Asymptotic freedom at zero temperature in crystalline membranes

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.
