Thermal entanglement witness for materials with variable local spin lengths

Andre M. C. Souza, Francisco A. G. Almeida

We show that the thermal entanglement in a spin system using only magnetic susceptibility measurements is restricted to the insulator materials. We develop a generalization of the…

Collapses and revivals of stored orbital angular momentum of light in a cold atomic ensemble

D. Moretti, D. Felinto, J. W. R. Tabosa

We report on the storage of orbital angular momentum of light in a cold ensemble of cesium atoms. We employ Bragg diffraction to retrieve the stored optical information impressed i…
