Active-subspace learning reveals dominant parameter directions in nuclear observables
Tom Plies, Margarida Companys Franzke, Achim Schwenk
Nuclear observables computed using ab initio methods can depend on many low-energy constants (LECs) of the underlying chiral effective field theory interactions, while being sensit…
Hartree-Fock emulators for nuclei: Application to charge radii of Ca
Margarida Companys Franzke, Alexander Tichai, Kai Hebeler +1
Understanding the emergence of complex structures of nuclei from chiral effective field theory (EFT) is a central challenge. The large number of low-energy couplings (LECs) in the…
Eigenvector continuation for the pairing Hamiltonian
Margarida Companys Franzke, Alexander Tichai, Kai Hebeler +1
The development of emulators for the evaluation of many-body observables has gained increasing attention over the last years. In particular the framework of eigenvector continuatio…
Excited states from eigenvector continuation: the anharmonic oscillator
Margarida Companys Franzke, Alexander Tichai, Kai Hebeler +1
Eigenvector continuation (EC) has recently attracted a lot attention in nuclear structure and reactions as a variational resummation tool for many-body expansions. While previous a…
