encircling the exceptional point (EP) in a PT symmetric system for asymmetric mode switching has caught people’s eyes because of its potential in the design of chiral devices. In photonic systems, the dynamical variation o...

We report on the formation and stability of induced solitons in parity-time (PT) symmetric periodic systems with the logarithmically saturable nonlinearity. Both on-site and off-site lattice solitons exist for the self-focusing nonlinearity. The most intriguing result is that the above solitons can...

都有很深的造诣,我们其实早就介绍过Fleury教授的工作,如声学非互易- 2014 Science 基于环形气流的声隔离,他在回瑞士的EPFL之后,已经作为PI发了很多牛逼文章,我们今天想介绍的,是他2018年发表在PRA上的一篇理论文章,标题是Parametric amplification and bidirectional invisibility in PT-symmetric time-Floquet systems。
