Exact dynamics in the inhomogeneous central-spin model
Michael Bortz, Joachim Stolze
We study the dynamics of a single spin-1/2 coupled to a bath of spins-1/2 by inhomogeneous Heisenberg couplings including a central magnetic field. This central-spin model describe…

Spin- and entanglement-dynamics in the central spin model with homogeneous couplings
Michael Bortz, Joachim Stolze
We calculate exactly the time-dependent reduced density matrix for the central spin in the central-spin model with homogeneous Heisenberg couplings. Therefrom, the dynamics and the…
