Effective damping in the Raman cooling of trapped ions
A. B. Klimov, J. L. Romero, J. Delgado +1
We present a method of treating the interaction of a single three-level ion with two laser beams. The idea is to apply a unitary transformation such that the exact transformed Hami…
Phase states for a three-level atom interacting with quantum fields
A. B. Klimov, L. L. Sanchez-Soto, J. Delgado +1
We introduce phase operators associated with the algebra su(3), which is the appropriate tool to describe three-level systems. The rather unusual properties of this phase are cause…
A description of entanglement in terms of quantum phase
Luis L. Sanchez-Soto, Julian Delgado, Andrei B. Klimov +1
We explore the role played by the phase in an accurate description of the entanglement of bipartite systems. We first present an appropriate polar decomposition that leads to a tru…
