Phase transition in urban agglomeration and segregation
Taksu Cheon, Michikazu Kobayashi
A model of the urban agglomeration and segregation is formulated, in which two types of agents move around on the square-lattice aligned cells. The model is shown to exhibit, when…
Current production in ring condensates with a weak link
Axel Pérez-Obiol, Juan Polo, Taksu Cheon
We consider attractive and repulsive condensates in a ring trap stirred by a weak link, and analyze the spectrum of solitonic trains dragged by the link, by means of analytical exp…
Asymmetric contrarians in opinion dynamics
Serge Galam, Taksu Cheon
Asymmetry in contrarian behavior is investigated within the Galam model of opinion dynamics using update groups of size 3 with two competing opinions A and B. Denoting and …
Generating nonequilibrium stationary state from ground state condensate through an almost-adiabatic cycle
Atushi Tanaka, Takaaki Nakamura, Taksu Cheon
It is shown that the ground state of weakly interacting Bose particles in a quasi one-dimensional box trap can be converted into an excited stationary state by an adiabatic cyclic…
One dimensional Hydrogen problem with general connection condition at the origin and non-Rydberg spectra
Axel Pérez-Obiol, Taksu Cheon
We consider the solution of the quantum Coulomb problem in one dimension with the most general connection condition at the origin. The divergence of the derivative of the wave func…
Bose-Einstein condensate confined in a 1D ring stirred with a rotating delta link
Axel Pérez-Obiol, Taksu Cheon
We consider a Bose-Einstein condensate with repulsive interactions confined in a 1D ring where a Dirac delta is rotating at constant speed. The spectrum of stationary solutions in…
