Abstract
In this paper, we investigate how a uniformly accelerated detector responds to vacuum state of a Dirac field in the κ-Minkowski spacetime. Starting from κ-deformed Dirac theory, which is invariant under κ-Poincaré algebra, we derive κ-deformed Wightman function for Dirac field, which is valid up to first-order in the deformation parameter a. Using this, we calculate the response function of the uniformly accelerated detector, which is coupled to massless Dirac field in κ-spacetime. From this, we obtain the modification to Unruh effect for the κ-deformed Dirac field, valid up to first-order in the deformation parameter.
