Comment on "Nonlocal Coherent Perfect Absorption"
arXiv:1912.08194
Abstract
We show that, contrary to what is claimed in Ref. [J. Jeffers, Phys. Rev. Lett. 123, 143602 (2019)], there is no nonlocal coherent absorption by the two lossy beam splitters considered in detail in the treatment of the setup presented in this reference. What happens is a local coherent absorption by the other two lossy beam splitters of the setup.
