Phys. Rev. D 74, 043501 (2006) [6 pages]Tachyon matter in loop quantum cosmologyReceived 21 April 2006; published 1 August 2006 An analytical approach for studying the cosmological scenario with a homogeneous tachyon field within the framework of loop quantum gravity is developed. Our study is based on the semiclassical regime where space time can be approximated as a continuous manifold, but matter Hamiltonian gets nonperturbative quantum corrections. A formal correspondence between classical and loop quantum cosmology is also established. The Hamilton-Jacobi method for getting exact solutions is constructed and some exact power law as well as bouncing solutions are presented. © 2006 The American Physical Society URL:
