- 《Nature Electronics》 被引量: 4发表: 2018年 Robustness and mode selectivity in parity-time (PT) symmetric lasers We investigate two important aspects of PT symmetric photonic molecule lasers, namely the robustness of their single longitudinal mode operation against instabilities triggered by ...
Abstract Physicists are always riveted in predicting how a physical system behaves as a function of time. We begin this review article by understanding various formalisms to study the dynamics of the systems. The once-accepted belief that the Hamiltonian had to be Hermitian to ensure real eigenval...
In the configuration of symmetric triple microrings, each eigenmode has three peaks in the output spectrum due to localized and non-localized modes in three microrings7, and it is essential to use the broken PT-symmetry method for achieving the single-mode lasing. Due to the increase in the ...
The dynamics of an open quantum system with balanced gain and loss is not described by a PT-symmetric Hamiltonian but rather by Lindblad operators. Nevertheless the phenomenon of PT-symmetry breaking and the impact of exceptional points can be observed in the Lindbladean dynamics. Here we briefly...

They also found a mirror symmetric sublattices, which is similar to the puckered surface structure of black phosphorus [92]. Besides 2D islands, one-dimensional (1D) PdSe2 nanostructures form on top of the PdSe2 islands [91]. To understand the 1D PdSe2 nanostructures, Li et al. fabricated...
We also, consider the Hofstadter butterfly of a PT-symmetric one-dimensional system and show that by increasing the intensity of the potential imaginary part, we can kill the butterfly.doi:10.1007/s10825-020-01576-5M. SolaimaniSpringer USJournal of Computational Electronics...
