Analyses of kinetic glass transition in short-range attractive colloids based on time-convolutionless mode-coupling theory
Takayuki Narumi, Michio Tokuyama
The kinetic glass transition in short-range attractive colloids is theoretically studied by time-convolutionless mode-coupling theory (TMCT). By numerical calculations, TMCT is sho…
Relaxation with long-period oscillation in defect turbulence of planar nematic liquid crystals
Takayuki Narumi, Yosuke Mikami, Tomoyuki Nagaya +3
Through experiments, we studied defect turbulence, a type of spatiotemporal chaos in planar systems of nematic liquid crystals, to clarify the chaotic advection of weak turbulence.…
Compressed Exponential Relaxation as Superposition of Dual Structure in Pattern Dynamics of Nematic Liquid Crystals
Takayuki Narumi, Fahrudin Nugroho, Junichi Yoshitani +3
Soft-mode turbulence (SMT) is the spatiotemporal chaos observed in homeotropically aligned nematic liquid crystals, where non-thermal fluctuations are induced by nonlinear coupling…
Memory function of turbulent fluctuations in soft-mode turbulence
Takayuki Narumi, Junichi Yoshitani, Masaru Suzuki +4
Modal relaxation dynamics has been observed experimentally to clarify statistical-physical properties of soft-mode turbulence, the spatiotemporal chaos observed in homeotropically…
Glassy dynamics in relaxation of soft-mode turbulence
Fahrudin Nugroho, Takayuki Narumi, Yoshiki Hidaka +3
The autocorrelation function of pattern fluctuation is used to study soft-mode turbulence (SMT), a spatiotemporal chaos observed in homeotropic nematics. We show that relaxation ne…
Size Dependence of Current-Voltage Properties in Coulomb Blockade Networks
Takayuki Narumi, Masaru Suzuki, Yoshiki Hidaka +1
We theoretically investigate the current-voltage (I-V) property of two-dimensional Coulomb blockade (CB) arrays by conducting Monte Carlo simulations. The I-V property can be divid…
Active Brownian Motion in Threshold Distribution of a Coulomb Blockade Model
Takayuki Narumi, Masaru Suzuki, Yoshiki Hidaka +2
Randomly-distributed offset charges affect the nonlinear current-voltage property via the fluctuation of the threshold voltage of Coulomb blockade arrays. We analytically derive th…
Spatial and temporal dynamical heterogeneities approaching the binary colloidal glass transition
Takayuki Narumi, Scott V. Franklin, Kenneth W. Desmond +2
We study concentrated binary colloidal suspensions, a model system which has a glass transition as the volume fraction of particles is increased. We use confocal microscopy to…
