讲座内容：

In contrast to a Hermitian system, in which zero modes are usually a degenerate and localized edge state in the thermodynamic limit, the zero mode of a finite non-Hermitian system can be a single nontrivial long-rangeentangled state at the exceptional point. In this work, we demonstrate this feature with a concrete example based on exact solutions. Numerical simulations show that the entangled state can be generated through the dynamic process with a high fidelity.
