Matrix model of QCD: Edge localized glueballs and phase transitions

In a matrix model of pure SU(2) Yang-Mills theory, boundaries emerge in the space of Mat3(R) and the Hamiltonian requires boundary conditions. We show the existence of edge localized glueball states that can have negative energies. These edge levels can be lifted to positive energies if the gluons a...

Zusammenfassung:In a matrix model of pure SU(2) Yang-Mills theory, boundaries emerge in the space of Mat3(R) and the Hamiltonian requires boundary conditions. We show the existence of edge localized glueball states that can have negative energies. These edge levels can be lifted to positive energies if the gluons acquire a London-like mass. This suggests a new phase of QCD with an incompressible bulk.
