Controllable half-vortex lattices in an incoherently pumped polariton condensate

, 2011
We show how the transition between synchronized and desynchronized states of a spinor polariton condensate can be used to drive a transition between stationary vortex lattices and half-vortex lattices. This provides a way to control polariton spin textures by a combination of pump spot profile and applied magnetic fields.

Steady state engineering of a two-level system by the mixed-state inverse engineering scheme

Scientific Reports
The mixed-state inverse engineering scheme is a control scheme used for engineering the quantum state of a driven open quantum system from an initial steady state to a final steady state.

Academies, autonomy, equality and democratic accountability: Reforming the fragmented publicly funded school system in England

London Review of Education, 2019
This article focuses on the transformative academies policy in England. Based on an analysis of documentary evidence, we argue that the policy has resulted in the fragmentation of the state-funded school system and stark variation between academies ...
