Cloud Quantum Computing of an Atomic Nucleus
E. F. Dumitrescu, A. J. McCaskey, G. Hagen +6
We report a quantum simulation of the deuteron binding energy on quantum processors accessed via cloud servers. We use a Hamiltonian from pionless effective field theory at leading…
Optical potential from first principles
J. Rotureau, P. Danielewicz, G. Hagen +2
We develop a method to construct a microscopic optical potential from chiral interactions for nucleon-nucleus scattering. The optical potential is constructed by combining the Gree…
Electric dipole polarizability from first principles calculations
M. Miorelli, S. Bacca, N. Barnea +4
The electric dipole polarizability quantifies the low-energy behaviour of the dipole strength and is related to critical observables such as the radii of the proton and neutron dis…
Unexpectedly large charge radii of neutron-rich calcium isotopes
R. F. Garcia Ruiz, M. L. Bissell, K. Blaum +19
Despite being a complex many-body system, the atomic nucleus exhibits simple structures for certain "magic" numbers of protons and neutrons. The calcium chain in particular is both…
Emergent properties of nuclei from ab initio coupled-cluster calculations
G. Hagen, M. Hjorth-Jensen, G. R. Jansen +1
Emergent properties such as nuclear saturation and deformation, and the effects on shell structure due to the proximity of the scattering continuum and particle decay channels are…
Ultraviolet extrapolations in finite oscillator bases
S. König, S. K. Bogner, R. J. Furnstahl +2
The use of finite harmonic oscillator spaces in many-body calculations introduces both infrared (IR) and ultraviolet (UV) errors. The IR effects are well approximated by imposing a…
