By using random matrix models Perez-García and Tierz uncover in their new paper in PRX a connection between the low energy sector of four dimensional QCD at finite volume and the Heisenberg XX model in a 1d spin chain. This connection allows them to relate crucial properties of QCD with physically meaningful properties of the spin chain, establishing a dictionary between both worlds. They predict for the spin chain a third-order phase transition and a Tracy-Widom law in the transition region. Finally they comment on possible numerical implications of the connection as well as on possible experimental implementations.
Carlos Fernández defended his PhD dissertation. Congratulations to the new doctor!
