The Skyrme effective interaction, with its multitude of parameterisations, along implemen- tation using the static and time-dependent density functional (TDHF) formalism have allowed for a range microscopic calculations low-energy heavy-ion collisions. These allow variation interaction an interpretation results this informed by comparison to experimental data. Initial progress in implementing TDHF collisions necessarily used many approximations geometry or interaction. Over last decade so,...
Background: It is generally acknowledged that the time-dependent Hartree--Fock (TDHF) method provides a useful foundation for fully microscopic many-body theory of low-energy heavy ion reactions. The TDHF also known in nuclear physics small-amplitude domain, where it description collective states, and based on mean-field formalism, which has been relatively successful approximation to problem. Currently, being widely used study fusion excitation functions, fission, deep-inelastic scattering...
We present results of collisions $^{90}$Zr+$^{90}$Zr and $^{96}$Zr+$^{96}$Zr obtained within time-dependent density functional theory (TDDFT) extended to superfluid systems, known as local approximation (TDSLDA). discuss qualitatively new features occurring in two nuclei at energies the vicinity Coulomb barrier. show that a \textit{solitonic excitation} -- an abrupt pairing phase distortion reported previously [P.~Magierski et al., Phys. Rev. Lett. \textbf{119}, 042501 (2017)], increases...
Abstract The function of long calling is a subject interest across animal behaviour study, particularly within primatology. Many primate species have male‐specific long‐distance calls, including platyrrhines like the folivorous howler monkey ( Alouatta spp.). Howler monkeys may howl to defend resources such as feeding trees or areas rich vegetation from other groups. This study tests ecological resource defence hypothesis for howling in mantled palliata ) and investigates how anthropogenic...
Friction coefficients for the fusion reaction $^{16}\mathrm{O}+^{16}\mathrm{O}\ensuremath{\rightarrow}^{32}\mathrm{S}$ are extracted based on both time-dependent Hartree-Fock and density matrix methods. The latter goes beyond mean-field approximation by taking into account effect of two-body correlations, but in practical simulations reactions we find that total energy is not conserved. We analyze this problem propose a solution allows clear quantification dissipative effects dynamics....
Background: Time-dependent techniques in nuclear theory often rely on mean-field or Hartree-Fock descriptions. Beyond-mean-field dynamical calculations within the time-dependent density matrix (TDDM) have invoked symmetry restrictions and ignored connection between mean field induced interaction.Purpose: We study ground states obtained a TDDM approach for nuclei from $A=12$ to $A=24$, including examples of even-even odd-even with without intrinsic deformation. overcome previous limitations...
Superfluidity is a generic feature of various quantum systems at low temperatures and it in particular important for the description dynamics energy nuclear reactions.The time-dependent density functional theory (TDDFT) is, to date, only microscopic method which takes into account consistent way far from equilibrium pairing field single-particle degrees freedom.The local version TDDFT, so called TDSLDA, particularly useful reactions well suited leadership class computers hybrid (CPU+GPU)...
