1305.3877 (David Pérez-García et al.)

The Heisenberg XX spin chain and low-energy QCD    [PDF]

David Pérez-García, Miguel Tierz
By using random matrix models we uncover 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 to relate crucial properties of QCD with physically meaningful properties of the spin chain, establishing a dictionary between both worlds. We postulate that this dictionary goes beyond the particular example analyzed here and can be applied to other QFT and spin chain models.
