dc.descriptionWe argue that in strongly correlated electron system collective instanton excitations of the phase field (dual to the charge) arise with a great degree of stability, governed by gauge flux changes by an integer multiple of $2π$. By unraveling consequences of the non-trivial topology of the charge gauge U(1) group, we found that the pinning of $μ$ and the zero-temperature divergence of charge compressibility $κ\sim\partial n_e/\partialμ$ defines novel "hidden" quantum criticality on verge of the Mott transition governed by the protectorate of stable topological numbers rather than Landau paradigm of the symmetry breaking.
