聚合体模膜的皱曲转变和平坦相

Crumpling transition and flat phase of polymerized phantom membranes

J. -P. Kownacki, D. Mouhanna

摘要:

使用非微扰重整化群方法重新审视聚合体模膜。这使得人们可以研究在任何内部尺寸D和嵌入尺寸d中的皱曲转变和低温平坦相,并确定较低的临界尺寸。在我们的近似下,发现物理膜的起皱相变是二级的。然而,不排除在最近的蒙特卡罗模拟中观察到的弱一阶行为。

英文摘要:

Polymerized phantom membranes are revisited using a nonperturbative renormalization group approach. This allows one to investigate both the crumpling transition and the low-temperature, flat, phase in any internal dimension D and embedding dimension d, and to determine the lower critical dimension. The crumpling phase transition for physical membranes is found to be of second order within our approximation. A weak first-order behavior, as observed in recent Monte Carlo simulations, is however not excluded.
