Phase transition of surface models with intrinsic curvature
H. Koibuchi, N. Kusano, A. Nidaira +2
It is reported that a surface model of Polyakov strings undergoes a first-order phase transition between smooth and crumpled (or branched polymer) phases. The Hamiltonian of the mo…

Nonvanishing string tension of elastic membrane models
Hiroshi Koibuchi, Nobuyuki Kusano, Atsusi Nidaira +1
By using the grand canonical Monte Carlo simulations on spherical surfaces with two fixed vertices separated by the distance L, we find that the second-order phase transition chang…

First-order phase transition of fixed connectivity surfaces
Hiroshi Koibuchi, Nobuyuki Kusano, Atsusi Nidaira +2
We report a numerical evidence of the discontinuous transition of a tethered membrane model which is defined within a framework of the membrane elasticity of Helfrich. Two kinds of…
