Topological Eigenvalue Braiding and Quantum State Transfer Near a Third-Order Exceptional Point

Non-Hermitian systems exhibit a variety of unique features rooted in the presence of exceptional points (EPs). The distinct topological structure in the proximity of an EP gives rise to counterintuitive behaviors absent in Hermitian systems, which emerge after encircling the EP either quasistaticall...
