Spintronics in low-dimensional heterostructures: a symmetry-based perspective.
Marta Prada
Departamento de Física
Universidad de Hamburgo
In this talk, I will present two lines of research concerning spintronics,
both by employing symmetry arguments.
The first concerns Si/SiGe heterostructures, where origin of the valley degree
of freedom is introduced by using symmetry arguments. Applications in
spintronics and numerical results will also be given.
The second part is dedicated to spin adatoms in non-magnetic surfaces, where
the protection mechanisms have been recently attributed to a non-trivial Berry
phase arising from the particular spin and point group symmetry combination.
