Multi-level quantum emitter in an optical waveguide: paradoxes and resolutions
Ben Lang
We theoretically investigate the optical dipole interaction between a multi-level quantum system and a single-mode optical waveguide of any local polarisation. We investigate sever…

Local-photon model of the momentum of light
Gabriel Waite, Daniel Hodgson, Ben Lang +2
Recently we introduced a local photon approach for modelling the quantised electromagnetic field in position space. Using this approach, we define the momentum of light in this pap…

Multipartite entanglement in a Josephson Junction Laser
Ben Lang, Andrew D. Armour
We analyse the entanglement in a model Josephson photonics system in which a dc voltage-biased Josephson junction couples a collection of cavity modes and populates them with micro…
