Kinetic-energy dissipation and fluctuations in strongly damped heavy-ion collisions within the stochastic mean-field approach

Journal Article Ayik, Sakir ; Sekizawa, Kazuyuki - Physical Review. C

Microscopic mean-field approaches have been successful in describing the most probable reaction outcomes in low-energy heavy-ion reactions. However, those approaches are known to severely underestimate dispersions of observables around the average values that has limited their applicability. Recently it has been shown that a quantal transport approach based on the stochastic mean-field (SMF) theory significantly improves the description, while its application has been limited so far to fragment mass and charge dispersions. In this work, we extend the quantal transport approach based on the SMF theory for relative kinetic energy dissipation and angular momentum transfer in low-energy heavy-ion reactions.

Isospin-symmetry-breaking effects in A∼70 nuclei within beyond-mean-field approach

Journal Article Petrovici, A. ; Andrei, O. - AIP Conference Proceedings

Particular isospin-symmetry-breaking probes including Coulomb energy differences (CED), mirror energy differences (MED), and triplet energy differences (TED) manifest anomalies in the A∼70 isovector triplets of nuclei. The structure of proton-rich nuclei in the A∼70 mass region suggests shape coexistence and competition between pairing correlations in different channels. Recent results concerning the interplay between isospin-mixing and shape-coexistence effects on exotic phenomena in A∼70 nuclei obtained within the beyond-mean-field complex Excited Vampir variational model with symmetry projection before variation using a realistic effective interaction in a relatively large model space are presented. Excited Vampir predictions concerning the Gamow-Teller β decay to themore »« less

Nonequilibrium evolution of a {open_quotes}tsunami,{close_quotes} a high multiplicity initial quantum state: Dynamical symmetry breaking

Journal Article Boyanovsky, D ; de Vega, H J ; Holman, R ; ... - Physical Review, D

We propose to study the nonequilibrium features of heavy-ion collisions by following the evolution of an initial state with a large number of quanta with a distribution around a momentum {vert_bar}{rvec k}{sub 0}{vert_bar} corresponding to a {ital thin spherical shell} in momentum space, a {open_quotes}tsunami.{close_quotes} An O(N)({rvec {Phi}}{sup 2}){sup 2} model field theory in the large N limit is used as a framework to study the nonperturbative aspects of the nonequilibrium dynamics including a resummation of the effects of the medium (the initial particle distribution). In a theory where the symmetry is spontaneously broken in the absence of the medium,more »« less

Fluctuation and dissipation dynamics in fusion reactions from a stochastic mean-field approach

Journal Article Ayik, Sakir ; Washiyama, Kouhei ; Lacroix, Denis - Physical Review. C, Nuclear Physics

By projecting the stochastic mean-field dynamics on a suitable collective path during the entrance channel of heavy-ion collisions, expressions for transport coefficients associated with relative distance are extracted. These transport coefficients, which have forms similar to those familiar from the nucleon exchange model, are evaluated by carrying out time-dependent Hartree-Fock simulations. The calculations provide an accurate description of the magnitude and form factor of transport coefficients associated with one-body dissipation and fluctuation mechanisms.
