  We investigate detection of Dirac quanta in a uniformly eccentric rotating
frame both with canonical and detector approaches by employing relativistic
rotational transformations. First we consider a relativistic uniformly
eccentric rotating detector that is coupled to the scalar density of a massless
Dirac field, and show that this detector has a nonzero response function and
observes a Planckian energy spectrum. Then using relativistic rotational
transformations, we investigate the canonical quantization of Dirac field in
relativistic eccentric rotating frame. We show that it's not possible to obtain
the analytic solution for Dirac equation in this frame and so canonical
approach can not be carried out.
