Geometric phase around exceptional points – arXiv Vanity
WebSep 1, 2016 · Particularly intriguing behaviour is predicted to appear when an exceptional point is encircled sufficiently slowly, such as a state-flip or the accumulation of a geometric phase. The topological structure of exceptional points has been experimentally explored, but a full dynamical encircling of such a point and the associated breakdown of ...

Geometric Phase - an overview ScienceDirect Topics
WebThe exceptional point is a new type of singular point of the Hamiltonian, which speci cally appears in non-Hermitian systems. The geometric phase around the exceptional points recently has great interest [10{15]. For Hermitian systems, previous studies indicate that the origin of the geometric phase is the diabolic points, another singular point in Webclose to exceptional points. For more details on perturbation theory around exceptional points, see, e.g., [57] and the references cited therein. As indicated above, at an exceptional point, two or more eigenvalues and the corresponding eigenstates coalesce, that is, the Hamiltonian is not diagonalisable. WebJan 4, 2024 · In integrated photonic platforms, exceptional points and phase transitions have been observed in coupled passive optical waveguides, where controllable loss in one of the ...
