Reply to "Comment on `Winding around non-Hermitian singularities' by Zhong et al., Nat. Commun. 9, 4808 (2018)"
Q. Zhong, M. Khajavikhan, D. N. Christodoulides +1
A comment has been recently posted on the arXiv (arXiv:1902.07504) that discuss our recent work on encircling multiple exceptional points in Nat. Commun. 9, 4808 (2018). In that co…
Non-Hermitian engineering for brighter broadband pseudothermal light
Nicolás Quesada, Eugene Adjei, Ramy El-Ganainy +1
We show that non-Hermitian engineering can play a positive role in quantum systems. This is in contrast to the widely accepted notion that optical losses are a foe that must be eli…
Winding around Non-Hermitian Singularities: General Theory and Topological Features
Qi Zhong, Mercedeh Khajavikhan, Demetrios Christodoulides +1
Non-Hermitian singularities are ubiquitous in non-conservative open systems. These singularities are often points of measure zero in the eigenspectrum of the system which make them…
Localization control of few-photon states in parity-symmetric photonic molecules under balanced pumping
C D B Bentley, A Celestino, A M Yacomotti +2
We theoretically investigate the problem of localization control of few-photon states in driven-dissipative parity-symmetric photonic molecules. We show that a quantum feedback loo…
Non-Hermitian matter wave mixing in Bose Einstein condensates: dissipation induced amplification
S. Wüster, R. El-Ganainy
We investigate the nonlinear scattering dynamics in interacting atomic Bose-Einstein condensates under non-Hermitian dissipative conditions. We show that by carefully engineering a…
Computation of spontaneous emission dynamics in colored vacua
Mohammad Hosain Teimourpour, Ramy El-Ganainy
We present an efficient time domain numerical scheme for computing spontaneous emission dynamics in colored vacua. Starting from first principles, we map the unitary evolution of a…
