First principles calculations of electric-field-driven topological phase transitions in silicene, germanene and stanene
Julián Antonio Villarreal Murúa, Pablo Roura-Bas, Javier Daniel Fuhr +1
The emergence of two-dimensional topological materials, particularly the group-14 monolayers known as silicene, germanene, and stanene has opened promising pathways for next-genera…
Fermi sea topology and boundary geometry for free particles in one- and two-dimensional lattices
Guillermo R. Zemba
Free gasses of spinless fermions moving on a lattice-symmetric geometric background are considered. Their topological properties at zero temperature can be used to classify their F…
Charge and spin transport in nanoscopic structures with spin-orbit coupling
A. A. Reynoso, G. Usaj, C. A. Balseiro
During the last years there has been much interest, and theoretical discussion, about the possibility to use spin-orbit coupling to control the carriers spins in two-dimensional se…
Parallel spin transport and holonomy in non-Euclidean curved circuits on a spherical two-dimensional electron gas
E. J. Rodríguez, A. A. Reynoso, J. P. Baltanás +2
The quantum conductance of one-dimensional (1D) circuits built on flat (Euclidean) two-dimensional electron gases (2DEGs) is known to display a symmetric response to the inversion…
Electronic and magnetic properties of graphene-fluorographene nanoribbons: Controllable semiconductor-metal transition
R. M. Guzmán-Arellano, A. D. Hernández-Nieves, F. M. Peeters +1
We investigate the electronic and magnetic properties of graphene channels (--~nm wide) embedded within fluorographene, focusing on two distinct interfaces: the fully fluorin…
Effect of memristorś potentiation-depression curves peculiarities in the convergence of physical perceptrons
Walter Quiñonez, María José Sánchez, Diego Rubi
Neuromorphic computing aims to emulate the architecture and information processing mechanisms of the mammalian brain. This includes the implementation by hardware of neural network…
