Relaxation, the Boltzmann-Jeans Conjecture and Chaos
Naoko Nakagawa, Kunihiko Kaneko
Slow (logarithmic) relaxation from a highly excited state is studied in a Hamiltonian system with many degrees of freedom. The relaxation time is shown to increase as the exponenti…

A Dynamic Mechanism of Energy Conversion to a Mechanical Work
Naoko Nakagawa, Kunihiko Kaneko
We propose a dynamic mechanism of a molecular machine for energy conversion, by considering a simple model describing the dynamics of two components, the head and the chain. After…

Energy Absorption and Storage in a Hamiltonian System in Partial Contact with a Heat Bath
Naoko Nakagawa, Kunihiko Kaneko
To understand the mechanism allowing for long-term storage of excess energy in proteins, we study a Hamiltonian system consisting of several coupled pendula in partial contact with…
