Time series analysis using persistent homology of distance matrix
Takashi Ichinomiya
The analysis of nonlinear dynamics is an important issue in numerous fields of science. In this study, we propose a new method to analyze the time series data using persistent homo…
Protein folding analysis using features obtained by persistent homology
Takashi Ichinomiya, Ippei Obayashi, Yasuaki Hiraoka
Understanding the protein folding process is an outstanding issue in biophysics; recent developments in molecular dynamics simulation have provided insights into this phenomenon. H…
Thermodynamic Characterization of Synchronization-Optimized Oscillator-Networks
Tatsuo Yanagita, Takashi Ichinomiya
We consider a canonical ensemble of synchronization-optimized networks of identical oscillators under external noise. By performing a Markov chain Monte Carlo (MCMC) simulation usi…
Power-law exponent of the Bouchaud-Mézard model on regular random network
Takashi Ichinomiya
We study the Bouchaud-Mézard model on a regular random network. By assuming adiabaticity and independency, and utilizing the generalized central limit theorem and the Tauberian the…
Wealth distribution on complex networks
Takashi Ichinomiya
We study the wealth distribution of the Bouchaud--Mézard (BM) model on complex networks. It has been known that this distribution depends on the topology of network by numerical si…
Bouchaud-Mézard model on a random network
Takashi Ichinomiya
We studied the Bouchaud-Mézard(BM) model, which was introduced to explain Pareto's law in a real economy, on a random network. Using "adiabatic and independent" assumptions, we ana…
Power-law distribution in Japanese racetrack betting
Takashi Ichinomiya
Gambling is one of the basic economic activities that humans indulge in. An investigation of gambling activities provides deep insights into the economic actions of people and shed…
Path-integral approach to the dynamics in sparse random network
Takashi Ichinomiya
We study the dynamics involved in a sparse random network model. We extend the standard mean-field approximation for the dynamics of a random network by employing the path-integral…
Frequency synchronization in random oscillator network
Takashi Ichinomiya
We study the frequency-synchronization of randomly coupled oscillators. By analyzing the continuum limit, we obtain the sufficient condition for the mean-field type synchronization…
Impurity-induced Ferromagnetism in Doped Triplet Excitonic Insulator
Takashi Ichinomiya
The theory of impurities in excitonic insulator is investigated in the light of the recent experiments on hexaborides. First, we study the bound state around the impurity and find…
