Separable character of ab initio No-Core Shell Model one-body densities
J. Foy, Ch. Elster, P. Maris +2
Motivated by recent findings on the separability of optical potentials that are derived from folding off-shell densities with off-shell nucleon-nucleon amplitudes, we study the off…
Chiral uncertainties in ab initio nucleon-nucleus elastic scattering
R. B. Baker, M. Burrows, Ch. Elster +4
The effective interaction between a nucleon and a nucleus is one of the most important ingredients for reaction theories. Theoretical formulations were introduced early by Feshbach…
Ab initio folding potentials for proton-nucleus scattering with NCSM nonlocal one-body densities
Ch. Elster, M. Burrows, S. P. Weppner +3
Based on the spectator expansion of the multiple scattering series we employ a nonlocal translationally invariant nuclear density derived from a chiral next-to-next-to-leading orde…
Ab initio Folding Potentials for Nucleon-Nucleus Scattering based on NCSM One-Body Densities
M. Burrows, Ch. Elster, S. P. Weppner +4
Calculating microscopic optical potentials for elastic nucleon-nucleus scattering has already led to large body of work in the past. For folding first-order calculations the nucleo…
Ab initio Translationally Invariant Nonlocal One-body Densities from No-core Shell-model Theory
M. Burrows, Ch. Elster, G. Popa +3
[Background:] It is well known that effective nuclear interactions are in general nonlocal. Thus if nuclear densities obtained from {\it ab initio} no-core-shell-model (NCSM) calcu…
Non-Perturbative Calculation of the Scalar Yukawa Theory in Four-Body Truncation
Yang Li, V. A. Karmanov, P. Maris +1
The quenched scalar Yukawa theory is solved in the light-front Tamm-Dancoff approach including up to four constituents (one scalar nucleon, three scalar pions). The Fock sector dep…
Manifestation of three-body forces in three-body Bethe-Salpeter and light-front equations
V. A. Karmanov, P. Maris
Bethe-Salpeter and light-front bound state equations for three scalar particles interacting by scalar exchange-bosons are solved in ladder truncation. In contrast to two-body syste…
