Query: Fermion Condensation Quantum Phase Transition versus Conventional
  Quantum Phase Transitions   The main features of fermion condensation quantum phase transition (FCQPT),
which are distinctive in several aspects from that of conventional quantum
phase transition (CQPT), are considered. We show that in contrast to CQPT,
whose physics in quantum critical region is dominated by thermal and quantum
fluctuations and characterized by the absence of quasiparticles, the physics of
a Fermi system near FCQPT or undergone FCQPT is controlled by the system of
quasiparticles resembling the Landau quasiparticles. Contrary to the Landau
quasiparticles, the effective mass of these quasiparticles strongly depends on
the temperature, magnetic fields, density, etc. This system of quasiparticles
having general properties determines the universal behavior of the Fermi system
in question. As a result, the universal behavior persists up to relatively high
temperatures comparatively to the case when such a behavior is determined by
CQPT. We analyze striking recent measurements of specific heat, charge and heat
transport used to study the nature of magnetic field-induced QCP in
heavy-fermion metal CeCoIn$_5$ and show that the observed facts are in good
agreement with our scenario based on FCQPT and certainly seem to rule out the
critical fluctuations related with CQPT. Our general consideration suggests
that FCQPT and the emergence of novel quasiparticles near and behind FCQPT and
resembling the Landau quasiparticles are distinctive features intrinsic to
strongly correlated substances.
