The recent paper published on March 5, 2020 in Physical Review Letters [J. Zhong et al, Phys. Rev Lett.124, 093604 (2020)] is largely based on the results of the Honours thesis of Ms. Janet Zhong (currently a new PhD student of the School).
This paper opens a new direction in the physics of quantum many-body systems by predicting a novel type of interaction-induced spatial localization in a qubit arrays coupled to a waveguide. This localization can be described as a quantum analogue of a self-induced optical lattice between two indistinguishable photons, where one photon creates a standing wave that traps the other photon.
