Real-Space Approach to Light-Induced Hall Transport in Disordered Materials
Jorge Martinez Romeral, Luis M. Canonico, Aron W. Cummings +1
We introduce a linear-scaling real-space methodology to compute time-resolved electrical responses of materials driven far from equilibrium, with energy relaxation and disorder tre…
Real-Time Out-of-Equilibrium Quantum Dynamics in Disordered Materials
Luis M. Canonico, Stephan Roche, Aron W. Cummings
We report a linear-scaling numerical method for exploring nonequilibrium electron dynamics in systems of arbitrary complexity. Based on the Chebyshev expansion of the time evolutio…
Quantum transport in nitrogen-doped nanoporous graphenes
Gaetano Calogero, Isaac Alcón, Alan E. Anaya Morales +6
Bottom-up on-surface synthesized nanoporous graphenes (NPGs), realized as 2D arrays of laterally covalently bonded -conjugated graphene nanoribbons (GNRs), are a family of carb…
Proximity Effects Between the Graphene Quasicrystal and Magic-Angle Twisted Bilayer Graphene
Pedro Alcázar Guerrero, Viet-Hung Nguyen, Aron W. Cummings +2
We present a numerical study of three-layer graphene heterostructures in which the layers are twisted by the magic angle (1.1) or by to form a graphe…
Spin Polarization driven by Itinerant Orbital Angular Momentum in van der Waals Heterostructures
Luis M. Canonico, Jose H. GarcÃa, Aron W. Cummings +1
We report on the possibility of manipulating magnetic materials by using itinerant orbital angular momentum to produce out-of-plane spin polarization in van der Waals heterostructu…
Scaling of the Integrated Quantum Metric in Disordered Topological Phases
Jorge MartÃnez Romeral, Aron W. Cummings, Stephan Roche
We report a study of a disorder-dependent real-space representation of the quantum geometry in topological systems. Thanks to the development of an efficient linear-scaling numeric…
