Universal horizons and Hawking radiation in nonprojectable 2d Hořava gravity coupled with a non-relativistic scalar field

Bao-Fei Li, Madhurima Bhattacharjee, Anzhong Wang

In this paper, we study the non-projectable 2d Hořava gravity coupled with a non-relativistic scalar field, where the coupling is in general non-minimal and of the form $f(\varphi )R$, wh…
