Key word is "mimics."
This is interesting for several reasons:
1) It's not literally a black hole gravitationally. It's only a simulation - optical analog.
2) However, it is a potential test bed to see who is correct on the issue
(index of refraction)^4G/c^4 ?
There is no meta-material negative near field EM energy density here so no anti-gravity to be expected. However, if I am right then there should be a brief attractive gravity anomaly during the RIP laser pulse - though still very tiny and possibly not easy to detect - I have not tried to plug in the numbers.
3) Note on my hypothetical half-baked anti-gravity graphene sheet lifter all we need is negative static permittivity and the super-conducting meta-material high-voltage capacitor should anti-gravitate.
Getting a huge negative electrostatic polarization in the active material not easy, but maybe there is a way - note nonlinear optics can give a static term.

Note, however, the actual experiment below is no good because the change in index of refraction is only 1% - we need the superconductor (or BE condensate in general).

Thanks very much. You may also want to look up Proton 21 out of Kiev where they created minature black holes several years ago in repeatable experiments... Tim Ventura first talked about these...

"Manmade Black Holes
Hawking radiation (little sideways moving balls) is created when a powerful and brief pulse of light (black arrows) is sent through a sample of pure glass. The pulse instantaneously changes the optical conditions in the glass to such a degree that the light seems to come to a halt, represented by the green-shaded warped tiling.

The change in the refraction index occurs in lockstep with the laser pulse as it passes through the glass. The resulting moving disturbance is referred to as RIP, the refractive index perturbation. The RIP happens not because of the energy of the laser pulse, and not even because of the size of the change in the refractive index (which is less than 1 percent), but because of the quickness of the change, occurring over mere picoseconds (trillionths of a second)."
