Study on Origins of Reverse Lane Usage using Nagel-Schreckenberg Model
Toshihiro Noda, Yasuhiro Hieida, Shin-ichi Tadaki
On highways with two lanes, cars are requested to run on the slow lane and are allowed to run on the fast lane for overtaking. However, on real two-lane highways, we daily observe…
Fluctuation in e-mail sizes weakens power-law correlations in e-mail flow
Yoshitsugu Matsubara, Yasuhiro Hieida, Shin-ichi Tadaki
Power-law correlations have been observed in packet flow over the Internet. The possible origin of these correlations includes demand for Internet services. We observe the demand f…
A systematic way to find and construct exact finite dimensional matrix product stationary states
Yasuhiro Hieida, Tomohiro Sasamoto
We explain how to construct matrix product stationary states which are composed of finite-dimensional matrices. Our construction explained in this article was first presented in a…
Least Action Principle for the Real-Time Density Matrix Renormalization Group
Kouji Ueda, Chenglong Jin, Naokazu Shibata +2
A kind of least action principle is introduced for the discrete time evolution of one-dimensional quantum lattice models. Based on this principle, we obtain an optimal condition fo…
Effects of Bottlenecks on Vehicle Traffic
Syohei Yamamoto, Yasuhiro Hieida, Shin-ichi Tadaki
Traffic congestion is usually observed at the upper streams of bottlenecks such as tunnels. Congestion appears as stop-and-go waves and high density uniform flow. We perform simula…
Product Wave Function Renormalization Group: construction from the matrix product point of view
Kouji Ueda, Tomotoshi Nishino, Kouichi Okunishi +3
We present a construction of a matrix product state (MPS) that approximates the largest-eigenvalue eigenvector of a transfer matrix T, for the purpose of rapidly performing the inf…
