Holographic study on Einstein ring for a charged black hole in conformal gravity ...
With the help of AdS/CFT correspondence, the Einstein ring of a charged black hole in conformal gravity has been studied. Imposing an oscillating Gauss source on one side of the AdS boundary which propagates in the bulk, we derive the response function on the other side of the boundary. With the pro...

With the help of AdS/CFT correspondence, the Einstein ring of a charged black hole in conformal gravity has been studied. Imposing an oscillating Gauss source on one side of the AdS boundary which propagates in the bulk, we derive the response function on the other side of the boundary. With the proposed wave optics system, we observe the Einstein ring as expect. The results reveal that when the observer locates at the north pole, the Einstein ring and surrounding concentric stripes always exist. While the observer departs away from the north pole, the ring becomes into a luminosity-deformed ring or light spot. We also investigate the effect of temperature $T$, chemical potential $u$ and gravity-related parameters $c_0$ on the ring radius.
