Non-perturbative theory of valley splitting in Si qubits from variational wave function: periodic effects of shear strain and asymptotic freedom in the wiggle-well potential
Johannes L. P. Steinschuld, Hendrik J. Bluhm, Seyed Akbar Jafari
Valley splitting sets the energy scale at which spin and valley degrees of freedom hybridize in silicon quantum-well qubits, but its sensitivity to interface structure makes it dif…

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…
