Hyperfine induced electron spin and entanglement dynamics in double quantum dots: The case of separate baths
Bjoern Erbe, John Schliemann
We consider a system of two strongly coupled electron spins in zero magnetic field, each of which is interacting with an individual bath of nuclear spins via the hyperfine interact…
Perturbative regimes in central spin models
Bjoern Erbe, John Schliemann
Central spin models describe several types of solid state nanostructures which are presently considered as possible building blocks of future quantum information processing hardwar…
Swapping and entangling hyperfine coupled nuclear spin baths
Bjoern Erbe, John Schliemann
We numerically study the hyperfine induced nuclear spin dynamics in a system of two coupled quantum dots in zero magnetic field. Each of the electron spins is considered to interac…
Unexpected systematic degeneracy in a system of two coupled Gaudin models with homogeneous couplings
Bjoern Erbe, John Schliemann
We report an unexpected systematic degeneracy between different multiplets in an inversion symmetric system of two coupled Gaudin models with homogeneous couplings, as occurring fo…
Different types of integrability and their relation to decoherence in central spin models
B. Erbe, J. Schliemann
We investigate the relation between integrability and decoherence in central spin models with more than one central spin. We show that there is a transition between integrability e…
Hyperfine induced spin and entanglement dynamics in Double Quantum Dots: A homogeneous coupling approach
Bjoern Erbe, John Schliemann
We investigate hyperfine induced electron spin and entanglement dynamics in a system of two quantum dot spin qubits. We focus on the situation of zero external magnetic field and c…
