Hyperfine interaction and electron-spin decoherence in graphene and carbon nanotube quantum dots
Jan Fischer, Bjoern Trauzettel, Daniel Loss
We analytically calculate the nuclear-spin interactions of a single electron confined to a carbon nanotube or graphene quantum dot. While the conduction-band states in graphene are…
Spin interactions, relaxation and decoherence in quantum dots
Jan Fischer, Mircea Trif, W. A. Coish +1
We review recent studies on spin decoherence of electrons and holes in quasi-two-dimensional quantum dots, as well as electron-spin relaxation in nanowire quantum dots. The spins o…
Spin decoherence of a heavy hole coupled to nuclear spins in a quantum dot
Jan Fischer, W. A. Coish, D. V. Bulaev +1
We theoretically study the interaction of a heavy hole with nuclear spins in a quasi-two-dimensional III-V semiconductor quantum dot and the resulting dephasing of heavy-hole spin…
Exponential decay in a spin bath
W. A. Coish, Jan Fischer, Daniel Loss
We show that the coherence of an electron spin interacting with a bath of nuclear spins can exhibit a well-defined purely exponential decay for special (`narrowed') bath initial co…
