# Many-body superradiance and dynamical symmetry breaking in waveguide QED

@inproceedings{CardenasLopez2022ManybodySA, title={Many-body superradiance and dynamical symmetry breaking in waveguide QED}, author={Silvia Cardenas-Lopez and Stuart J Masson and Zoe Zager and Ana Asenjo-Garcia}, year={2022} }

The many-body decay of extended collections of two-level systems remains an open problem. Here, we investigate whether an array of qubits coupled to a one-dimensional bath undergoes Dicke superradiance, a process whereby a completely inverted system synchronizes as it decays, generating correlations between qubits via dissipation. This leads to the release of all the energy in the form of a rapid photon burst. We derive the minimal conditions for the burst to happen as a function of the number…

It is shown that the superradiant burst survives at small distances, despite Hamiltonian dipole-dipole interactions, and the two-photon correlation function is calculated and demonstrated that emission is correlated and directional, as well as sensitive to small changes in the interatomic distance.
