Langevin thermostat for rigid body dynamics.
We present a new method for isothermal rigid body simulations using the quaternion representation and Langevin dynamics. It can be combined with the traditional Langevin or gradient (Brownian) dynamics for the translational degrees of freedom to correctly sample the canonical distribution in a simulation of rigid molecules. We propose simple, quasisymplectic second-order numerical integrators a...
متن کاملGyration Radius and Energy Study at Different Temperatures for Acetylcholine Receptor Protein in Gas Phase by Monte Carlo, Molecular and Langevin Dynamics Simulations
The determination of gyration radius is a strong research for configuration of a Macromolecule. Italso reflects molecular compactness shape. In this work, to characterize the behavior of theprotein, we observe quantities such as the radius of gyration and the average energy. We studiedthe changes of these factors as a function of temperature for Acetylcholine receptor protein in gasphase with n...
متن کاملNew Langevin and gradient thermostats for rigid body dynamics.
We introduce two new thermostats, one of Langevin type and one of gradient (Brownian) type, for rigid body dynamics. We formulate rotation using the quaternion representation of angular coordinates; both thermostats preserve the unit length of quaternions. The Langevin thermostat also ensures that the conjugate angular momenta stay within the tangent space of the quaternion coordinates, as requ...
متن کاملDynamics of Capture in the Restricted Three-Body Problem
We propose a new dynamical model for capture of irregular moons which identifies chaos as the essential feature responsible for initial temporary gravitational trapping within a planet’s Hill sphere. The key point is that incoming potential satellites get trapped in chaotic orbits close to “sticky” KAM tori in the neighbourhood of the planet, possibly for very long times, so that the chaotic la...
متن کاملSymbolic Dynamics in the Planar Three-body Problem
1.1. Description of Results. Consider the motion of three point masses, m1, m2, m3, in a plane under the influence of their mutual gravitational attraction. This motion can be described by a Hamiltonian dynamical system of three degrees of freedom. In this paper, symbolic dynamical methods will be used to prove the existence of solutions of this Hamiltonian system which exhibit certain interest...
