Photonic topological Lifshitz interfaces.

ABSTRACT: The intrinsic geometry of wavevector diagrams describes electronic or photonic transport at a given energy level. Lifshitz transition is an intriguing example of the topological transition in wavevector diagrams, which plays a critical role in abnormal transport with enhanced magnetoresistance or superconductivity. Here, we develop the spatial analogy of the Lifshitz transition, which provides a comprehensive topological perspective on transverse-spin interface states. We establish the excitation conditions of transverse-spin interface states, which require the "Lifshitz interface" - the interface between different topologies of wavevector diagrams - along with the gap in wavevector diagrams. Based on the detailed analysis of this topological phenomenon with respect to the dimensionality a
