Nuclear Spins in Nanostructures
W. A. Coish, J. Baugh
We review recent theoretical and experimental advances toward understanding the effects of nuclear spins in confined nanostructures. These systems, which include quantum dots, defe…
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…
Stationary and transient leakage current in the Pauli spin blockade
F. Qassemi, W. A. Coish, F. K. Wilhelm
We study the effects of cotunneling and a non-uniform Zeeman splitting on the stationary and transient leakage current through a double quantum dot in the Pauli spin blockade regim…
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…
Nuclear spin dynamics and Zeno effect in quantum dots and defect centers
D. Klauser, W. A. Coish, Daniel Loss
We analyze nuclear spin dynamics in quantum dots and defect centers with a bound electron under electron-mediated coupling between nuclear spins due to the hyperfine interaction ("…
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…
