HYBRID MONTE-CARLO SIMULATION OF POLYMER-CHAINS

We develop the hybrid Monte Carlo method for simulations of single off-lattice polymer chains. We discuss implementation and choice of simulation parameters in some detail. The performance of the algorithm is tested on models for homopolymers with short- or long-range self-repulsion, using chains with 16 less than or equal to N less than or equal to 512 monomers. Without excessive fine tuning, we find that the computational cost grows as N-2+z' with 0.64<z'<0.84. In addition, we report results for the scaling of the end-to-end distance, r(1N)similar to N-v(1n N)(-alpha).
