"Dynamically Manipulating Topological Physics and Edge Modes in a Single Degenerate Optical Cavity." <i>Physical Review Letters,</i> 118, no. 8 (2017) American Physical Society: https://doi.org/10.1103/PhysRevLett.118.083603.https://hdl.handle.net/1911/94118We propose a scheme to simulate topological physics within a single degenerate cavity, whose modes are mapped to lattice sites. A crucial ingredient of the scheme is to construct a sharp boundary so that the open boundary condition can be implemented for this effective lattice system. In doing so, the topological properties of the system can manifest themselves on the edge states, which can be probed from the spectrum of an output cavity field. We demonstrate this with two examples: a static Su-Schrieffer-Heeger chain and a periodically driven Floquet topological insulator. Our work opens up new avenues to explore exotic photonic topological phases inside a single optical cavity.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
