“Topological lasers and condensates”

Topological photonics aims to replicate fermionic symmetries as feats of precision engineering. I describe how to enhance these systems via effects such as gain, loss and nonlinearities that do not have a direct electronic counterpart. This leads to a topological mechanism of mode selection useful for lasers, formation of compactons in flat band condensates, as well as topological excitations. The resulting effects show a remarkable practical robustness against disorder, which arises from the increased spectral isolation of the manipulated states.
