Phase Transition of a Semiflexible Membrane in Two Dimensions

Jingu Hwang

We study a two-dimensional semiflexible membrane model whose formal Hamiltonian is given by $H[\varphi ]={\sum }_x(\Vert \nabla {\varphi }_x{\Vert }^2+N^{\lambda }|\Delta {\varphi }_x{|}^2)$, interpolating between the discr…
