Superradiant decay in non-Markovian Waveguide Quantum Electrodynamics
Rosa Lucia Capurso, Giuseppe Calajó, Simone Montangero +5
An array of initially excited emitters coupled to a one-dimensional waveguide exhibits superradiant decay under the Born-Markov approximation, manifested as a coherent burst of pho…

Squeezing Classical Antiferromagnets into Quantum Spin Liquids via Global Cavity Fluctuations
Charlie-Ray Mann, Mark A. Oehlgrien, Błażej Jaworowski +4
Cavity quantum electrodynamics with atomic ensembles is typically associated with collective spin phenomena, such as superradiance and spin squeezing, in which the atoms evolve col…

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…
