Combining phase-space and time-dependent reduced density matrix approach to describe the dynamics of interacting fermions
Thomas Czuba, Denis Lacroix, David Regnier +2
The possibility to apply phase-space methods to many-body interacting systems might provide accurate descriptions of correlations with a reduced numerical cost. For instance, the s…
Low-density in-medium effects on light clusters from heavy-ion data
Helena Pais, Rémi Bougault, Francesca Gulminelli +13
The modification of the ground state properties of light atomic nuclei in the nuclear and stellar medium is addressed, using chemical equilibrium constants evaluated from a new ana…
Spectroscopy of short-lived radioactive molecules: A sensitive laboratory for new physics
R. F. Garcia Ruiz, R. Berger, J. Billowes +24
The study of molecular systems provides exceptional opportunities for the exploration of the fundamental laws of nature and for the search for physics beyond the Standard Model of…
Mean-Field Theory for Fermion Pairs and the ab initio Particle-Vibration-Coupling Approach
Peter Schuck
A Dyson Bethe-Salpeter equation (Dyson-BSE) for fermion pairs is presented whose kernel has a static and a one frequency dependent contribution, analogous to the self energy of the…
Comparison of cuprates and nuclear matter pairing properties. Quartet (alpha-particle) condensation in nuclear systems
P. Schuck
A comparison of pairing properties in cuprates and nuclear matter is briefly discussed. Quartet (alpha-particle) condensation is a very important aspect of nuclear physics. The phy…
Energy-density functionals inspired by effective-field theories: Applications to neutron drops
Jérémy Bonnard, Marcella Grasso, Denis Lacroix
New energy-density functionals (EDFs) inspired by effective-field theories (EFTs) have been recently proposed. The present work focuses on three of such functionals which were deve…
Long-wavelength phonons in the crystalline and pasta phases of neutron-star crusts
David Durel, Michael Urban
We study the long-wavelength excitations of the inner crust of neutron stars, considering three phases: cubic crystal at low densities, rods and plates near the core-crust transiti…
A Lee-Yang--inspired functional with a density--dependent neutron-neutron scattering length
M. Grasso, D. Lacroix, C. J. Yang
Inspired by the low--density Lee-Yang expansion for the energy of a dilute Fermi gas of density and momentum , we introduce here a Skyrme--type functional that contains on…
From bare interactions, low--energy constants and unitary gas to nuclear density functionals without free parameters: application to neutron matter
Denis Lacroix, Antoine Boulet, Marcella Grasso +1
We further progress along the line of Ref. [Phys. Rev. {\bf A 94}, 043614 (2016)] where a functional for Fermi systems with anomalously large -wave scattering length was p…
Octet baryon masses and sigma terms in covariant baryon chiral perturbation theory
Xiu-Lei Ren, Li-Sheng Geng, Jie Meng
We report on a recent study of the ground-state octet baryon masses and sigma terms in covariant baryon chiral perturbation theory with the extended-on-mass-shell scheme up to next…
Bound state techniques to solve the multiparticle scattering problem
J. Carbonell, A. Deltuva, A. C. Fonseca +1
Solution of the scattering problem turns to be very difficult task both from the formal as well as from the computational point of view. If the last two decades have witnessed deci…
Alpha-Particle Clustering from Expanding Self-Conjugate Nuclei within the Hartree-Fock-Bogoliubov Approach
Michel Girod, Peter Schuck
The nuclear equation of state is explored with the constrained HFB approach for self conjugate nuclei. It is found that beyond a certain low, more or less universal density, those…
Self-Consistent RPA from a Coupled Cluster Wave Function Perspective
M. Jemai, D. S. Delion, P. Schuck
Self-Consistent RPA is rederived in a consistent way with the help of the Coupled Cluster ground state wave function truncated at the two body level. An exact killing operator for…
Complex scaling method for three- and four-body scattering above the break-up thresholds
Rimantas Lazauskas, Jaume Carbonell
A formalism based on the complex-scaling method is presented to solve the few particle scattering problem in configuration space using bound state techniques with trivial boundary…
Spin Scissors Mode and the Fine Structure of M1 States in Nuclei
E. B. Balbutsev, I. V. Molodtsova, P. Schuck
The coupled dynamics of low lying modes, including the scissors mode, and various giant quadrupole resonances are studied with the help of the Wigner Function Moments method genera…
Self-Consistent RPA based on a Many-Body Vacuum
Mohsen Jemai, Peter Schuck
Self-Consistent RPA is extended in a way so that it is compatable with a variational ansatz for the ground state wave function as a fermionic many-body vacuum. Employing the usual…
Role of non-collective excitations in low-energy heavy-ion reactions
S. Yusa, K. Hagino, N. Rowley
We investigate the effect of single-particle excitations on heavy-ion reactions at energies near the Coulomb barrier. To this end, we describe single-particle degrees of freedom wi…

E. B. Balbutsev, P. Schuck
Three methods to describe collective motion, Random Phase Approximation (RPA), Wigner Function Moments (WFM) and the Green's Function (GF) method are compared in detail and their p…
