摘要
In this paper, investigate how a uniformly accelerated detector responds to vacuum state of a Dirac field in the kappa-Minkowski spacetime. Starting from a-deformed Dirac theory, which is invariant under kappa-Poincare algebra, we derive kappa-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 kappa-spacetime. Prom this, we obtain the modification to Unruh effect for the kappa-deformed Dirac field, valid up to first-order in the deformation parameter.
