Importance of bath dynamics for decoherence in spin systems
Shengjun Yuan, Mikhail I. Katsnelson, Hans De Raedt
We study the decoherence of two coupled spins that interact with a chaotic spin-bath environment. It is shown that connectivity of spins in the bath is of crucial importance for th…

Evolution of a quantum spin system to its ground state: Role of entanglement and interaction symmetry
S. Yuan, M. I. Katsnelson, H. De Raedt
We study the decoherence of two ferro- and antiferromagnetically coupled spins that interact with a frustrated spin-bath environment in its ground state. The conditions under which…
