Splitting instability of cellular structures in the Ginzburg-Landau model under the feedback control
Hidetsugu Sakaguchi
We study numerically a Ginzburg-Landau type equation for micelles in two dimensions. The domain size and the interface length of a cellular structure are controlled by two feedback…
Proton decay from the isoscalar giant dipole resonance in Ni
M. Hunyadi, H. Hashimoto, T. Li +18
Proton decay from the 3 isoscalar giant dipole resonance (ISGDR) in Ni has been measured using the () reaction at a bombarding energy of 386 MeV to investigat…
Delocalization transition of a small number of particles in a box with periodic boundary conditions
Hidetsugu Sakaguchi
We perform molecular dynamics simulation of a small number of particles in a box with periodic boundary conditions from a view point of chaotic dynamical systems. There is a transi…
Scaling Relations of Viscous Fingers in Anisotropic Hele-Shaw Cells
Hidetsugu Sakaguchi, Kazutaka Noto
Viscous fingers in a channel with surface tension anisotropy are numerically studied. Scaling relations between the tip velocity v, the tip radius and the pressure gradient are inv…
Creation and Reproduction of Model Cells with Semipermeable Membrane
Hidetsugu Sakaguchi
A high activity of reactions can be confined in a model cell with a semipermeable membrane in the Schlögl model. It is interpreted as a model of primitive metabolism in a cell. We…
Soliton turbulences in the complex Ginzburg-Landau equation
Hidetsugu Sakaguchi
We study spatio-temporal chaos in the complex Ginzburg-Landau equation in parameter regions of weak amplification and viscosity. Turbulent states involving many soliton-like pulses…
