Real-Space Spectral Approach to Orbital Magnetization
Kevin J. U. Vidarte, Henrique P. Veiga, João M. Viana Parente Lopes +4
We present a real-space spectral method for computing the orbital magnetization of crystals. Starting from the commutator form of the orbital magnetization operator, we formulate a…
Plasmon polariton assisted second-harmonic generation in graphene
João M. Alendouro Pinho, Simão S. Cardoso, Yuliy V. Bludov +4
In this paper we present a theoretical examination of second-harmonic generation (SHG) in a graphene monolayer integrated within an attenuated total internal reflection (ATR) confi…
Unambiguous Simulation of Diffusive Charge Transport in Disordered Nanoribbons
H. P. Veiga, S. M. João, J. M. Alendouro Pinho +2
Charge transport in disordered two-dimensional (2D) systems showcases a myriad of unique phenomenologies that highlight different aspects of the underlying quantum dynamics. Electr…
Fast Fourier-Chebyshev approach to real-space simulations of the Kubo formula
Santiago Giménez de Castro, João M. Viana Parente Lopes, Aires Ferreira +1
The Kubo formula is a cornerstone in our understanding of near-equilibrium transport phenomena. While conceptually elegant, the application of Kubo's linear-response theory to inte…
