The one-loop elastic coefficients for the Helfrich membrane in higher dimensions
J. A. Santiago, A. Zamora
Abstract
Using a covariant geometric approach we obtain the effective bending couplings for a 2-dimensional rigid membrane embedded into a (2+D)-dimensional Euclidean space. The Hamiltonian for the membrane has three terms: The first one is quadratic in its mean extrinsic curvature. The second one is proportional to its Gaussian curvature, and the last one is proportional to its area. The results we obtain are in agreement with those finding that thermal fluctuations soften the 2-dimensional membrane embedded into a 3-dimensional Euclidean space.
