Cross-extrapolation reconstruction of low-rank functions and application to quantum many-body observables in the strong coupling regime
Matthieu Jeannin, Yuriel Núñez-Fernández, Thomas Kloss +2
We present a general-purpose algorithm to extrapolate a low rank function of two variables from a small domain to a larger one. It is based on the cross-interpolation formula. We a…
A Tensor Train Continuous Time Solver for Quantum Impurity Models
A. Erpenbeck, W. -T. Lin, T. Blommel +8
The simulation of strongly correlated quantum impurity models is a significant challenge in modern condensed matter physics that has multiple important applications. Thus far, the…
Determination of superexchange interactions for the CuO chains in LiCuO
N. Aucar Boidi, Christian Helman, Y. Núñez-Fernández +2
Starting from \textit{ab-initio} calculations, we derive a five-band Hubbard model to describe the CuO chains of LiCuO. This model is further simplified to a low-energy…
