DESCRIPTION:It is well known that an ideal detector moving on an accelerat
 ed trajectory in Minkowski space registers an exactly thermal bath of radi
 ation. This result relies upon (among other things) the linear dispersion 
 displayed by a relativistic scalar field. However\, there are reasons to b
 elieve that local Lorentz invariance does not hold above a certain energy 
 scale\, when perturbative effects of a yet unknown quantum gravity are no 
 longer negligible. We therefore consider the Unruh effect in the presence 
 of Lorentz-breaking\, non-linear dispersion relations\, and we show that t
 he corrections to the thermal spectrum are exponentially suppressed\, in l
 ine with the robustness of Hawking radiation.\n\nhttps://indico.ific.uv.es
