Delay regulated explosive synchronization in multiplex networks

AD Kachhvah, S Jalan - New Journal of Physics, 2019 - iopscience.iop.org
It is known that explosive synchronization (ES) in an isolated network of Kuramoto oscillators
with inertia is significantly enhanced by the presence of time delay. Here we show that time …
