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…
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…
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…
Quantum turbulence, superfluidity, non-Markovian dynamics, and wave function thermalization
A. Bulgac, M. Kafker, I. Abdurrahman +1
While quantum turbulence has been addressed both experimentally (predominantly for superfluid He and He) and theoretically, the dynamics of various ensembles of quantized v…
Non-Markovian character and irreversibility of real-time quantum many-body dynamics
Aurel Bulgac, Matthew Kafker, Ibrahim Abdurrahman +1
The presence of pairing correlations within the time-dependent density functional theory (TDDFT) extension to superfluid systems, is tantamount to the presence of a quantum collisi…
Spatial orientation of the fission fragment intrinsic spins and their correlations
Guillaume Scamps, Ibrahim Abdurrahman, Matthew Kafker +2
New experimental and theoretical results obtained in 2021 made it acutely clear that more than 80 years after the discovery of nuclear fission we do not understand the generation a…
Neck Rupture and Scission Neutrons in Nuclear Fission
Ibrahim Abdurrahman, Matthew Kafker, Aurel Bulgac +1
Just before a nucleus fissions a neck is formed between the emerging fission fragments. It is widely accepted that this neck undergoes a rather violent rupture, despite no direct e…
Measures of complexity and entanglement in fermionic many-body systems
Aurel Bulgac, Matthew Kafker, Ibrahim Abdurrahman
There is no unique and widely accepted definition of the complexity measure (CM) of a many-fermion wave function in the presence of interactions. The simplest many-fermion wave fun…
