Quantum Fisher information and skew information correlations in dipolar spin system
R. Muthuganesan, V. K. Chandrasekar
Quantum Fisher information (QFI) and skew information (SI) plays a key role in the quantum resource theory. Understanding these measures in the physical system has practical signif…
Influence of dissipation on extreme oscillations of a forced anharmonic oscillator
B. Kaviya, R. Suresh, V. K. Chandrasekar +1
Dynamics of a periodically forced anharmonic oscillator (AO) with cubic nonlinearity, linear damping, and nonlinear damping, is studied. To begin with, the authors examine the dyna…
Parametric excitation induced extreme events in MEMS and Lienard oscillator
R. Suresh, V. K. Chandrasekar
The two paradigmatic nonlinear oscillatory models with parametric excitation are studied. The authors provide theoretical evidence for the appearance of extreme events (EEs) in tho…
The Kuramoto model in presence of additional interactions that break rotational symmetry
V K Chandrasekar, M Manoranjani, Shamik Gupta
The Kuramoto model serves as a paradigm to study the phenomenon of spontaneous collective synchronization. We study here a nontrivial generalization of the Kuramoto model by includ…
Intrinsic decoherence effects on measurement-induced nonlocality
R. Muthuganesan, V. K. Chandrasekar
By considering an exactly solvable model of a two interacting spin-1/2 qubits described by the Heisenberg anisotropic interaction in the presence of intrinsic decoherence, we study…
Dynamical modelling and analysis of COVID-19 in India
R. Gopal, V. K. Chandrasekar, M. Lakshmanan
We consider the pandemic spreading of COVID-19 in India after the outbreak of the coronavirus in Wuhan city, China. We estimate the transmission rate of the initial infecting indiv…
