Elastic deuteron-deuteron scattering in the channel within Nuclear Lattice Effective Field Theory
Helen Meyer, Serdar Elhatisari, Fabian Hildenbrand +1
We calculate low-energy deuteron-deuteron scattering in the spin-quintet channel using nuclear lattice effective field theory. The calculation combines chiral interaction…
Lattice calculation of the Sn isotopes near the proton dripline
Fabian Hildenbrand, Serdar Elhatisari, Ulf-G. Meißner +4
We present the first lattice calculations of the proton-rich tin isotopes Sn to Sn using nuclear lattice effective field theory with high-fideli…
Ab initio lattice study of neutron-alpha scattering with chiral forces at N3LO
Serdar Elhatisari, Fabian Hildenbrand, Ulf-G. Meißner
We present the first ab initio lattice calculation of neutron-alpha (-) scattering using nuclear lattice effective field theory (NLEFT) with chiral interactions at next-to-ne…
The triton lifetime from nuclear lattice effective field theory
Serdar Elhatisari, Fabian Hildenbrand, Ulf-G. Meißner
In this work, we present a calculation of the triton -decay lifetime using Nuclear Lattice Effective Field Theory (NLEFT) at next-to-next-to-next-to-leading order in the chiral…
Towards Hypernuclei from Nuclear Lattice Effective Field Theory
Fabian Hildenbrand, Serdar Elhatisari, Zhengxue Ren +1
Understanding the strong interactions within baryonic systems beyond the up and down quark sector is pivotal for a comprehensive description of nuclear forces. This study explores…
Pionic Final State Interactions and the Hypertriton Lifetime
Fabian Hildenbrand, Hans-Werner Hammer
We analyze the contribution of pionic final state interactions (FSI) in the weak decay of the hypertriton. Focusing on the He channel, we find a contribution of the pionic FSI…
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…
Lattice Monte Carlo Simulations with Two Impurity Worldlines
Fabian Hildenbrand, Serdar Elhatisari, Timo A. Lähde +2
We develop the impurity lattice Monte Carlo formalism, for the case of two distinguishable impurities in a bath of polarized fermions. The majority particles are treated as explici…
Lifetime of the hypertriton
F. Hildenbrand, H. -W. Hammer
We calculate the lifetime of the hypertriton as function of the separation energy in an effective field theory with and deuteron degrees of freedom. We also consider…
Three-Body Hypernuclei in Pionless Effective Field Theory
F. Hildenbrand, H. -W. Hammer
We calculate the structure of three-body hypernuclei with using pionless effective field theory at leading order in the isospin and sectors. In both sectors, thr…
