Abstract: We show that in van der Waals stacks of twisted hexagonal layers the proximity induced Rashba spin-orbit coupling can be affected by quantum interference.We calculate the quantum phase responsible for this effect in graphene-transition metal dichalcogenide bilayers as a function of interlayer twist angle.We show how this quantum phase affects the spin polarization of the graphene bands and discuss its potential effect on spin-tocharge conversion measurements.In twisted trilayers symmetries can be broken as well as restored for certain twist angles.This can be used to deduce the effects of induced spin-orbit coupling on spin-lifetime anisotropy and magnetoconductance measurements.
