32. Spacetime Charge and The End of Predictability

Idrus Husin Belfaqih (University of Edinburgh)

Long Talk (20 mins)

A novel theory has recently surfaced, proposing a generically covariant and anomaly-free canonical modified theory of gravity. This theory posits the emergence of a spacetime line element from phase space variables by ensuring the covariance of the metric components. Besides the holonomy-like correction resembling correction in the effective loop quantum cosmology, anomaly-free condition...

36. Stability of Quantised Vortices in Two-Component Condensates

Ansh Gupta (King's College London)

Long Talk (20 mins)

Vortices in quantum fluids, such as Bose-Einstein condensates, have discrete charges associated with their circulations. Higher charged quantum vortices have dynamical instabilities which arise from bound states inside the vortex core, resulting in vortex splitting. These multiply charged quantum vortices can be stabilised by adding a second component to the condensate. This talk will...
