Interfacial mixing in heteroepitaxial growth
Boris Bierwald, Michael von den Driesch, Zeno Farkas +2
We investigate the growth of a film of some element B on a substrate made of another substrance A in a model of molecular beam epitaxy. A vertical exchange mechanism allows the A-a…
Interplay of linear and modified nonlinear impurities in the formation of stationary localized states
Bikash C. Gupta, Sang Bub Lee
Formation of stationary localized states in one-dimensional chain due to a linear impurity and a modified nonlinear impurity is studied. Furthermore, a one-dimensional chain with l…
Self-trapping transition for nonlinear impurities embedded in a Cayley tree
Bikash C. Gupta, Sang Bub Lee
The self-trapping transition due to a single and a dimer nonlinear impurity embedded in a Cayley tree is studied. In particular, the effect of a perfectly nonlinear Cayley tree is…
Interplay of linear and nonlinear impurities in the formation of stationary localized states
Bikash C. Gupta, Sang Bub Lee
Formation of stationary localized states in one-dimensional chain as well as in a Cayley tree due to a linear impurity and a nonlinear impurity is studied. Furthermore, a one-dimen…
New way to achieve chaotic synchronization in spatially extended systems
Bikash Chandra Gupta, P. A. Sreeram, S. B. Lee
We study the spatio-temporal behavior of simple coupled map lattices with periodic boundary conditions. The local dynamics is governed by two maps, namely, the sine circle map and…
Stationary localized states due to nonlinear impurities described by the modified discrete nonlinear Schrödinger equation
Bikash C. Gupta, Sang Bub Lee
The modified discrete nonlinear Schrödinger equation is used to study the formation of stationary localized states in a one-dimensional lattice with a single impurity and an asymme…
