Thermoelectricity modeling with cold dipole atoms in Aubry phase of optical lattice
Oleg V. Zhirov, José Lages, Dima L. Shepelyansky
We study analytically and numerically the thermoelectric properties of a chain of cold atoms with dipole-dipole interactions placed in an optical periodic potential. At small poten…
Dynamical environments of relativistic binaries: The phenomenon of resonance shifting
Ivan I. Shevchenko, Guillaume Rollin, José Lages
In this article, we explore both numerically and analytically how the dynamical environments of mildly relativistic binaries evolve with increasing the general relativity factor $γ…
Massive evaluation and analysis of Poincaré recurrences on grids of initial data: a tool to map chaotic diffusion
Ivan I. Shevchenko, Guillaume Rollin, Alexander V. Melnikov +1
We present a novel numerical method aimed to characterize global behaviour, in particular chaotic diffusion, in dynamical systems. It is based on an analysis of the Poincaré recurr…
Contagion in Bitcoin networks
Célestin Coquidé, José Lages, Dima L. Shepelyansky
We construct the Google matrices of bitcoin transactions for all year quarters during the period of January 11, 2009 till April 10, 2013. During the last quarters the network size…
Interdependence of sectors of economic activities for world countries from the reduced Google matrix analysis of WTO data
Célestin Coquidé, José Lages, Dima L. Shepelyansky
We apply the recently developed reduced Google matrix algorithm for the analysis of the OECD-WTO world network of economic activities. This approach allows to determine interdepend…
Influence of petroleum and gas trade on EU economies from the reduced Google matrix analysis of UN COMTRADE data
Célestin Coquidé, Leonardo Ermann, José Lages +1
Using the United Nations COMTRADE database we apply the reduced Google matrix (REGOMAX) algorithm to analyze the multiproduct world trade in years 2004-2016. Our approach allows to…
