Strongly correlated states of light and repulsive photons in chiral chains of three-level quantum emitters

OA Iversen, T Pohl - Physical Review Letters, 2021 - APS
We study the correlated transport of photons through a chain of three-level emitters that are
coupled chirally to a photonic mode of a waveguide. It is found that this system can transfer a …

Phase-space methods for simulating the dissipative many-body dynamics of collective spin systems

Self-ordering of individual photons in waveguide QED and Rydberg-atom arrays

OA Iversen, T Pohl - Physical Review Research, 2022 - APS
The scattering between light and individual saturable quantum emitters can induce strong
optical nonlinearities and correlations between individual light quanta. Typically, this leads …
