Multiple pendulum and nonuniform distribution of average kinetic energy
Tetsuro Konishi, Tatsuo Yanagita
Multiple pendulums are investigated numerically and analytically to clarify the nonuniformity of average kinetic energies of particles. The nonuniformity is attributed to the syste…
Dynamically induced conformation depending on excited normal modes of fast oscillation
Yoshiyuki Y. Yamaguchi, Tatsuo Yanagita, Tetsuro Konishi +1
We present dynamical effects on conformation in a simple bead-spring model consisting of three beads connected by two stiff springs. The conformation defined by the bending angle b…
Exact expression for average kinetic energy of 2-dimensional freely jointed chain and a related model
Tetsuro Konishi, Tatsuo Yanagita
For a 2-dimensional freely jointed chain with 3 particles and a related model, the average and variance of the kinetic energies of each particle in thermal equilibrium are exactly…
Emergence of Quasi-equilibrium State and Energy Distribution for the Beads-spring Molecule Interacting with a Solvent
Tatsuo Yanagita, Tetsuro Konishi
We study the energy distribution during the emergence of a quasi-equilibrium (QE) state in the course of relaxation to equipartition in slow-fast Hamiltonian systems. A bead-spring…
Slow relaxation to equipartition in spring-chain systems
Tetsuro Konishi, Tatsuo Yanagita
In this study, one-dimensional systems of masses connected by springs, i.e., spring-chain systems, are investigated numerically. The average kinetic energy of chain-end particles o…
Apparent violation of equipartition of energy in constrained dynamical systems
Tetsuro Konishi, Tatsuo Yanagita
We propose a planar chain system, which is a simple mechanical system with a constraint. It is composed of masses connected by light links. It can be considered as a mode…
