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…

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…
