Weyl points and exceptional rings with polaritons in bulk semiconductors
R. L. Mc Guinness, P. R. Eastham
Weyl points are the simplest topologically-protected degeneracy in a three-dimensional dispersion relation. The realization of Weyl semimetals in photonic crystals has allowed thes…
Chern numbers for the index surfaces of photonic crystals: conical refraction as a basis for topological materials
R. L. Mc Guinness, P. R. Eastham
The classification of bandstructures by topological invariants provides a powerful tool for understanding phenomena such as the quantum Hall effect. This classification was origina…
Adiabatic state preparation of interacting two-level systems
R. T. Brierley, C. Creatore, P. B. Littlewood +1
We consider performing adiabatic rapid passage (ARP) using frequency-swept driving pulses to excite a collection of interacting two-level systems. Such a model arises in a wide ran…
Amplitude-mode dynamics of polariton condensates
R. T. Brierley, P. B. Littlewood, P. R. Eastham
We study the stability of collective amplitude excitations in non-equilibrium polariton condensates. These excitations correspond to renormalized upper polaritons and to the collec…
Microcavity quantum-dot systems for non-equilibrium Bose-Einstein condensation
I. M. Piper, P. R. Eastham, M. Ediger +5
We review the practical conditions required to achieve a non-equilibrium BEC driven by quantum dynamics in a system comprising a microcavity field mode and a distribution of locali…
Bose condensation in a model microcavity
P. R. Eastham, P. B. Littlewood
We study the equilibrium properties of a system of dipole-active excitons coupled to a single photon mode at fixed total excitation. Treating the presence or absence of a trapped e…
