From Dirac to Diffusion: Decoherence in Quantum Lattice Gases.

Love, Peter J.

Boghosian, Bruce M.


  • We describe a model for the interaction of the internal (spin) degree of freedom of a quantum lattice-gas particle with an environmental bath. We impose the constraints that the particle-bath interaction be fixed, while the state of the bath is random, and that the effect of the particle-bath interaction be parity invariant. The condition of parity invariance defines a subgroup of the unitary grou... read more
