On quantum critical destruction of the pseudogap phase

Recent data on the critical events accompanying the quenching of the pseudogap (PG) phase in hole-doped cuprates are analysed. An original multiband model with the spectrum influenced by doping has been used. Two critical dopings are expected in evolving of the PG to destruction. The first of them corresponds to metallization (antinodal) of the sample. Extended doping leads to a second critical point where the PG is lost. In between the restoration of the full Fermi surface proceeds. Band overlaps besides the location of the chemical potential (μ) are decisive.
