Silicene nanoribbons on an insulating thin film
Khalid Quertite, Hanna Enriquez, Nicolas Trcera +10
Silicene, a new two-dimensional (2D) material has attracted intense research because of the ubiquitous use of silicon in modern technology. However, producing free-standing silicen…
Weakly interacting disordered Bose gases out of equilibrium: from multiple scattering to superfluidity
Thibault Scoquart, Pierre-Élie Larré, Dominique Delande +1
We explore the quench dynamics of a two-dimensional, weakly interacting disordered Bose gas for various relative strengths of interactions and disorder. This allows us to identify…
Heterostrain rules the flat-bands in magic-angle twisted graphene layers
F. Mesple, A. Missaoui, T. Cea +5
The moiré of twisted graphene bilayers can generate flat bands in which charge carriers do not posses enough kinetic energy to escape Coulomb interactions with each other leading t…
Triple point fermions in ferroelectric GeTe
Juraj Krempaský, Laurent Nicolaï, Martin Gmitra +10
Ferroelectric GeTe is unveiled to exhibit an intriguing multiple non-trivial topology of the electronic band structure due to the existence of triple-point and type-II Weyl fermion…
Edge magnetic properties of black phosphorene nanoribbons
Javad Vahedi, Robert Peters
The magnetic properties of black phosphorene nanoribbons are investigated using static and dynamical mean-field theory. Besides confirming the existence of ferromagnetic/antiferrom…
Fermiology and electron-phonon coupling in the 2H and 3R polytypes of NbS
Zakariae El Youbi, Sung Won Jung, Christine Richter +3
We investigate the electronic structure of the 2H and 3R polytypes of NbS. The Fermi surfaces measured by angle-resolved photoemission spectroscopy show a remarkable difference…
