Comparison of renormalized interactions using one-dimensional few-body systems as a testbed
Fabian Brauneis, Hans-Werner Hammer, Stephanie M. Reimann +1
Even though the one-dimensional contact interaction requires no regularization, renormalization methods have been shown to improve the convergence of numerical ab initio calculatio…

Range Corrections to Doublet S-Wave Neutron-Deuteron Scattering
H. -W. Hammer, Thomas Mehen
We calculate the range corrections to S-wave neutron-deuteron scattering in the doublet channel (S=1/2) to first order in r/a where a is the scattering length and r the effective r…

A renormalized equation for the three-body system with short-range interactions
H. -W. Hammer, Thomas Mehen
We study the three-body system with short-range interactions characterized by an unnaturally large two-body scattering length. We show that the off-shell scattering amplitude is cu…
