Non-Hermitian synthetic lattices with light-matter coupling
Non-Hermitian synthetic lattices with light-matter coupling
We propose that light-matter coupling can be used to realize synthetic lattices. In particular, we consider a one-dimensional chain of exciton-photon sites to create a comb lattice that exhibits a transition from a flat band to a finite mass dispersion by tuning site-dependent light-matter coupling. Moreover, in a non-Hermitian system …
