An online staff briefing on proposals for a temporary congestion charge in Oxford have been arranged with the County Council. This will take place at 11.30am-12.30pm on Monday 30 June. Colleagues interested in the proposals and their potential impact are welcome to join using the Teams links provided.
Following a University-wide communications survey in January 2025, the Internal Communications team is inviting staff to take part in follow-up discussion groups or share their views through a short, anonymous questionnaire during July. The aim is to gather more nuanced feedback that will help shape how the University communicates with staff in the future.

Anomalies of Defect Parameter Spaces and a Spin-Flux Duality
Abstract
I will explain how the irreversibility of the renormalization group together with anomalies, including anomalies in the space of coupling constants, can be used to constrain the IR phases of defects in familiar quantum field theories. As an example, I will use these techniques to provide evidence for a conjectural "spin-flux duality" which describes how certain line operators are mapped across particle/vortex duality in 2+1d.
