Island-dynamics model for mound formation:Effect of a step-edge barrier
Island-dynamics model mound formation step-edge barrier
2015/10/16
We formulate and implement a generalized island-dynamics model of epitaxial growth based on the level-set technique to include the effect of an additional energy barrier for the attachment and detachm...

By varying the parameters c and δ we obtain bifurcation curves which divide the cδ-plane into more than forty regions,each containing a distinct slow flow. Individual regions are found to differ from ...
In 2006, the fourth author of this paper proposed a graph-theoretic model of interface dynamics called competitive erosion. Each vertex of the graph is occupied by a particle that can be either red or...
A SIMPLE MODEL FOR ASSET PRICE BUBBLE FORMATION AND COLLAPSE
ASSET PRICE BUBBLE FORMATION COLLAPSE
2015/7/14
We consider a simple stochastic differential equation for modeling bubbles in social context. A prime example is bubbles in asset pricing, but similar mechanisms may control a range of social phenomen...
Opto-Mechanical Pattern Formation in Cold Atoms
Opto-Mechanical Pattern Formation Cold Atoms Pattern Formation and Solitons
2012/4/27
Transverse pattern formation in an optical cavity containing a cloud of cold two-level atoms is discussed. We show that density modulation becomes the dominant mechanism as the atomic temperature is r...
