Valley-Enabled Intrinsic Dresselhaus Spin-Orbit Coupling in Silicon
Johannes L. P. Steinschuld, Hendrik J. Bluhm, Lars R. Schreiber +1
We develop a symmetry-based theory of spin-orbit-valley coupling in silicon that reveals an intrinsic source of Dresselhaus spin-orbit coupling independent of interfaces or externa…

Zeeman-like coupling to valley degree of freedom in Si-based spin qubits
S Akbar Jafari, Hendrik J Bluhm, David P Divincenzo
Increasing the valley splitting in Si-based heterostructures is critical for improving the performance of semiconductor qubits. This paper demonstrates that the two low-energy cond…
