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…
Markov Inequality as a Tool for Linear-Scaling Estimation of Local Observables
H. P. Veiga, D. R. Pinheiro, J. P. Santos Pires +1
We introduce a linear-scaling stochastic method to compute real-space maps of any positive local spectral operator in a tight-binding model. By employing positive-definite estimato…
Semiconductor Wannier equations: a real-time, real-space approach to the nonlinear optical response in crystals (ATATA)
Eduardo B. Molinero, Bruno Amorim, Misha Ivanov +6
We develop the semiconductor Wannier equations (SWEs), a real-time, real-space formulation of ultrafast light-matter dynamics in crystals, by deriving the equations of motion for t…
