Title: Observation of Floquet-engineered non-Hermitian topology with single photons

Abstract: The non-Hermitian topology leads to the emergence of various counter-intuitive phenomena, which can not find a counterpart in Hermitian systems. In this talk, we will discuss our recent experimental realization of various Floquet-engineered non-Hermitian topological states in the non-unitary dynamics of single photons [1-3]. Our work would provide a useful platform to study the non-equilibrium non-Hermitian topology
