Intrinsic geometry approach to surface kinetic roughening

Universality issues in surface kinetic roughening of thin solid films

Since publication of the main contributions on the theory of kinetic roughening more than fifteen years ago, many works have been reported on surface growth or erosion that employ the framework of dynamic scaling. This interest was mainly due to the predicted existence of just a few universality classes to describe the statistical properties of the morphology of growing surfaces and interfaces ...

Kinetic Surface Roughening and Pattern Formation in Molecular Beam Epitaxy

Nonlocality in Kinetic Roughening

“Suppose that we take a bin and gently and uniformly pour in granular material. As the material in the bin builds up we can identify a surface and ask the question, ‘What is the magnitude of the fluctuation in the height of surface (measured from the base of the bin)?’ Also of interest is the length scale of the surface fluctuations and how they behave dynamically as more material is added” [1]...

The Variable Geometry Approach to International

Negotiations among nations on policies to promote international economic integration have widened in recent years to cover new issues; for example, foreign direct investment rules, policies to promote competition, the international movement of labor, the environment and monetary union. In these negotiations, a consensus among the parties negotiating is usually lacking and many of these negotiat...

From Surface Roughening to Qcd String Theory

There exists great interest and considerable effort to explain quark confinement in Quantum Chromodynamics (QCD) from the string theory viewpoint. The ideas of ’t Hooft, Polyakov, Witten, and others, and recent glueball spectrum or QCD string tension calculations in AdS theories are some illustrative examples of these activities. In a somewhat complementary approach, the search for a microscopi...
