• Horava-Lifshitz gravity
• Quasinormal modes
• Area spectrum

The Dirac quasinormal modes of Horava-Lifshitz black holes are studied. We find that the QNMs are purely damped modes which means the spacetimes are very stable. For the fundamental frequencies, we note that the absolute value of the frequencies increases as the orbital angular moment I increases, which means that the Dirac perturbations decay quickly for the larger I modes. For the high overtone number modes, we show that the QNMs frequencies are linearly related to the Hawking temperature. Therefore, using Kunstatter's approach we find that the area spacing of the Horava-Lifshitz black hole is described by Delta A(min) = 8 pi h which supports Bekenstein's conjecture.
