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…
Topological valley currents via ballistic edge modes in graphene superlattices near the primary Dirac point
Yang Li, Mario Amado, Timo Hyart +2
Graphene on hexagonal boron nitride (hBN) can exhibit a topological phase via mutual crystallographic alignment. Recent measurements of nonlocal resistance () near the seco…
Magnetically-driven colossal supercurrent enhancement in InAs nanowire Josephson junctions
J. Paajaste, E. Strambini, M. Amado +7
The Josephson effect is a fundamental quantum phenomenon consisting in the appearance of a dissipationless supercurrent in a weak link between two superconducting (S) electrodes. W…
Pb/InAs nanowire Josephson junction with high critical current and magnetic flux focusing
J. Paajaste, M. Amado, S. Roddaro +4
We have studied mesoscopic Josephson junctions formed by highly -doped InAs nanowires and superconducting Ti/Pb source and drain leads. The current-voltage properties of the sys…
Electrostatic tailoring of magnetic interference in quantum point contact ballistic Josephson junctions
M. Amado, A. Fornieri, F. Carillo +4
The magneto-electrostatic tailoring of the supercurrent in quantum point contact ballistic Josephson junctions is demonstrated. An etched InAs-based heterostructure is laterally co…
