Chiral transmission by an open evolution trajectory in a non-Hermitian system

In non-Hermitian systems, two or more eigenvalues and eigenstates of a resonant system coalesce at Exceptional points (EPs). Dynamic encircling of EPs has received significant interest in recent years, as it leads to highly nontrivial phenomena, such as chiral transmission, in which the final state of the system depends on the encircling handedness.
