Quantum catastrophes Duncan O’Dell (McMaster University) Catastrophe theory provides a unified description of a broad range of singularities and defects in fields and has been applied extensively in optics. A key idea is that of scale: at large scales the catastrophe appears singular but at smaller scales it is smoothed, e.g. by wave interference. In […]

The hydraulic analogy to superfluid-like dispersive hydrodynamics Mark Hoefer (Department of Applied Mathematics, University of Colorado,  Boulder, USA) The classic « hydraulic analogy » between supercritical shallow water flows and gas dynamics was leveraged in the early to mid 20th century as a means to model the flow patterns around wings with a relatively simple water table.
