alkaline earth compounds

Mold powders are used as raw materials in continuous casting of steel industry; Also they are mostly composed of aluminum, calcium, silica oxides, alkaline and earth-alkaline oxides along with carbon and fluor. Two of the most important duties of mold powders are the lubrication of the space between mold walls and steel shell, and heat transfer control between steel shell and the copper mold. F...

Spectrum Estimation of Density Operators with Alkaline-Earth Atoms.

Journal: :Physical review letters 2018

Michael E Beverland Jeongwan Haah Gorjan Alagic Gretchen K Campbell Ana Maria Rey Alexey V Gorshkov

We show that Ramsey spectroscopy of fermionic alkaline-earth atoms in a square-well trap provides an efficient and accurate estimate for the eigenspectrum of a density matrix whose n copies are stored in the nuclear spins of n such atoms. This spectrum estimation is enabled by the high symmetry of the interaction Hamiltonian, dictated, in turn, by the decoupling of the nuclear spin from the ele...
