DESCRIPTION:Speakers: Chris Allton (Swansea University)\n\nUnderstanding t
 he cause of confinement in QCD is one of the central\, unsolved problems i
 n particle physics. A compelling explanation can be constructed using cent
 re vortices\, topological structures in the gluon fields analogous to the 
 twist in a Möbius strip. In earlier work\, we revealed three “phases”
  of QCD with two transition temperatures. The first is the usual chiral tr
 ansition\, $T_c$\, and the second at $T_d\\sim 1.9T_c$ has deconfinement p
 roperties. In this work\, we find that topological data analysis applied t
 o the centre vortex sheets can distinguish these phases. Below $T_c$\, vor
 tex sheets are highly crumpled and topological features are temperature in
 variant. In the warm “phase” between $T_c$ and $T_d$\, the topology of
  the vortex sheets has modest changes and there are the first signs of ani
 sotropy. Above $T_d$ there is a dramatic change in the centre vortex sheet
 s’ topology. Percolation properties change\, vortex sheets are temporall
 y aligned\, and the area law is lost\, signally deconfinement.\n\nhttps://
