Query: Greybody Factors of Holographic Superconductors with $z=2$ Lifshitz
  Scaling   We study the quasinormal modes and thermal radiation of massless spin-0 field
perturbations in the background of four-dimensional (4D) non-Abelian charged
Lifshitz black branes with $z=2$ hyperscaling violation, which correspond to
systems with superconducting fluctuations. After having an analytical solution
to the Klein-Gordon equation, we obtain exact quasinormal modes that are purely
imaginary. Therefore, there is no oscillatory behavior in the perturbations
that guarantees the mode stability of these solutions. We also study the
greybody factors, absorption cross-section, and decay rate of the non-Abelian
charged Lifshitz black branes. We derive their analytical expressions and then
investigate the correspondence in the strongly coupled dual theory. This study
might shed light on the mechanism governing the high-temperature
superconductors in condensed matter physics.
