Many-impurity scattering on the surface of a topological insulator
José Luis Hernando, Yuriko Baba, Elena Díaz +1
We theoretically address the impact of a random distribution of non-magnetic impurities on the surface states formed at the interface between a trivial and a topological insulator.…
Rashba coupling and spin switching through surface states of Dirac semimetals
Yuriko Baba, Francisco Domínguez-Adame, Gloria Platero +1
We study the effect of the Rashba spin-orbit coupling on the Fermi arcs of topological Dirac semimetals. The Rashba coupling is induced by breaking the inversion symmetry at the su…
Spin-dependent electronic lenses based on hybrid graphene nanostructures
Yuriko Baba, Marta Saiz-Bretín
We study electronic transport in graphene/ferromagnetic insulator hybrid devices. The system comprises an armchair graphene nanoribbon with a lens-shaped EuO ferromagnetic insulato…
Electric field manipulation of surface states in topological semimetals
Yuriko Baba, Álvaro Díaz-Fernández, Elena Díaz +2
We investigate the consequences of applying electric fields perpendicularly to thin films of topological semimetals. In particular, we consider Weyl and Dirac semimetals in a confi…
Parisi States in a Heisenberg Spin-Glass Model in Three Dimensions
F. Matsubara, T. Shirakura, Y. Baba
We have studied low-lying metastable states of the Heisenberg model in two () and three () dimensions having developed a hybrid genetic algorithm. We have found a…
