Spin Polarization driven by Itinerant Orbital Angular Momentum in van der Waals Heterostructures
Luis M. Canonico, Jose H. García, 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…
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 carbo…
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…
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…
Upper limit of spin relaxation in suspended graphene
Aron W. Cummings, Simon M. -M. Dubois, Pedro Alcázar Guerrero +2
We use a combination of molecular dynamics and quantum transport simulations to investigate the upper limit of spin transport in suspended graphene. We find that thermally-induced…
Robust quantum engineering of current flow in carbon nanostructures at room temperature
Gaetano Calogero, Isaac Alcón, Onurcan Kaya +4
Bottom-up on-surface synthesis enables the fabrication of carbon nanostructures with atomic precision. Good examples are graphene nanoribbons (GNRs), 1D conjugated polymers, and na…

We report an efficient numerical approach to compute the different components of the orbital Hall responses in disordered topological materials from the Berry phase theory of magne…
Disorder-Induced Delocalization in Magic-Angle Twisted Bilayer Graphene
Pedro Alcázar Guerrero, Viet-Hung Nguyen, Jorge Martínez Romeral +4
Flat bands in moiré systems are exciting new playgrounds for the generation and study of exotic many-body physics phenomena in low-dimensional materials. Such physics is attributed…
Resilient Intraparticle Entanglement and its Manifestation in Spin Dynamics of Disordered Dirac Materials
Jorge Martinez Romeral, Aron W. Cummings, Stephan Roche
Topological quantum matter exhibits novel transport phenomena driven by entanglement between internal degrees of freedom, as for instance generated by spin-orbit coupling effects.…
Spin precession in anisotropic media
B. Raes, A. W. Cummings, F. Bonell +4
We generalize the diffusive model for spin injection and detection in nonlocal spin structures to account for spin precession under an applied magnetic field in an anisotropic medi…
