Non-Hermitian optical dimers coupled to superfluids enable topological sensing of superfluid winding numbers via exceptional-point eigenmode permutations in optical transmission.
Focusing now on the passive cavity, it is driven by two coherent control tones at frequenciesω L1 andω L2 with complex drive strengthsε 1 andε 2
