Variable range random walk
Takashi Odagaki
Exploiting the coherent medium approximation, random walk among sites distributed randomly in space is investigated when the jump rate depends on the distance between two adjacent…
Self-organization of oscillation in an epidemic model for COVID-19
Takashi Odagaki
On the basis of a compartment model, the epidemic curve is investigated when the net rate of change of the number of infected individuals is given by an ellipse in the -…
Self-organized wavy infection curve of COVID-19
Takashi Odagaki
Exploiting the SIQR model for COVID-19, I show that the wavy infection curve in Japan is the result of fluctuation of policy on isolation measure imposed by the government and obey…
Exact Properties of SIQR model for COVID-19
Takashi Odagaki
The SIQR model is reformulated where compartments for infected and quarantined are redefined so as to be appropriate to COVID-19, and exact properties of the model are presented. I…
Dynamics of particle flips in two-dimensional quasicrystals
Michael Engel, Masahiro Umezaki, Hans-Rainer Trebin +1
The dynamics of quasicrystals is more complicated than the dynamics of periodic solids and difficult to study in experiments. Here, we investigate a decagonal and a dodecagonal qua…
Glass Formation and Crystallization of a Simple Monatomic Liquid
Tomoko Mizuguchi, Takashi Odagaki
A simple monatomic system in two dimensions with a double-well interaction potential is investigated in a wide range of temperature by molecular dynamics simulation. The system is…
