Title:  Analogue gravity versus real gravity

 

Abstract: Although analogue gravity appeared in non-gravitational systems show many features resemble to real gravitational systems such as the appearance of curved geometry and horizon, their underlying dynamics look rather different from that of the real gravity and hence they were merely treated as analogous models from the conventional viewpoint. However, in this talk, we will show that, the two systems can indeed be connected with each other from a holographic viewpoint. We will give three examples to illustrate their connection.
