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…
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…
Scaling of the Integrated Quantum Metric in Disordered Topological Phases
Jorge Martínez 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…
Orbital Hall Responses in Disordered Topological Materials
Luis M. Canonico, Jose H. García, Stephan Roche
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…
