Elasticity, Shape Fluctuations and Phase Transitions of Anisotropic Membranes
Dr. Leo Radzihovsky, Univ of Colorado
``Tethered surfaces'', which are two-dimensional generalizations of linear
polymer chains, have been the focus of a number of theoretical
investigations during the past ten years. Unlike conventional polymers,
which are always crumpled at any temperature, these objects at low
temperatures undergo conformational transitions to flat and tubule phases
characterized by long-range order in the normals and very large
fluctuations perpendicular to the average membrane orientation. Focussing
on the tubule phase, recently observed in large scale Monte Carlo
simulations, I will discuss these novel phases and describe transitions
