Query: Random Matrix Theory Approach to Chaotic Coherent Perfect Absorbers   We employ Random Matrix Theory in order to investigate coherent perfect
absorption (CPA) in lossy systems with complex internal dynamics. The loss
strength $\gamma_{\rm CPA}$ and energy $E_{\rm CPA}$, for which a CPA occurs
are expressed in terms of the eigenmodes of the isolated cavity -- thus
carrying over the information about the chaotic nature of the target -- and
their coupling to a finite number of scattering channels. Our results are
tested against numerical calculations using complex networks of resonators and
chaotic graphs as CPA cavities.
