Exploring Zeptosecond Quantum Equilibration Dynamics: From Deep-Inelastic to Fusion-Fission Outcomes in Ni+Ni Reactions
E. Williams, K. Sekizawa, D. J. Hinde +10
Energy dissipative processes play a key role in how quantum many-body systems dynamically evolve towards equilibrium. In closed quantum systems, such processes are attributed to th…
Pairing dynamics and time dependent density functional theory
P. Magierski, J. Grineviciute, K. Sekizawa
We discuss issues related to pairing dynamics in nuclear large amplitude collective motion. The examples of effects which are not properly described within BCS theory are presented…
Suppressed solitonic cascade in spin-imbalanced superfluid Fermi gas
Gabriel Wlazłowski, Kazuyuki Sekizawa, Maciej Marchwiany +1
Cold atoms experiments offer invaluable information on superfluid dynamics, including decay cascades of topological defects. While the cascade properties are well established for B…
Enhanced nucleon transfer in tip collisions of U+Sn
Kazuyuki Sekizawa
Multinucleon transfer processes in low-energy heavy ion reactions have attracted increasing interest in recent years aiming at production of new neutron-rich isotopes. Clearly, it…
Deep-inelastic multinucleon transfer processes in the O+Al reaction
B. J. Roy, Y. Sawant, P. Patwari +16
The reaction mechanism of deep-inelastic multinucleon transfer processes in the O+Al reaction at an incident O energy ( MeV) substantially abo…
Solitonic excitations in collisions of superfluid nuclei: a qualitatively new phenomenon distinct from the Josephson effect
Kazuyuki Sekizawa, Gabriel Wlazłowski, Piotr Magierski
Recently, we have reported a novel role of pairing in low-energy heavy ion reactions at energies above the Coulomb barrier, which may have a detectable impact on reaction outcomes,…
Microscopic description of production cross sections including deexcitation effects
Kazuyuki Sekizawa
Background: At the forefront of the nuclear science, production of new neutron-rich isotopes is continuously pursued at accelerator laboratories all over the world. To explore the…
Solitonic Excitations in Collisions Of Superfluid Nuclei
Kazuyuki Sekizawa, Piotr Magierski, Gabriel Wlazłowski
We investigate the role of the pairing field dynamics in low-energy heavy ion reactions within the nuclear time-dependent density functional theory extended to superfluid systems.…
