Strange Nonchaotic Attractors in the Quasiperiodically forced Logistic Map
Awadhesh Prasad, Vishal Mehra, Ramakrishna Ramaswamy
Different mechanisms for the creation of strange non-chaotic dynamics in the quasiperiodically forced logistic map are studied. These routes to strange nonchaos are characterised t…
Intermittency Route to Strange Nonchaotic Attractors
Awadhesh Prasad, Vishal Mehra, Ramakrishna Ramaswamy
Strange nonchaotic attractors (SNA) arise in quasiperiodically driven systems in the neighborhood of a saddle node bifurcation whereby a strange attractor is replaced by a periodic…
Curvature fluctuations and Lyapunov exponent at Melting
Vishal Mehra, Ramakrishna Ramaswamy
We calculate the maximal Lyapunov exponent in constant-energy molecular dynamics simulations at the melting transition for finite clusters of 6 to 13 particles (model rare-gas and…
