Query: Two-component energy spectrum of cuprates in the pseudogap phase and its
  evolution with temperature and at charge ordering   In the search for mechanisms of high-temperature superconductivity it is
critical to know the electronic spectrum in the pseudogap phase from which
superconductivity evolves. The lack of angle-resolved photoemission data for
every cuprate family precludes an agreement as to its structure, doping and
temperature dependence and the role of charge ordering. Here we show that, in
the entire Fermi-liquid-like regime that is ubiquitous in underdoped cuprates,
the spectrum consists of holes on the Fermi arcs and an electronic pocket. We
argue that experiments on the Hall coefficient identify the latter as a
permanent feature at doped hole concentration x>0.08-0.10, in contrast to the
idea of the Fermi surface reconstruction via charge ordering. The longstanding
issue of the origin of the negative Hall coefficient in YBCO and Hg1201 at low
temperature is resolved: the electronic contribution prevails as mobility of
the latter (evaluated by the Dingle temperature) becomes temperature
independent, while the mobility of holes scattered by the short-wavelength
charge density waves decreases.
