A bstract Taking into account that the real quantum materials are engineered generically at a finite chemical potential, we investigate Einstein ring structure for lensed response of complex scalar field as probe wave on charged AdS black hole in context AdS/CFT. On one hand, find resulting radius has no variation with which is similar to behavior weakly interacting system. other not only can such exist well within screen, but also temperature dependence its exhibits distinct feature sense it displays an appreciable increase low temperatures while keeps unchanged right edge screen Note emerges large frequencies and be captured by photon sphere away from horizon geometric optics approximation, thus may regarded universal associated high energy modes strongly coupled system gravity dual.
