Nonlinear Light Absorption in Many-Electron Systems Excited by an Instantaneous Electric Field: A Non-Perturbative Approach
Alberto Guandalini, Caterina Cocchi, Stefano Pittalis +2
We study light absorption in many-electron interacting systems beyond the linear regime by using a {\em single} broadband impulse of an electric field in the instantaneous limit. W…
Anisotropy and Size Effects on the Optical Spectra of Polycyclic Aromatic Hydrocarbons
Caterina Cocchi, Deborah Prezzi, Alice Ruini +2
The electronic and optical properties of polycyclic aromatic hydrocarbons (PAHs) present a strong dependence on their size and geometry. We tackle this issue by analyzing the spect…
Ab initio Simulation of Optical Limiting: The Case of Metal-Free Phthalocyanine
Caterina Cocchi, Deborah Prezzi, Alice Ruini +2
We present a fully ab initio, non-perturbative description of the optical limiting properties of a metal-free phthalocyanine, by simulating the effects of a broadband electric fiel…
Concavity Effects on the Optical Properties of Aromatic Hydrocarbons
Caterina Cocchi, Deborah Prezzi, Alice Ruini +3
We study the modifications on the ground and excited state properties of polycyclic aromatic hydrocarbons (PAHs), induced by the variation of concavity and -connectivity. Inspir…
Electronics and Optics of Graphene Nanoflakes: Edge Functionalization and Structural Distortions
Caterina Cocchi, Deborah Prezzi, Alice Ruini +2
The effects of edge covalent functionalization on the structural, electronic and optical properties of elongated armchair graphene nanoflakes (AGNFs) are analyzed in detail for a w…
Designing all-graphene nanojunctions by covalent functionalization
Caterina Cocchi, Alice Ruini, Deborah Prezzi +2
We investigated theoretically the effect of covalent edge functionalization, with organic functional groups, on the electronic properties of graphene nanostructures and nano-juncti…
