Multiconfigurational time-dependent density functional theory for atomic nuclei: Technical and numerical aspects
Petar Marević, David Regnier, Denis Lacroix
The nuclear time-dependent density functional theory (TDDFT) is a tool of choice for describing various dynamical phenomena in atomic nuclei. In a recent study, we reported an exte…
Quantum fluctuations induce collective multiphonons in finite Fermi liquids
Petar Marević, David Regnier, Denis Lacroix
We show that collective multiphonon states in atomic nuclei emerge at high excitation energies when quantum fluctuations in the collective space are included beyond the independent…
Building Surrogate Models of Nuclear Density Functional Theory with Gaussian Processesand Autoencoders
Marc Verriere, Nicolas Schunck, Irene Kim +5
From the lightest Hydrogen isotopes up to the recently synthesized Oganesson (Z=118), it is estimated that as many as about 3000 atomic nuclei could exist in nature. Most of these…
Taming nuclear complexity with a committee of multilayer neural networks
R. -D. Lasseri, D. Regnier, J. -P. Ebran +1
We demonstrate that a committee of deep neural networks is capable of predicting the ground-state and excited energies of more than 1800 atomic nuclei with an accuracy akin to the…
