Observation of Weyl nodes in robust type-II Weyl semimetal WP2
M. -Y. Yao, N. Xu, Q. Wu +9
Distinct to type-I Weyl semimetals (WSMs) that host quasiparticles described by the Weyl equation, the energy dispersion of quasiparticles in type-II WSMs violates Lorentz invarian…
Electronic properties of one-dimensional nanostructures of the BiSe topological insulator
Naunidh Virk, Gabriel Autès, Oleg V. Yazyev
We theoretically study the electronic structure and spin properties of one-dimensional nanostructures of the prototypical bulk topological insulator BiSe. Realistic models…
Distinct evolutions of Weyl fermion quasiparticles and Fermi arcs with bulk band topology in Weyl semimetals
N. Xu, G. Autes, C. E. Matt +14
The Weyl semimetal phase is a recently discovered topological quantum state of matter characterized by the presence of topologically protected degeneracies near the Fermi level. Th…
Localized electronic states at grain boundaries on the surface of graphene and graphite
Adina Luican-Mayer, Jose E. Barrios-Vargas, Jesper Toft Falkenberg +8
Recent advances in large-scale synthesis of graphene and other 2D materials have underscored the importance of local defects such as dislocations and grain boundaries (GBs), and es…
Robust Type-II Weyl Semimetal Phase in Transition Metal Diphosphides XP (X = Mo, W)
G. Autès, D. Gresch, M. Troyer +2
The recently discovered type-II Weyl points appear at the boundary between electron and hole pockets. Type-II Weyl semimetals that host such points are predicted to exhibit a new t…
Electromechanical Oscillations in Bilayer Graphene
Muhammed Malik Benameur, Fernando Gargiulo, Sajedeh Manzeli +4
Nanoelectromechanical systems (NEMS) constitute a class of devices lying at the interface between fundamental research and technological applications. Integrating novel materials s…
Electronic Transport in Graphene with Aggregated Hydrogen Adatoms
Fernando Gargiulo, Gabriel Autès, Naunidh Virk +5
Hydrogen adatoms and other species covalently bound to graphene act as resonant scattering centers affecting the electronic transport properties and inducing Anderson localization.…
Strong out-of-plane magnetic anisotropy of Fe adatoms on BiTe
T. Eelbo, M. Waśniowska, M. Sikora +7
The electronic and magnetic properties of individual Fe atoms adsorbed on the surface of the topological insulator BiTe(111) are investigated. Scanning tunneling microscopy…
Atomic and Electronic Structure of a Rashba - Junction at the BiTeI Surface
C. Tournier-Colletta, G. Autès, B. Kierren +6
The non-centrosymmetric semiconductor BiTeI exhibits two distinct surface terminations that support spin-split Rashba surface states. Their ambipolarity can be exploited for creati…
Engineering Quantum Spin Hall Effect in Graphene Nanoribbons via Edge Functionalization
Gabriel Autès, Oleg V. Yazyev
Kane and Mele predicted that in presence of spin-orbit interaction graphene realizes the quantum spin Hall state. However, exceptionally weak intrinsic spin-orbit splitting in grap…
Controlling edge states in the Kane-Mele model via edge chirality
Gabriel Autès, Oleg V. Yazyev
We investigate the dependence of band dispersion of the quantum spin Hall effect (QSHE) edge states in the Kane-Mele model on crystallographic orientation of the edges. Band struct…
New mechanism for generating spin transfer torque without charge current
G. Autès, J. Mathon, A. Umerski
A new physical mechanism for generating spin-transfer torque is proposed. It is due to interference of bias driven nonequilibrium electrons incident on a switching junction with th…
Giant Anisotropic Magneto-Resistance in ferromagnetic atomic contacts
M. Viret, M. Gabureac, F. Ott +3
Magneto-resistance is a physical effect of great fundamental and industrial interest since it is the basis for the magnetic field sensors used in computer read-heads and Magnetic R…
