Multifaceted nonlinear dynamics in -symmetric coupled Liénard oscillators
Jyoti Prasad Deka, Arjunan Govindarajan, Manas Kulkarni +1
We propose a generalized parity-time () -symmetric Liénard oscillator with two different orders of nonlinear position-dependent dissipation. We study the stability of…
Non-Hermitian Optics
Amarendra K. Sarma
Non-Hermitian optics, mostly known as 'Parity-time symmetric optics', is considered as one of the frontiers areas of research in optical sciences at present. This area is largely i…
Tailoring -symmetric soliton switch
A. Govindarajan, Amarendra K. Sarma, M. Lakshmanan
We theoretically demonstrate soliton steering in -symmetric coupled nonlinear dimers. We show that if the length of the -symmetric system is set to …
Unconventional photon blockade in three-mode optomechanics
Bijita Sarma, Amarendra K. Sarma
We analyze the photon correlations in an optomechanical system containing two nonlinear optical modes and one mechanical mode which are coupled via a three-mode mixing. Under a wea…
Tunable phonon blockade in weakly nonlinear coupled mechanical resonators via Coulomb interaction
Bijita Sarma, Amarendra K. Sarma
Realizing quantum mechanical behavior in micro- and nanomechanical resonators has attracted continuous research effort. One of the ways for observing quantum nature of mechanical o…
Chaotic Dynamics and Optical Power Saturation in Parity-Time (PT) Symmetric Double Ring Resonator
Jyoti Prasad Deka, Amarendra K. Sarma
We report emergence of saturation and chaotic spiking of optical power in a double ring resonator with balanced loss and gain, obeying the so-called parity-time symmetry. We have m…
