Decoherence from an antiferromagnetic environment
Xiao-Zhong Yuan, Ka-Di Zhu · Europhysics Letters (EPL) · 2005
The decoherence of a central spin in an antiferromagnetic environment is investigated theoretically in terms of the spin wave approximation. It is analytically shown that the decoherence factor which displays a Gaussian decay strongly depends on the quantum correlations and the structure of the environment. The relation between the decoherence factor and the environmental temperature is also given explicitly.
