Study of Duffing oscillator using an improved Lindstedt Poincare method and relevant comparisons
Ramij Ahamed, Subhankar Ray
The undamped Duffing oscillator is a nonlinear dynamical system with broad applications in physics, engineering and biological system. We present a comprehensive analysis of this s…
Feature-rich bifurcations in a simple electronic circuit
Debdipta Goswami, Subhankar Ray
A simple electronic circuit with a voltage controlled current source is investigated. The circuit exhibits rich dynamics upon varying the circuit elements such as L,C and R, and th…
Generalized ballistic deposition in 2 dimensions : scaling of surface width, porosity and conductivity
Subhankar Ray, Baisakhi Mal, J. Shamanna
A deposition process with particles having realistic intermediate stickiness is studied in 2+1 dimensions. At each stage of the deposition process, for any given configuration, a n…
Surface properties and scaling behavior of a generalized ballistic deposition model in (1+1)-dimension
Baisakhi Mal, Subhankar Ray, J. Shamanna
The surface exponents, the scaling behavior and the bulk porosity of a generalized ballistic deposition (GBD) model are studied. In nature, there exist particles with varying degre…
Surface morphology of a modified ballistic deposition model
Kasturi Banerjee, J. Shamanna, Subhankar Ray
The surface and bulk properties of a modified ballistic deposition model are investigated. The deposition rule interpolates between nearest and next-nearest neighbor ballistic depo…
Damped bead on a rotating circular hoop - a bifurcation zoo
Shovan Dutta, Subhankar Ray
The evergreen problem of a bead on a rotating hoop shows a multitude of bifurcations when the bead moves with friction. This motion is studied for different values of the damping c…
