Abstract
A pseudogap is shown to be a magnetic diffuson (MD) in a state with classical localization order coexisting with Quantum Peierls (QP) order. A soft quantum localization mode, a phason, ensures scale invariance with strong correlations among different momentum states seen as a circular Fermi surface with a gap in ARPES when phase fluctuations are random. These correlations imply a state with coexisting order parameters at distinct length scales. Charge quantization and scale invariance accounts for the sharp peak in the excess tunneling current at V=0.
