  Assuming that high energy effects may alter the standard dispersion relations
governing quantized fields, the influence of such modifications on various
phenomena has been studied extensively in the literature. In different
contexts, it has generally been found that, while super-luminal dispersion
relations hardly affect the standard results, sub-luminal relations can lead to
(even substantial) modifications to the conventional results. A polymer
quantized scalar field is characterized by a series of modified dispersion
relations along with suitable changes to the standard measure of the density of
modes. Amongst the modified dispersion relations, one finds that the lowest in
the series can behave sub-luminally over a small domain in wavenumbers. In this
work, we study the response of a uniformly rotating Unruh-DeWitt detector that
is coupled to a polymer quantized scalar field. While certain sub-luminal
dispersion relations can alter the response of the rotating detector
considerably, in the case of polymer quantization, due to the specific nature
of the dispersion relations, the modification to the transition probability
rate of the detector does not prove to be substantial. We discuss the wider
implications of the result.
