Multiscale space-time ansatz for correlation functions of quantum systems based on quantics tensor trains
Hiroshi Shinaoka, Markus Wallerberger, Yuta Murakami +4
Correlation functions of quantum systems -- central objects in quantum field theories -- are defined in high-dimensional space-time domains. Their numerical treatment thus suffers…
sparse-ir: optimal compression and sparse sampling of many-body propagators
Markus Wallerberger, Samuel Badr, Shintaro Hoshino +13
We introduce sparse-ir, a collection of libraries to efficiently handle imaginary-time propagators, a central object in finite-temperature quantum many-body calculations. We levera…
Even-odd parity transition in strongly correlated locally noncentrosymmetric superconductors : An application to CeRhAs
Kosuke Nogaki, Youichi Yanase
The discovery of the multiple - phase diagram of CeRhAs offers a new route to designing topological superconductors. Although weak-coupling theories explain the exper…
