"The Effect of Thermal Fluctuations on the Problem of Euler Buckling Instability"
 Slideshow (PDF)
Renormalization techniques are used to study the effect of thermal fluctuations on the classical Euler buckling instability of a homogenous rod in 2 spatial dimensions. It is discovered that temperature has the effect of exponentially stiffening the rod, yielding a non-zero minimum critical force as a function of the length of the rod.
