Diffusion of interface and heat conduction in the three-dimensional Ising model
Yusuke Masumoto, Shinji Takesue
We investigate the relationship between a diffusive motion of an interface, heat conduction, and the roughening transition in the three-dimensional Ising model. We numerically comp…
Two extensions of exact non-equilibrium steady states of a boundary driven cellular automaton
Atsuo Inoue, Shinji Takesue
Recently Prosen and Mejía-Monasterio (J. Phys. A: Math. Theor. 49 (2016) 185003) obtained exact nonequilibrium steady states of an integrable and reversible cellular automaton driv…
Characteristic power spectrum of the diffusive interface dynamics in the two-dimensional Ising Model
Yusuke Masumoto, Shinji Takesue
We investigate properties of the diffusive motion of an interface in the two-dimensional Ising model in equilibrium or nonequilibrium situations. We focused on the relation between…
Numerical Estimation of the Current Large Deviation Function in the Asymmetric Simple Exclusion Process with Open Boundary Conditions
Tetsuya Mitsudo, Shinji Takesue
We numerically study the large deviation function of the total current, which is the sum of local currents over all bonds, for the symmetric and asymmetric simple exclusion process…
A Symmetry Property of Momentum Distribution Functions in the Nonequilibrium Steady State of Lattice Thermal Conduction
Akira Ueda, Shinji Takesue
We study a symmetry property of momentum distribution functions in the steady state of heat conduction. When the equation of motion is symmetric under change of signs for all dynam…
Heat conduction in one-dimensional lattice dynamical systems far from equilibrium
Akira Ueda, Shinji Takesue
We study heat conduction in one dimensional lattice dynamical systems far from equilibrium. The Fermi-Pasta-Ulam model and the model are numerically compared to elucidate dif…
Power-law behavior in the power spectrum induced by Brownian motion of a domain wall
Shinji Takesue, Hisao Hayakawa, Tetsuya Mitsudo
We show that Brownian motion of a one-dimensional domain wall in a large but finite system yields a power spectrum. This is successfully applied to the totally asymmetri…
Transport Phenomena at a Critical Point -- Thermal Conduction in the Creutz Cellular Automaton --
K. Saito, S. Takesue, S. Miyashita
Nature of energy transport around a critical point is studied in the Creutz cellular automaton. Fourier heat law is confirmed to hold in this model by a direct measurement of heat…
Energy Transport in the Integrable System in Contact with Various Types of Phonon Reservoirs
K. Saito, S. Takesue, S. Miyashita
We study how energy transport in an integrable system is affected by the spectral densities of heat reservoirs. The model investigated here is the quantum harmonic chain whose both…
