Stabilization of quantum properties under intrinsic decoherence in presence of external magnetic fields

Abstract

The dynamical behavior of quantum state properties under intrinsic decoherence models can be modified by the presence of external magnetic fields. Although generically external magnetic fields are detrimental to preserve quantumness in the presence of intrinsic decoherence, judicious adjustment of the magnetic field can stabilize such features. This stabilization arises from novel resonances between energy eigenstates resulting from the presence of an external magnetic field. Here, we present our findings using as a model system two spin 1-particles confined in a double-well potential under intrinsic decoherence. We stress, however, that our results are generic and independent on the used model.
