结晶膜中零温下的渐近自由度

Asymptotic freedom at zero temperature in crystalline membranes

E. I. Kats, V. V. Lebedev

摘要:

我们研究量子(零温度)的独立晶体膜,这是嵌入到三维空间的二维物体的长波长波动的影响。波动产生对数重整化的弹性和弯曲模量的膜。我们发现单圈的RG方程,以证明该系统是在“渐近自由”制度,即量子涨落不稳定的平膜相。

英文摘要:

We investigate effects of quantum (zero-temperature) long wavelength fluctuations of free standing crystalline membranes, that are two-dimensional objects embedded into three-dimensional space. The fluctuations produce logarithmic renormalization of elasticity and bending moduli of the membranes. We find one-loop RG-equations to demonstrate that the system is in the "asymptotic freedom" regime that is the quantum fluctuations destabilize the flat membrane phase.
