Synchronization and partial synchronization of linear maps
Adam Lipowski, Michel Droz
We study synchronization of low-dimensional () chaotic piecewise linear maps. For Bernoulli maps we find Lyapunov exponents and locate the synchronization transition, that…
Extinction dynamics of Lotka-Volterra ecosystems on evolving networks
Francois Coppex, Michel Droz, Adam Lipowski
We study a model of a multi-species ecosystem described by Lotka-Volterra-like equations. Interactions among species form a network whose evolution is determined by the dynamics of…
Radial Velocity Studies of Close Binary Stars. IX
Wojtek Pych, Slavek M. Rucinski, Heide DeBond +8
Radial-velocity measurements and sine-curve fits to the orbital velocity variations are presented for the eighth set of ten close binary systems: AB And, V402 Aur, V445 Cep, V2082…
From dispersionless to soliton systems via Weyl-Moyal like deformations
Maciej Blaszak, Blazej Szablikowski
The formalism of quantization deformation is reviewed and the Weyl-Moyal like deformation is applied to systematic construction of the field and lattice integrable soliton systems…
Stationary two-atom entanglement induced by nonclassical two-photon correlations
R. Tanas, Z. Ficek
A system of two two-level atoms interacting with a squeezed vacuum field can exhibit stationary entanglement associated with nonclassical two-photon correlations characteristic of…
Superconductivity in a two-component model with local electron pairs
R. Micnas, S. Robaszkiewicz, A. Bussmann-Holder
Superconductivity in the two component model of coexisting local electron pairs (hard-core charged bosons) and itinerant fermions coupled via charge exchange mechanism is discussed…
