Dynamically Encircling Exceptional Points: In situ Control of Encircling Loops and the Role of the Starting Point

The most intriguing properties of non-Hermitian systems are found near the exceptional points (EPs) at which the Hamiltonian matrix becomes defective. Because of the complex topological structure of the energy Riemann surfaces close to an EP and the breakdown of the adiabatic theorem due to non-Herm...
