# phys: a holographic image of a black hole

<< by applying a magnetic field to a small, irregularly shaped graphene flake, the flake becomes a quantum hologram of a black hole. This means that the graphene flake recreates the spatial structure and characteristic properties of a black hole, but in a much smaller, lower-dimensional system. >>

<< The type of holographic duality illustrated by the SYK [Sachdev-Ye-Kitaev] model is particularly interesting because it exhibits some of the signature properties of black holes, such as non-zero residual entropy and quantum chaos propagation. >>
