Effect of the external fields in high Chern number quantum anomalous Hall insulators
Yuriko Baba, Mario Amado, Enrique Diez +2
A quantum anomalous Hall state with high Chern number has so far been realized in multiplayer structures consisting of alternating magnetic and undoped topological insulator layers…
Generation and control of non-local chiral currents in graphene superlattices by orbital Hall effect
Juan Salvador-Sánchez, Luis M. Canonico, Ana Pérez-Rodríguez +15
Graphene-based superlattices offer a new materials playground to exploit and control a higher number of electronic degrees of freedom, such as charge, spin, or valley for disruptiv…
Impact of electron-electron interactions on the thermoelectric efficiency of graphene quantum point contacts
Irián Sánchez-Ramírez, Yuriko Baba, Leonor Chico +1
Thermoelectric materials open a way to harness dissipated energy and make electronic devices less energy-demanding. Heat-to-electricity conversion requires materials with a strongl…
Persistence of symmetry-protected Dirac points at the surface of the topological crystalline insulator SnTe upon impurity doping
Olga Arroyo-Gascón, Yuriko Baba, Jorge I. Cerdá +4
We investigate the effect of a non-magnetic donor impurity located at the surface of the SnTe topological crystalline insulator. In particular, the changes on the surface states du…
Tailoring topological states of core-shell nanoparticles
Carolina Martínez-Strasser, Yuriko Baba, Álvaro Díaz-Fernández +1
In this work we investigate novel spherical core-shell nanoparticles with band inversion. The core and the embedding medium are normal semiconductors while the shell material is as…
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…
