  The synergistic formation of ``zero'' (exponentially small or thermally
activated) resistance states (ESRS) in high mobility two-dimensional electron
systems (2DES) in a static magnetic field B and exposed to strong microwave
radiation has attracted great interest. Strong (glassy) disorder apparently
stabilizes the new synergistic phase, which can be exactly described by a
nonperturbative (nonpolynomial) microscopic topological filamentary model. The
model contains many novel features that arise from strong correlations,
nanoscopic phase separation, and quasi-one dimensional back scattering.
