Phys. Rev. D 76, 127701 (2007) [3 pages]Relativistic ideal Fermi gas at zero temperature and preferred frameReceived 20 September 2007; published 12 December 2007 We discuss the limit T→0 of the relativistic ideal Fermi gas of luxons (particles moving with the speed of light) and tachyons (hypothetical particles faster than light) based on observations of our recent paper: K. Kowalski, J. Rembieliński and K. A. Smoliński Phys. Rev. D 76 045018 (2007). For bradyons this limit is in fact the nonrelativistic one and therefore it is not studied herein. © 2007 The American Physical Society URL:
