Monte Carlo studies of a Finsler geometric surface model    [PDF]

Hiroshi Koibuchi, Hideo Sekino
This paper presents a new type of surface models constructed on the basis of Finsler geometry. A Finsler metric is defined on the surface by using an underlying vector field, which represents an in-plane tilt order. According to the orientation of the vector field, the Finsler length becomes dependent on both position and direction on the surface, and for this reason the parameters such as the surface tension and bending rigidity become anisotropic. These parameters make the surface non-spherical. To confirm that the model is well-defined, we perform Monte Carlo simulations under several isotropic conditions such as those given by random vector fields. The results are comparable to those of previous simulations of the conventional model, which is isotropic. It is also confirmed that a tubular phase appears when the vector field is constant.
