Flat band mediated photon-photon interactions in 2D waveguide QED networks
Matija Tečer, Giuseppe Calajó, Marco Di Liberto
We investigate a Lieb lattice of quantum emitters coupled to a two-dimensional waveguide network and demonstrate that this system supports an energetically isolated flat band, enab…

Many-body quantum dimerization in 2D atomic arrays
Giuseppe Calajò, Matija Tečer, Simone Montangero +2
We consider a 2D atomic array coupled to different photonic environments, focusing on the half-filled excitation subspace, where strong photon interactions can give rise to complex…
