Slow Light amplification in a non-inverted gain medium
Filippo Caruso, Ivan Herrera, Saverio Bartalini +1
We investigate the propagation of a coherent probe light pulse through a three-level atomic medium (in the --configuration) in the presence of a pump laser under the conditions…

Entanglement and factorized ground states in two-dimensional quantum antiferromagnets
Tommaso Roscilde, Paola Verrucchi, Andrea Fubini +2
Making use of exact results and quantum Monte Carlo data for the entanglement of formation, we show that the ground state of anisotropic two-dimensional S=1/2 antiferromagnets in a…
