Visibility graph analysis of solar wind velocity
Vinita Suyal, Awadhesh Prasad, Harinder P. Singh
We analyze in situ measurements of solar wind velocity obtained by Advanced Composition Explorer (ACE) spacecraft and Helios spacecraft during the years 1998-2012 and 1975-1983 res…
Amplitude Death: The cessation of oscillations in coupled nonlinear dynamical systems
Garima Saxena, Nirmal Punetha, Awadhesh Prasad +1
Here we extend a recent review (Physics Reports {\bf 521}, 205 (2012)) of amplitude death, namely the suppression of oscillations due to the coupling interactions between nonlinear…
Amplitude death phenomena in delay--coupled Hamiltonian systems
Garima Saxena, Awadhesh Prasad, Ram Ramaswamy
Hamiltonian systems, when coupled {\it via} time--delayed interactions, do not remain conservative. In the uncoupled system, the motion can typically be periodic, quasiperiodic or…
Driving--induced bistability in coupled chaotic attractors
Manish Agrawal, Awadhesh Prasad, Ram Ramaswamy
We examine the effects of symmetry--preserving and breaking interactions in a drive--response system where the response has an invariant symmetry in the absence of the drive. Subse…
Enhancement of photon intensity in forced coupled quantum wells inside a semiconductor microcavity
Hichem Eleuch, Awadhesh Prasad, Ingrid Rotter
We study numerically the photon emission from a semiconductor microcavity containing quantum wells under the influence of a periodic external forcing. The emission is dete…
