Conductance quantization and transport gaps in disordered graphene nanoribbons
We study numerically the effects of edge and bulk disorder on the conductance of graphene nanoribbons. We compute the conductance suppression due to Anderson localization induced by edge scatteringExpand

Measuring the Lyapunov exponent using quantum mechanics.
We study the time evolution of two wave packets prepared at the same initial state, but evolving under slightly different Hamiltonians. For chaotic systems, we determine the circumstances that leadExpand

Numerical studies of conductivity and Fano factor in disordered graphene
Using the recursive Green's function method, we study the problem of electron transport in a disordered single-layer graphene sheet. The conductivity is of order ${e}^{2}∕h$ and its dependence on theExpand

Impurity invisibility in graphene: Symmetry guidelines for the design of efficient sensors
Renowned for its sensitivity to detect the presence of numerous substances, graphene is an excellent chemical sensor. Unfortunately, which general features a dopant must have in order to enter theExpand

Stochastic versus semiclassical approach to quantum chaotic scattering
Abstract We explore the universal features of quantum scattering systems for which the classical scattering is chaotic. We do so by comparing the semiclassical approach and the stochastic approach,Expand

The recursive Green’s function method for graphene
We describe how to apply the recursive Green’s function method to the computation of electronic transport properties of graphene sheets and nanoribbons in the linear response regime. This methodExpand

Strain-displacement relations for strain engineering in single-layer 2d materials
We investigate the electromechanical coupling in single-layer 2d materials. For non-Bravais lattices, we find important corrections to the standard macroscopic strain-microscopic atomic-displacementExpand

Particle-Spin Coupling in a Chaotic System: Localization-Delocalization in the Husimi Distributions
The wave functions of the Dicke Hamiltonian, describing a spin coupled to a bosonic mode, are studied via Husimi distributions. A classical analogue of this system is also obtained. For severalExpand

Effects of disorder range and electronic energy on the perfect transmission in graphene nanoribbons
Numerical calculations based on the recursive Green's functions method in the tight-binding approximation are performed to calculate the dimensionless conductance $g$ in disordered grapheneExpand
