Analysis of the Chaotic Itinerancy Phenomenon using Entropy and Clustering

Nikodem Mierski, Pawe{l} Pilarczyk ยท 2025

We introduce a new methodology for the analysis of the phenomenon of chaotic itinerancy in a dynamical system using the notion of entropy and a clustering algorithm. We determine systems likely to expโ€ฆ

Stochastically bistable growth and decay in the Togashi-Kaneko model

Jeremy R. Worsfold, Richard G. Morris ยท 2025

The two-state Togashi-Kaneko model demonstrates how, at finite system sizes, autocatalysis can lead to noise-induced bistability between the cellular concentrations of different molecular species. Herโ€ฆ

Covariant Radiative Transfer for Black Hole Spacetimes

Shane W. Davis, Charles F. Gammie ยท 2019

It has now become possible to study directly, via numerical simulation, the evolution of relativistic, radiation-dominated flows around compact objects. With this in mind we set out explicitly covariaโ€ฆ

Photoinduced electron-electron pairing in the extended Falicov-Kimball model

Ryo Fujiuchi, Tatsuya Kaneko, Yukinori Ohta, Seiji Yunoki ยท 2019

By employing the time-dependent exact diagonalization method, we investigate the photoexcited states of the excitonic insulator in the extended Falicov-Kimball model (EFKM). We here show that the pulsโ€ฆ

Toric geometry and regularization of Feynman integrals

Konrad Schultka ยท 2018

We study multivariate Mellin transforms of Laurent polynomials by considering special toric compactifications which make their singular structure apparent. This gives a precise description of their coโ€ฆ

Resurgence analysis of 2d Yang-Mills theory on a torus

Kazumi Okuyama, Kazuhiro Sakai ยท 2018

We study the large $N$ 't Hooft expansion of the partition function of 2d $U(N)$ Yang-Mills theory on a torus. We compute the $1/N$ genus expansion of both the chiral and the full partition function oโ€ฆ

Simple model of photo acoustic system for greenhouse effect

Akiko Fukuhara, Fumitoshi Kaneko, Naohisa Ogawa ยท 2010

The green house effect is caused by the gases which absorb infrared ray (IR) emitted by the earth. It is worthwhile if we can adjudicate on which gas causes the greenhouse effect in our class. For thiโ€ฆ
