What is ab initio in nuclear theory?
A. Ekström, C. Forssén, G. Hagen +3
Ab initio has been used as a label in nuclear theory for over two decades. Its meaning has evolved and broadened over the years. We present our interpretation, briefly review its h…
Towards Precise and Accurate Calculations of Neutrinoless Double-Beta Decay: Project Scoping Workshop Report
V. Cirigliano, Z. Davoudi, J. Engel +20
We present the results of a National Science Foundation (NSF) Project Scoping Workshop, the purpose of which was to assess the current status of calculations for the nuclear matrix…
How to renormalize coupled cluster theory
Z. H. Sun, C. A. Bell, G. Hagen +1
Coupled cluster theory is an attractive tool to solve the quantum many-body problem because its singles and doubles (CCSD) approximation is computationally affordable and yields ab…
Spectral function for He using the Chebyshev expansion in coupled-cluster theory
J. E. Sobczyk, S. Bacca, G. Hagen +1
We compute spectral function for He by combining coupled-cluster theory with an expansion of integral transforms into Chebyshev polynomials. Our method allows to estimate the u…
Quantum computing of the Li nucleus via ordered unitary coupled clusters
Oriel Kiss, Michele Grossi, Pavel Lougovski +3
The variational quantum eigensolver (VQE) is an algorithm to compute ground and excited state energy of quantum many-body systems. A key component of the algorithm and an active re…
Effective field theory of pairing rotations
T. Papenbrock
Pairing rotations are the low-energy excitations of finite superfluid systems, connecting systems that differ in their number of Cooper pairs. This paper presents a model-independe…
