Classification of three-photon states in waveguide quantum electrodynamics
Janet Zhong, Alexander N. Poddubny
We provide the first classification of three-photon eigenstates in a finite periodic array of two-level atoms coupled to a waveguide. We focus on the strongly subwavelength limit a…
Quantum chaos driven by long-range waveguide-mediated interactions
Alexander V. Poshakinskiy, Janet Zhong, Alexander N. Poddubny
We study theoretically quantum states of a pair of photons interacting with a finite periodic array of two-level atoms in a waveguide. Our calculation reveals two-polariton eigenst…
Quantum Hall phase emerging in an array of atoms interacting with photons
Alexander V. Poshakinskiy, Janet Zhong, Yongguan Ke +4
Topological quantum phases underpin many concepts of modern physics. While the existence of disorder-immune topological edge states of electrons usually requires magnetic fields, d…
Radiative topological biphoton states in modulated qubit arrays
Yongguan Ke, Janet Zhong, Alexander V. Poshakinskiy +3
We study topological properties of bound pairs of photons in spatially-modulated qubit arrays (arrays of two-level atoms) coupled to a waveguide. While bound pairs behave like Bloc…
