Bound States in the Continuum in Bilayer Photonic Crystal with TE-TM Cross-Coupling
Hong-Fei Wang, Samit Kumar Gupta, Xue-Yi Zhu +3
Bound states in the continuum (BICs) in photonic crystals represent the unique solutions of wave equations possessing an infinite quality-factor. We design a type of bilayer photon…

Peregrine rogue waves in the nonlocal nonlinear Schrödinger equation with parity-time symmetric self-induced potential
Samit Kumar Gupta
In this work, based on the recently proposed (Phys. Rev. Lett. 110 (2013) 064105) continuous nonlocal nonlinear Schrödinger system with parity-time symmetric Kerr nonlinearity (PTN…
