Efficient Time-Domain Approach for Linear Response Functions
Michel Panhans, Frank Ortmann
We derive the general Kubo formula in a form that solely utilizes the time evolution of displacement operators. The derivation is based on the decomposition of the linear response…
Linear Scaling Quantum Transport Methodologies
Zheyong Fan, Jose Hugo Garcia, Aron W. Cummings +5
In recent years, predictive computational modeling has become a cornerstone for the study of fundamental electronic, optical, and thermal properties in complex forms of condensed m…
Pseudospin-driven spin relaxation mechanism in graphene
Dinh Van Tuan, Frank Ortmann, David Soriano +2
The possibility of transporting spin information over long distances in graphene, owing to its small intrinsic spin-orbit coupling (SOC) and the absence of hyperfine interaction, h…
Unconventional Features in the Quantum Hall Regime of Disordered Graphene: Percolating Impurity States and Hall Conductance Quantization
Nicolas Leconte, Frank Ortmann, Alessandro Cresti +1
We report on the formation of critical states in disordered graphene, at the origin of variable and unconventional transport properties in the quantum Hall regime, such as a zero-e…
Spin Dynamics and Relaxation in Graphene Dictated by Electron-hole Puddles
Dinh Van Tuan, Frank Ortmann, Aron W. Cummings +2
The understanding of spin dynamics and relaxation mechanisms in clean graphene and the upper time and length scales on which spin devices can operate are prerequisites to realizing…
Spin Transport in Hydrogenated Graphene
David Soriano, Dinh Van Tuan, Simon M. -M. Dubois +7
In this review we discuss the multifaceted problem of spin transport in hydrogenated graphene from a theoretical perspective. The current experimental findings suggest that hydroge…
