	   Fractal Characteristics of Wave-Functions in 
		Systems with Competing Periodicities

			Indubala Satija
	Department of Physics, George Mason University

	Systems with two irrationaly related frequencies have been
of great interest in the interdisciplinary field of Condensed Matter
and Nonlinear Dynamics. The exotic behavior of these systems have
attracted experimentalists, theoreticians as well as mathematicians
for last two decades. These systems are inbetween periodic and random
systems and exhibit phase transition in one dimension. In this talk
I will review properties of such systems and describe some of my
very recent results. This will include " Self-Similarity and
Localization" in two-dimensional electron gas and " Devil-Staircase
Phonons" in Frankel-Konterova model. The later problem is related
to the famous standard area-preserving map in the theory of
non-integrable Hamiltonian systems.
