The statistical mechanics of fluctuating surfaces plays an important role in a variety of physical systems, ranging from biological membranes to world sheets of strings in theories of fundamental interactions. In many applications it is a good approximation to assume that the surfaces possess no tension. Their statistical properties are then governed by curvature energies only, which allow for gigantic out-of-plane undulations. These fluctuations are the “entropic” origin of long-range repulsive forces in layered surface systems. Theoretical estimates of these forces for simple model surfaces are surveyed and compared with recent Monte Carlo simulations.

Spontaneous Symmetry Breakdown

The stability of the symmetric vacuum of a simple model involving two scalar fields is examined. If quantum corrections to the effective potential are included up to first order in [Formula: see text], it is found that under certain conditions the quantum corrections induce an instability in the symmetric vacuum. Possible implications of this result for other models, such as massless electrodynamics, are discussed.
