Automatic, high-order, and adaptive algorithms for Brillouin zone integration
Jason Kaye, Sophie Beck, Alex Barnett +2
We present efficient methods for Brillouin zone integration with a non-zero but possibly very small broadening factor , focusing on cases in which downfolded Hamiltonians can be…
Eliminating artificial boundary conditions in time-dependent density functional theory using Fourier contour deformation
Jason Kaye, Alex Barnett, Leslie Greengard +2
We present an efficient method for propagating the time-dependent Kohn-Sham equations in free space, based on the recently introduced Fourier contour deformation (FCD) approach. Fo…
Learning Feynman Diagrams with Tensor Trains
Yuriel Nunez-Fernandez, Matthieu Jeannin, Philipp T. Dumitrescu +4
We use tensor network techniques to obtain high order perturbative diagrammatic expansions for the quantum many-body problem at very high precision. The approach is based on a tens…
