Effects of gold cluster intercalation in graphene: stationary waves and modified QPI features
Cristina Bena, Marion Cranney, Poonam Kumari +2
Gold intercalation beneath epitaxial graphene on SiC produces a cluster phase with unusual standing waves and quasiparticle-interference (QPI) features concentrated near the graphe…

An iterative method bridging DFT, disorder averaging, and experiment in intercalated materials: application to Au-intercalated graphene
Poonam Kumari, Alberto Zobelli, Igor de Melo Froldi +3
Intercalation can strongly modify the electronic dispersion of a host material, as directly revealed by angle-resolved photoemission spectroscopy (ARPES). We develop a general iter…

Modelling spin-orbitronics effects at interfaces and chiral molecules
Poonam Kumari, Cyrille Barreteau, Alexander Smogunov
Using orbital angular momentum (OAM) currents in nanoelectronics, for example, for magnetization manipulation via spin-orbit torque (SOT), represents a growing field known as "spin…
