Investigation of multiple-dynein transport of melanosomes by non-invasive force measurement using fluctuation unit
Shin Hasegawa, Takashi Sagawa, Kazuho Ikeda +2
Pigment organelles known as melanosomes disperse or aggregate in a melanophore in response to hormones. These movements are mediated by the microtubule motors kinesin-2 and cytopla…
Rocking ratchet based on F1-ATPase in the absence of ATP
Kumiko Hayashi, Hisatsugu Yamasaki, Mitsunori Takano
Bartussek, Hanggi and Kissner studied a rocking ratchet system, in which a Brownian particle is subject to an asymmetric periodic potential together with an oscillating force, and…
Temperature of a Hamiltonian system given as the effective temperature of a non-equilibrium steady state Langevin thermostat
Kumiko Hayashi, Mitsunori Takano
In non-equilibrium steady states (NESS) far from equilibrium, it is known that the Einstein relation is violated. Then, the ratio of the diffusion coefficient to the mobility is ca…
Violation of the fluctuation-dissipation theorem in a protein system
Kumiko Hayashi, Mitsunori Takano
We report the results of molecular dynamics simulations of the protein myosin carried out with an elastic network model. Quenching the system, we observe glassy behavior of a densi…
Linear response theory in stochastic many-body systems revisited
Kumiko Hayashi, Shin-ichi Sasa
The Green-Kubo relation, the Einstein relation, and the fluctuation-response relation are representative universal relations among measurable quantities that are valid in the linea…
Exact transformation of a Langevin equation to a fluctuating response equation
Takahiro Harada, Kumiko Hayashi, Shin-ichi Sasa
We demonstrate that a Langevin equation that describes the motion of a Brownian particle under non-equilibrium conditions can be exactly transformed to a special equation that expl…
