Wake-induced dynamics of soft-impact oscillators: Analysis and electronic experimental validation
Rohit Chawla, Soumyajit Seth, Vikram Pakrashi
This article presents an electronic experimental validation of discontinuity-induced bifurcations, including period-adding cascades, in a wake-induced dynamical system subjected to…
Higher-Order Transverse Discontinuity Mapping in Filippov Systems: Analysis and Experimental Validation using an Electronic Circuit
Rohit Chawla, Soumyajit Seth, Aasifa Rounak +1
This paper shows that linearizing the transverse discontinuity mapping (TDM) in Filippov systems can produce inaccurate predictions of the dynamics in impact oscillators operating…
Wake-induced response of vibro-impacting systems
Rohit Chawla, Aasifa Rounak, Chandan Bose +1
The stability and bifurcation behaviour of a wake-induced vibro-impacting oscillator is studied. The effects of a discontinuity on the stability of the structure while it is underg…
Improved Stability Estimates and Flight Time Predictions Using Higher-Order Transverse Discontinuity Mapping in Hybrid Dynamical Systems
Rohit Chawla, Aasifa Rounak, Vikram Pakrashi
This article emphasizes on inconsistencies in the dynamical estimates obtained by first-order transverse discontinuity mapping (TDM) and direct numerical observations for hybrid dy…
Quantum fluctuations stabilize an inverted pendulum
Rohit Chawla, Soumyabrata Paul, Jayanta K. Bhattacharjee
We explore analytically the quantum dynamics of a point mass pendulum using the Heisenberg equation of motion. Choosing as variables the mean position of the pendulum, a suitably d…
