Recent advances in coupled cluster computations of open-shell atomic nuclei
Francesco Marino, Francesca Bonaiti, Sonia Bacca +5
In this contribution, we report on recent progress in coupled-cluster simulations of open-shell atomic nuclei using interactions consistently derived from chiral effective field th…
Mean-field approximation on steroids: exact description of the deuteron
B. Bally, A. Scalesi, V. Somà +2
The present article demonstrates that the deuteron, i.e. the lightest bound nuclear system made of a single proton and a single neutron, can be accurately described within a mean-f…
Dimensionality reduction through tensor factorization : application to \textit{ab initio} nuclear physics calculations
Mikael Frosini, Thomas Duguet, Pierre Tamagno +1
The construction of predictive models of atomic nuclei from first principles is a challenging (yet necessary) task towards the systematic generation of theoretical predictions (and…
Deformed natural orbitals for ab initio calculations
Alberto Scalesi, Thomas Duguet, Mikael Frosini +1
The rapid development of ab initio nuclear structure methods towards doubly open-shell nuclei, heavy nuclei and greater accuracy occurs at the price of evermore increased computati…
Ab initio Bogoliubov many-body perturbation theory: closed-form constraint on the average particle number
Pepijn Demol, Thomas Duguet, Alexander Tichai
Bogoliubov many-body perturbation theory (BMBPT) relying on the breaking of U(1) global gauge symmetry has been recently formulated and applied to extend the applicability of stand…
Ab initio description of monopole resonances in light- and medium-mass nuclei: IV. Angular momentum projection and rotation-vibration coupling
Andrea Porro, Thomas Duguet, Jean-Paul Ebran +3
Giant Resonances are, with nuclear rotations, the most evident expression of collectivity in finite nuclei. These two categories of excitations, however, are traditionally describe…
Impact of correlations on nuclear binding energies
Alberto Scalesi, Thomas Duguet, Pepijn Demol +3
A strong effort will be dedicated in the coming years to extend the reach of ab initio nuclear-structure calculations to heavy doubly open-shell nuclei. In order to do so, the most…
Anisotropic flow in fixed-target Pb+Ne collisions as a probe of quark-gluon plasma
Giuliano Giacalone, Wenbin Zhao, Benjamin Bally +19
The System for Measuring Overlap with Gas (SMOG2) at the LHCb detector enables the study of fixed-target ion-ion collisions at relativistic energies ( GeV…
Ab initio description of monopole resonances in light- and medium-mass nuclei: III. Moments evaluation in ab initio PGCM calculations
Andrea Porro, Thomas Duguet, Jean-Paul Ebran +3
The paper is the third of a series dedicated to the ab initio description of monopole giant resonances in mid-mass closed- and open-shell nuclei via the so-called projected generat…
Tensor factorization in ab initio many-body calculations: Triaxially-deformed (B) MBPT calculations in large bases
M. Frosini, T. Duguet, P. Tamagno
Whether for fundamental studies or nuclear data evaluations, first-principle calculations of atomic nuclei constitute the path forward. Today, performing \textit{ab initio} calcula…
Ab initio description of monopole resonances in light- and medium-mass nuclei: II. Ab initio PGCM calculations in Ti, Si and Mg
Andrea Porro, Thomas Duguet, Jean-Paul Ebran +3
Giant resonances (GRs) are a striking manifestation of collective motions in atomic nuclei. The present paper is the second in a series of four dedicated to the use of the projecte…
The unexpected uses of a bowling pin: exploiting Ne isotopes for precision characterizations of collectivity in small systems
Giuliano Giacalone, Benjamin Bally, Govert Nijs +16
Whether or not femto-scale droplets of quark-gluon plasma (QGP) are formed in so-called small systems at high-energy colliders is a pressing question in the phenomenology of the st…
Ab initio description of monopole resonances in light- and medium-mass nuclei: I. Technical aspects and uncertainties of ab initio PGCM calculations
Andrea Porro, Thomas Duguet, Jean-Paul Ebran +3
Giant resonances (GRs) are a striking manifestation of collective motions in mesoscopic systems such as atomic nuclei. Until recently, theoretical investigations have essentially r…
On the calculation and use of effective single-particle energies. The example of the neutron - splitting along isotones
Vittorio Somà, Thomas Duguet
The rich phenomenology of quantum many-body systems such as atomic nuclei is complex to interpret. Often, the behaviour (e.g. evolution with the number of constituents) of measurab…
