Linear Scaling Approach for Optical Excitations Using Maximally Localized Wannier Functions

We present a theoretical method for calculating optical absorption spectra based on maximally localized Wannier functions, which is suitable for large periodic systems. For this purpose, we calculate the exciton Hamiltonian, which determines the Beth

Linear scaling approach for atomistic calculation of excitonic properties of 10-million-atom nanostructures

Autor: Różański, Piotr T., Zieliński, Michał

Numerical calculations of excitonic properties of novel nanostructures, such as nanowire and crystal phase quantum dots, must combine atomistic accuracy with an approachable computational complexity. The key difficulty comes from the fact that excito

Efficient Linear Scaling Approach for Computing the Kubo Hall Conductivity

Autor: Ortmann, Frank, Leconte, Nicolas, Roche, Stephan

We report an order-N approach to compute the Kubo Hall conductivity for disorderd two-dimensional systems reaching tens of millions of orbitals, and realistic values of the applied external magnetic fields (as low as a few Tesla). A time-evolution sc

Biorthogonal linear-scaling approach for the transcorrelated method

Autor: Kojo, Masashi, Hirose, Kikuji

We develop a biorthogonal linear-scaling algorithm for a transcorrelated method based on the localized nature of transformed orbitals. The transcorrelated method, which employs a similarity-transformed Hamiltonian referred to as a transcorrelated Ham
