A Note on Analogue Semi-Classical Gravity in (\(\boldsymbol{1+1}\)) Dimensions

Acoustic space-times have been known to offer analogue models for black hole physics and cosmology. Within this context, aspects of analogue quantum field theories in curved space-time are studied. In particular, some new comments have been made on the analogue Hawking temperature including a quick derivation of the result. Further, analogue cosmology is explored, within which an acoustic version of the Parker–Toms model is proposed, and the corresponding quantities are calculated. The limits of the acoustic analogue are emphasized.
