法是基于一个类比的临界润湿的现象,比以前的定性比较更进一步,并表明过渡是连续的平均碱基对分离。然而,由于普遍的临界行为的范围似乎是非常狭窄的,数值观察到的变性转变可能看起来一阶,因为它已经在文献中报道。

英文摘要:

We report on the nature of the thermal denaturation transition of homogeneous DNA as determined from a renormalisation group analysis of the Peyrard-Bishop-Dauxois model. Our approach is based on an analogy with the phenomenon of critical wetting that goes further than previous qualitative comparisons, and shows that the transition is continuous for the average base-pair separation. However, since the range of universal critical behaviour appears to be very narrow, numerically observed denaturation transitions may look first-order, as it has been reported in the literature.
