Following a recent proposal by Dhar et al (2006
Phys. Rev. Lett. 96 100405), we demonstrate experimentally
the preservation of quantum states in a two-qubit system based on a
super-Zeno effect using liquid-state nuclear magnetic resonance
techniques. Using inverting radiofrequency pulses and delic...

We study (Ga, Mn)As diluted magnetic semiconductors in
terms of the Ruderman--Kittel--Kasuya--Yosida quantum spin model in
Green's function approach. Random distributions of the magnetic
atoms are treated by using an analytical average of magnetic
configurations. Average magnetic moments and spin ex...
