Query: Multipole excitations in hot nuclei within the finite temperature
  quasiparticle random phase approximation framework   The effect of temperature on the evolution of the isovector dipole and
isoscalar quadrupole excitations in $^{68}$Ni and $^{120}$Sn nuclei is studied
within the fully self-consistent finite temperature quasiparticle random phase
approximation framework, based on the Skyrme-type SLy5 energy density
functional. The new low-energy excitations emerge due to the transitions from
thermally occupied states to the discretized continuum at finite temperatures,
whereas the isovector giant dipole resonance is not strongly impacted by the
increase of temperature. The radiative dipole strength at low-energies is also
investigated for the $^{122}$Sn nucleus, becoming compatible with the available
experimental data when the temperature is included. In addition, both the
isoscalar giant quadrupole resonance and low-energy quadrupole states are
sensitive to the temperature effect: while the centroid energies decrease in
the case of the isoscalar giant quadrupole resonance, the collectivity of the
first $2^{+}$ state is quenched and the opening of new excitation channels
fragments the low-energy strength at finite temperatures.
