Persistent State Method for Resonances on Classical and Quantum Computers
Cong-Wu Wang, Lukas Bovermann, Evgeny Epelbaum +4
We introduce a new method for extracting resonance pole positions that does not require non-Hermitian extensions of a Hamiltonian. The complex resonance poles are extracted from un…
Non-perturbative three-nucleon simulation using chiral lattice EFT
Lukas Bovermann, Evgeny Epelbaum, Hermann Krebs +1
We study the three-nucleon system at next-to-next-to-next-to-leading order () in the framework of chiral effective field theory (EFT) on the lattice. Our calculatio…
Wavefunction matching for solving quantum many-body problems
Serdar Elhatisari, Lukas Bovermann, Yuanzhuo Ma +15
Ab initio calculations play an essential role in our fundamental understanding of quantum many-body systems across many subfields, from strongly correlated fermions to quantum chem…
Scattering phase shifts and mixing angles for an arbitrary number of coupled channels on the lattice
Lukas Bovermann, Evgeny Epelbaum, Hermann Krebs +1
We present a lattice method for determining scattering phase shifts and mixing angles for the case of an arbitrary number of coupled channels. Previous nuclear lattice effective fi…
