Preservation of atomic coherence in double-well optical lattice in presence of decoherence
arXiv:1002.1135
Abstract
We present a quantum interference approach to preserve coherence in the external states of an atom trapped in an optical lattice. We show that this is possible by suitably choosing the initial state of the atom. We demonstrate this in context of decoherence due to spontaneous emission in an one-dimensional optical double-well lattice.
