Nuclear charge radii of aluminium isotopes at the proton drip line
Alex Brinson, Brooke Rickey, Pierre Arthuis +35
Understanding the evolution of nuclear size away from stability remains a central challenge in nuclear physics. In neutron-deficient systems, charge radii can be highly sensitive t…
Many-body perturbation theory for the nuclear equation of state up to fifth order
C. Drischler, K. S. McElvain, P. Arthuis
We present an automated, GPU-accelerated framework for many-body perturbation theory (MBPT) calculations of the zero-temperature nuclear equation of state (EOS) based on chiral nuc…
First Extraction of the Matter Radius of Sn via Proton Elastic Scattering at 200 MeV/Nucleon
Y. Hijikata, J. Zenihiro, S. Terashima +34
The angular distribution of the differential cross sections for proton elastic scattering from Sn at 196-210 MeV/nucleon was successfully measured over a momentum transfer…
Connecting Relativistic Density Functional Theory to Microscopic Calculations
Brendan T. Reed, Matthias Heinz, Pierre Arthuis +2
The development of systematic effective field theories (EFTs) for nuclear forces and advances in solving the nuclear many-body problem have greatly improved our understanding of de…
Neutron-rich nuclei and neutron skins from chiral low-resolution interactions
P. Arthuis, K. Hebeler, A. Schwenk
Neutron-rich nuclei provide important insights to nuclear forces and to the nuclear equation of state. Advances in ab initio methods combined with new opportunities with rare isoto…
Randomized Low-Rank Decompositions of Nuclear Three-Body Interactions
A. Tichai, P. Arthuis, K. Hebeler +5
First-principles simulations of many-fermion systems are commonly limited by the computational requirements of processing large data objects. As a remedy, we propose the use of low…
Least-square approach for singular value decompositions of scattering problems
A. Tichai, P. Arthuis, K. Hebeler +4
It was recently observed that chiral two-body interactions can be efficiently represented using matrix factorization techniques such as the singular value decomposition. However, t…
Quantum Monte Carlo in Configuration Space with Three-Nucleon Forces
Pierre Arthuis, Carlo Barbieri, Francesco Pederiva +1
Neutron matter, through its connection to neutron stars as well as systems like cold atom gases, is one of the most interesting yet computationally accessible systems in nuclear ph…
Low-rank matrix decompositions for ab initio nuclear structure
A. Tichai, P. Arthuis, K. Hebeler +3
The extension of ab initio quantum many-body theory to higher accuracy and larger systems is intrinsically limited by the handling of large data objects in form of wave-function ex…
ADG: Automated generation and evaluation of many-body diagrams III. Bogoliubov in-medium similarity renormalization group formalism
A. Tichai, P. Arthuis, H. Hergert +1
The goal of the present paper is twofold. First, a novel expansion many-body method applicable to superfluid open-shell nuclei, the so-called Bogoliubov in-medium similarity renorm…
ADG: Automated generation and evaluation of many-body diagrams II. Particle-number projected Bogoliubov many-body perturbation theory
P. Arthuis, A. Tichai, J. Ripoche +1
We describe the second version (v2.0.0) of the code ADG that automatically (1) generates all valid off-diagonal Bogoliubov many-body perturbation theory diagrams at play in particl…
Ab initio computation of charge densities for Sn and Xe isotopes
P. Arthuis, C. Barbieri, M. Vorabbi +1
We present the first ab initio calculations for open-shell nuclei past the tin isotopic line, focusing on Xe isotopes as well as doubly-magic Sn isotopes. We show that, even for mo…
ADG: Automated generation and evaluation of many-body diagrams I. Bogoliubov many-body perturbation theory
Pierre Arthuis, Thomas Duguet, Alexander Tichai +2
We describe the first version (v1.0.0) of the code ADG that automatically (1) generates all valid Bogoliubov many-body perturbation theory (BMBPT) diagrams and (2) evaluates their…
Bogoliubov Many-Body Perturbation Theory for Open-Shell Nuclei
Alexander Tichai, Pierre Arthuis, Thomas Duguet +3
A novel Rayleigh-Schrödinger many-body perturbation theory (MBPT) approach is introduced by making use of a particle-number-breaking Bogoliubov reference state to tackle (near-)deg…
