Effect of interlayer exchange coupling in spin-torque nano oscillator
R. Arun, R. Gopal, V. K. Chandrasekar +1
The dynamics of the magnetization of the free layer in a spin-torque nano oscillator (STNO) influenced by a noncollinear alignment between the magnetizations of the free and pinned…
Inhomogeneous nonlinearity meets -symmetric Bragg structures: Route to ultra-low power steering and peculiar stable states
S. Sudhakar, S. Vignesh Raja, A. Govindarajan +2
In the context of -symmetric fiber Bragg gratings, tailoring the nonlinear profile along the propagation coordinate serves to be a new direction for realizing low-pow…
Bright, dark and breather soliton solutions of the generalized long-wave short-wave resonance interaction system
M. Kirane, S. Stalin, M. Lakshmanan
In this paper, a generalized long-wave short-wave resonance interaction system, which describes the nonlinear interaction between a short-wave and a long-wave in fluid dynamics, pl…
Stabilization of light bullets in nonlinear metamaterial waveguides
A. K. Shafeeque Ali, A. Govindarajan, M. Lakshmanan
In this paper, we carry out a theoretical investigation on the propagation of spatio-temporal solitons (light bullets) in the nonlinear metamaterial waveguides. Our theoretical stu…
Thermal quantum correlations and teleportation under PT-symmetric system
J. Ramya Parkavi, R. Muthuganesan, V. K. Chandrasekar +1
In this article, we exploit the different notions of quantumness measure to understand the properties of the Heisenberg XY model with and without PT-symmetric operation. In the abs…
Low-power optical bistability in -symmetric chirped Bragg gratings with four-wave mixing
S. Sudhakar, S. Vignesh Raja, A. Govindarajan +2
The central theme of this article is the analysis of the usefulness of introducing four-wave mixing or modulation of Kerr nonlinearity in a nonuniform grating structure with gain a…
