Large Amplitude Collective Motion and Dissipation in the Ground State and the First Isomeric Wells in the Neutron-Induced Fission of U
Ibrahim Abdurrahman, Matthew Kafker, Aurel Bulgac +1
In fission induced by low energy neutrons, the mother nucleus spends a significant fraction of the time in the ground state and isomer wells, eventually passing beyond the outer ba…
Influence of the Exit Channel in U(n,f) and Pu(n,f) Reactions in Time-Dependent Density Functional Theory
Ibrahim Abdurrahman, Matthew Kafker, Aurel Bulgac +1
This study investigates the consequences of the intrinsic deformation of the fissioning nuclear system near the outer saddle point on the shape evolution of the nucleus from saddle…
Impact of the Center of Mass Fluctuations on the Ground State Properties of Nuclei
Matthew Kafker, Aurel Bulgac
Ground state properties across the entire nuclear chart are described predominantly and rather accurately within the density functional theory (DFT). DFT however breaks many symmet…
Multi-Nucleon Transfer Reactions and the Creation and the Evolution of the Compound Nucleus
Matthew Kafker, Aurel Bulgac
We present the first implementation of a novel extension of the Generator Coordinate Method (GCM), dubbed the enhanced GCM (eGCM), which is applied to the grazing Multi-Nucleon Tra…
Non-Equilibrium Dynamics of Hard Spheres in the Fluid, Crystalline, and Glassy Regimes
Matthew Kafker, Xerxes D. Arsiwalla
We investigate the response of a system of hard spheres to two classes of perturbations over a range of densities spanning the fluid, crystalline, and glassy regimes within a molec…
Non-Equilibrium Aspects of Fission Dynamics within the Time Dependent Density Functional Theory
A. Bulgac, M. Kafker, I. Abdurrahman +1
We will cover briefly the time-dependent density functional theory approach, extended to include pairing correlations, to induced fission of U(n,f), Pu, and $^{…
