Phys. Rev. D 71, 065015 (2005) [4 pages]Quantum uncertainty in doubly special relativityReceived 11 June 2004; revised 9 February 2005; published 28 March 2005 A discussion of the modification of the phase-space commutators in a quantum mechanical relativistic theory with an invariant length scale (DSR) is presented. Two examples are discussed where a classical behavior is approached in one case when the energy approaches the inverse of the invariant length which appears as a cutoff in the energy and in the second case when the mass is much larger than the inverse of the invariant length. © 2005 The American Physical Society URL:
