CP_N Solitons in Quantum Hall Systems
R. Rajaraman
We will present here an elementary pedagogical introduction to solitons in quantum Hall systems. We begin with a brief introduction to both models and to quantum Hall…
Structural and electronic properties of the Nb-cluster compound GaNbX (X = S, Se)
Asad Niazi, A. K. Rastogi
We report resistivity, thermopower and magnetic susceptibility measurements on the Nb-cluster compounds GaNbX (X = S, Se), derived from vacancy ordered spine…
White Hole, Black Whole, and The Book
Kannan Nambiar
Intellectual space is defined as the set of all proofs of mathematical logic, contained in The Book conceived by Erdos. Physical and intellectual spaces are visualized, making use…
Low temperature resistance minimum in non-superconducting 3R-Nb_{1+x}S_2 and 3R-Ga_xNbS_2
Asad Niazi, A. K. Rastogi
We report the structural and electron transport properties of 3R-Nb_{1+x}S_2 (x >= .07) and 3R-Ga_xNbS_2 (.1 <= x <= .33) prepared as polycrystalline pellets as well as single crys…
Strange Nonchaotic Attractors
Awadhesh Prasad, Surendra Singh Negi, Ramakrishna Ramaswamy
Aperiodic dynamics which is nonchaotic is realized on Strange Nonchaotic attractors (SNAs). Such attractors are generic in quasiperiodically driven nonlinear systems, and like stra…
Bifurcations and transitions in the quasiperiodically driven logistic map
Surendra Singh Negi, Awadhesh Prasad, Ramakrishna Ramaswamy
We discuss several bifurcation phenomena that occur in the quasiperiodically driven logistic map. This system can have strange nonchaotic attractors (SNAs) in addition to chaotic a…
