The phonon mass and the Hawking temperature in the two-dimensional acoustic black hole model
In this paper, the acoustic metric and effective action are derived by using the shift transformation and functional integrals method, this metric can describe the fluctuation of the phonon fields in the quantum fluid. When the phonon fields are coupled with different types of 2-D gravity, i.e., Jac...
