Abstract: | We find exact solutions to the Dirac equation in D-dimensional de Sitter spacetime. Using these solutions we analytically calculate the de Sitter quasinormal (QN) frequencies
of the Dirac field. For the massive Dirac field this computation is similar to that previously published for massive fields
of half-integer spin moving in four dimensions. However to calculate the QN frequencies of the massless Dirac field we must
use distinct methods in odd and even dimensions, therefore the computation is different from that already known for other
massless fields of integer spin. |
