Quantized Orbits and Resonant Transport
Indubala I. Satija, Bala Sundaram
A tight binding representation of the kicked Harper model is used to obtain an integrable semiclassical Hamiltonian consisting of degenerate "quantized" orbits. New orbits appear w…
Collision and symmetry-breaking in the transition to strange nonchaotic attractors
Awadhesh Prasad, Ramakrishna Ramaswamy, Indubala I. Satija +1
Strange nonchaotic attractors (SNAs) can be created due to the collision of an invariant curve with itself. This novel ``homoclinic'' transition to SNAs occurs in quasiperiodically…
Breakup of a Dimer: a New Approach to Localization Transition
Ignacio Gomez, Indubala I. Satija
Within the framework of tight binding models, aperiodic systems are mapped to a renormalized lattice with a dimer defect. In models exhibiting metal-insulator transition, the dimer…
Dimer-Type Correlations and Band Crossings in Fibonacci Lattices
Ignacio G. Cuesta, Indubala I. Satija
Fibonacci system with both diagonal and off-diagonal disorder is mapped to a model with dimer type 'defects'. The model exhibit resonance transition corresponding to zero reflectan…
Localization and Fluctuations in Quantum Kicked Rotors
Indubala I. Satija, Bala Sundaram, Jukka A. Ketoja
We address the issue of fluctuations, about an exponential lineshape, in a pair of one-dimensional kicked quantum systems exhibiting dynamical localization. An exact renormalizatio…
