Title: The phenomenon of amplitude death in coupled nonlinear systems

Speaker: Dr. Awadesh Prasad, Dept. of Physics & Astrophysics, University of Delhi, Delhi

Abstract: Natural systems are rarely isolated, and hence the interaction between such systems have been extensively studied from both theoretical and experimental points of view in a variety of contexts in the physical, biological, and social sciences. Several interesting new phenomena arise in such interacting systems. Amplitude death (AD) is an important phenomenon that can also occur in coupled nonlinear oscillators when their interaction causes the fixed points to become stable and attracting. In this talk we will review the various routes to AD as well general situations under which AD occurs. We will also discuss the possibility of AD in Hamiltonian and Non-Hamiltonian systems, as well as systems having normal and hidden attractors. The different control methods using AD will be also discussed.
