The fate of quasiparticles at high-temperature
A. Hunter, S. Beck, E. Cappelli +17
We study the temperature evolution of quasiparticles in the correlated metal SrRuO. Our angle resolved photoemission data show that quasiparticles persist up to temperature…
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…
On nuclear short-range correlations and the zero-energy eigenstates of the Schrodinger equation
Saar Beck, Ronen Weiss, Nir Barnea
We present a systematic analysis of the nuclear 2 and 3-body short range correlations, and their relations to the zero-energy eigenstates of the Schrodinger equation. To this end w…
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…
