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…
Angular and Kinetic Properties of Scission Neutrons within Time-dependent Density Functional Theory
Antonio Bjelčić, Ibrahim Abdurrahman, Kyle Godbey
Scission-neutron emission is investigated in , and $^{252}\mathrm{Cf…
Pair Transfer and Reaction Dynamics in Ca + Zr Collisions Below the Coulomb Barrier
Ibrahim Abdurrahman, Andrzej Makowski, Guillaume Scamps +2
Sub-barrier fusion reactions are ideal for probing the effects of pairing correlations on simultaneous neutron transfer. Previous calculations using the BCS approximation showed an…
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 $^{…
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…
Sensitivity to the initial conditions of the Time-Dependent Density Functional Theory
Aurel Bulgac, Ibrahim Abdurrahman, Gabriel Wlazłowski
Time-Dependent Density Functional Theory is mathematically formulated through non-linear coupled time-dependent 3-dimensional partial differential equations and it is natural to ex…
Fragment Intrinsic Spins and Fragments' Relative Orbital Angular Momentum in Nuclear Fission
Aurel Bulgac, Ibrahim Abdurrahman, Kyle Godbey +1
We present the first fully unrestricted microscopic calculations of the primary fission fragment intrinsic spins and of the fission fragments' relative orbital angular momentum for…
The LISE package: solvers for static and time-dependent superfluid local density approximation equations in three dimensions
Shi Jin, Kenneth J. Roche, Ionel Stetcu +2
Nuclear implementation of the density functional theory (DFT) is at present the only microscopic framework applicable to the whole nuclear landscape. The extension of DFT to superf…
Direct derivation of the comma 3-Vertex in the full string basis
A Abdurrahman, I Abdurrahman, M Gassem
The interacting comma 3-vertex for the bosonic open string in the full string basis is derived using the half string overlap relations directly. Thus avoiding the coherent states t…
