HIGHLIGHTS
- who: Sparse sampling et al. from the Department of Solid State Physics, TU Wien, Vienna, Austria Department of Physics, Saitama University, Saitama, Japan have published the paper: (2023) Original software publication sparse-ir: Optimal compression and of many-body propagators, in the Journal: (JOURNAL) of 28/06/2022
SUMMARY
The intermediate representation (IR) instead leverages the analytical structure of imaginary-time propagators to construct a maximally compact, orthonormal basis: the number of basis functions needed to represent a propagator scales logarithmically with the desired accuracy and logarithmically with Λ, the ultraviolet cutoff in units . . .
