Bifurcations of a Van der Pol oscillator in a double well
Satadal Datta
We study the changes in the phase portrait of a Van der Pol oscillator in a double well with the change in the shape of the well. Both the symmetric and asymmetric double wells are…
Amplitude death by delay induced position coupling in a system of two coupled Van der Pol Oscillators
Satadal Datta
We consider a system of two interacting identical Van der Pol Oscillators in a simple harmonic potential well. The position coupling term between the oscillators is such that there…
Analogue tachyon in Jeans Cloud
Satadal Datta
We study the linear perturbations in a stable Jeans cloud, i.e; the dimension of the cloud is less than the Jeans length. We find that the linear perturbation of density in such a…
A parametric model to study the mass radius relationship of stars
Safiqul Islam, Satadal Datta, Tapas K Das
In static and spherically symmetric spacetime, we solve the Einstein Maxwell equations. The effective gravitational potential and the electric field for charged anisotropic fluid a…
