Computing the Photometric and Polarimetric Variability of Be Stars
Keegan C. Marr, C. E. Jones, R. J. Halonen
We investigate variations in the linear polarization as well as in the V-band and B-band colour-magnitudes for classical Be star disks. We present two models: disks with enhanced d…

Quantum caustics and the hierarchy of light cones in quenched spin chains
W. Kirkby, J. Mumford, D. H. J. O'Dell
We show that the light cone-like structures that form in spin chains after a quench are quantum caustics. Their natural description is in terms of catastrophe theory and this impli…
