Dynamics of Langevin Simulations
This chapter reviews numerical simulations of quantum field theories based on stochastic quantization and the Langevin equation. The topics discussed include renormalization of finite stepsize algorithms, Fourier acceleration, and the relation of the Langevin equation to hybrid stochastic algorithms and hybrid Monte Carlo. Invited chapter to appear in the special supplement “Stochastic Quantiza...
متن کاملStochastic Spin Dynamics & Langevin-Landau-Gilbert Simulations
Here I discuss the dynamics of microscopic systems, primarily for spin models, in thermal equilibrium, where the temperature causes random forces or torques, which are in competition with a damping force. This includes summarizing Langevin dynamics and finding methods for integrating the Landau-Gilbert equation of micromagnetics in time, with damping & temperature. The goal is to understand how...
متن کاملLangevin dynamics simulations of polymer translocation through nanopores.
We investigate the dynamics of polymer translocation through a nanopore using two-dimensional Langevin dynamics simulations. In the absence of an external driving force, we consider a polymer which is initially placed in the middle of the pore and study the escape time tau(e) required for the polymer to completely exit the pore on either side. The distribution of the escape times is wide and ha...
متن کاملLangevin Dynamics Simulations of Macromolecules on Parallel Computers
A parallel algorithm is developed that allows eecient Langevin{dynamics simulations of macromolecular coils, which is the usual structure of synthetic polymers in solution and in bulk. Contrary to usual so{called spatial decomposition algorithms, we map the one{dimensional topology of the chain molecule on the parallel computer. The speedup of the algorithm is measured on diierent multi{process...
متن کاملCalibrated Langevin-dynamics simulations of intrinsically disordered proteins.
We perform extensive coarse-grained (CG) Langevin dynamics simulations of intrinsically disordered proteins (IDPs), which possess fluctuating conformational statistics between that for excluded volume random walks and collapsed globules. Our CG model includes repulsive steric, attractive hydrophobic, and electrostatic interactions between residues and is calibrated to a large collection of sing...
