Dynamics of a system of coupled inverted pendula with vertical forcing
Nivedita Bhadra
Dynamical stabilization of an inverted pendulum through vertical movement of the pivot is a well-known counterintuitive phenomenon in classical mechanics. This system is also known…
Hamiltonian mean field model : effect of temporal perturbation in coupling matrix
Nivedita Bhadra, Soumen K Patra
The Hamiltonian mean-field (HMF) model is a system of fully coupled rotators which exhibits a second-order phase transition at some critical energy in its canonical ensemble. We in…
Dynamical systems analysis of phantom models
Nandan Roy, Nivedita Bhadra
In this work, we study the dynamical systems analysis of phantom dark energy models considering a general potential. The stability analysis of the system shows that there is only o…
Noise induced transition in Josephson junction with second harmonic
Nivedita Bhadra
We show a noise-induced transition in Josephson junction with fundamental as well as second harmonic. A periodically modulated multiplicative colored noise can stabilize an unstabl…
