Valley physics in the two bands $\mathbf{k}\cdot \mathbf{p}$ model for SiGe heterostructures and spin qubits

Tancredi Salamone, Biel Martinez Diaz, Jing Li +2

We discuss the choice and implementation of inter-valley potentials in the so-called two bands $\mathbf{k}\cdot \mathbf{p}$ model for the opposite $X$, $Y$ or $Z$ valleys of silicon…
