The asymptotic behaviour of the many-body coupled cluster amplitudes
Saar Beck, Ronen Weiss, Nir Barnea
We analyze the asymptotic behaviour of the coupled cluster many-body wave-function in the limit of highly excited two- and three-particles states. We find that in this limit the di…

Removing the Wigner bound in non-perturbative effective field theory
Saar Beck, Betzalel Bazak, Nir Barnea
The Wigner bound, setting an upper limit on the scattering effective range, is examined at different orders of contact effective field theory. Using cutoff regulator we show that t…
