聚合体模膜中的一级相变

First order phase transitions in polymerized phantom membranes

K. Essafi, J. -P. Kownacki, D. Mouhanna

摘要:

在D-维聚合体模膜嵌入在d-维空间中发生的起皱到平坦的相变的非微扰研究使用的序参量的幂的字段扩展到8阶。我们得到临界维数dcr(D),它在D=4和D=2之间的任何地方将二阶区域与一阶区域分开。我们的方法强烈表明,发生在物理膜的相变是一阶与最近的数值模拟协议。

英文摘要:

The crumpled-to-flat phase transition that occurs in D-dimensional polymerized phantom membranes embedded in a d-dimensional space is investigated nonperturbatively using a field expansion up to order eight in powers of the order parameter. We get the critical dimension dcr(D) that separates a second order region from a first order one everywhere between D=4 and D=2. Our approach strongly suggests that the phase transitions that take place in physical membranes are of first order in agreement with most recent numerical simulations.
