Determining Rashba spin-orbit coupling strength in InSb nanowire quantum dots: Influence of temperature and nuclear environment⋆
M Milivojević - Physica E: Low-dimensional Systems and …, 2021 - Elsevier
We identify theoretically the possibility to determine the Rashba spin-orbit coupling strength
in InSb nanowire quantum dots by measuring the magnetic susceptibility of the two-electron
system in a double quantum dot. To realistically describe such a system, we study the role of
finite temperature and the interaction of the double quantum dot spins with the nuclear
environment. Magnetic susceptibility, a quantity dependent on the relative angle between
the magnetic and the spin-orbit field, reaches a maximal value when the spin-orbit and …
