Evidence for dynamical changes in Betelgeuse using multi-wavelength data
Sneha Kachhara, Sandip V. George, Ranjeev Misra +1
The reasons behind the Great Dimming and subsequent rising in the brightness of Betelgeuse between October 2019 and March 2020 still continue to baffle astronomers. It has been sho…
Emergent Dynamics and Spatio Temporal Patterns on Multiplex Neuronal Networks
Umesh Kumar Verma, G. Ambika
We present a study on the emergence of a variety of spatio temporal patterns among neurons that are connected in a multiplex framework, with neurons on two layers with different fu…
Early warning signals for critical transitions in complex systems
Sandip V. George, Sneha Kachhara, G. Ambika
In this topical review, we present a brief overview of the different methods and measures to detect the occurrence of critical transitions in complex systems. We start by introduci…
Frequency chimera state induced by differing dynamical timescales
Sneha Kachhara, G. Ambika
We report the occurrence of a self-emerging frequency chimera state in spatially extended systems of coupled oscillators, where the coherence and incoherence are defined with respe…
Tipping induced by multiplexing on two layer networks
Umesh Kumar Verma, G. Ambika
We report the study of sudden transitions or tipping in a collection of systems induced due to multiplexing with another network of systems. The emergent dynamics of oscillators on…
Frequency locking, Quasi periodicity and Chaos due to special relativistic effects
Derek C. Gomes, G. Ambika
We study quasi periodic and frequency locked states that can occur in a sinusoidally driven linear harmonic oscillator in the special relativistic regime. We show how the shift in…
