Beyond Analog Gravity: The Case of Exceptional Dynamics
Abstract
We show that it is possible to go beyond the simple kinematical aspects of the analog models of gravity. We exhibit the form of the Lagrangian that describes the dynamics of a self-interacting field $ ϕ$ as an interaction between $ ϕ$ and its associated effective metric $ \hat{g}^{μν}.$ In other words the non-linear equation of motion of the field may be interpreted as the gravitational influence on $ ϕ$ by its own effective metric which, in our scheme becomes an active partner of the dynamics of $ ϕ. $
