Magnetic Effect on the Potential Barrier for Nucleosynthesis
Kiwan Park
We demonstrated that a weak magnetic field can increase the permittivity, leading to a reduction in the potential barrier within the Debye sphere consisting of electrons and a nucl…
Negative Turbulent Magnetic Diffusivity effect in a Magnetically Forced System
Kiwan Park, Myung-Ki Cheoun
We have studied the large scale dynamo process forced with helical magnetic energy. The magnetically driven dynamo is not so well studied as kinetically forced dynamo. It has been…
On the Inverse Transfer of (Non-)Helical Magnetic Energy in a Decaying Magnetohydrodynamic Turbulence
Kiwan Park
In our conventional understanding, large-scale magnetic fields are thought to originate from an inverse cascade in the presence of magnetic helicity, differential rotation, or a ma…
Dynamo model for the inverse transfer of magnetic energy in a nonhelical decaying magnetohydrodynamic turbulence
Kiwan Park
The inverse cascade of magnetic energy occurs when helicity or rotational instability exists in the magnetohydrodynamic (MHD) system. This well known phenomenon has been considered…
Evolution of Kinetic and Magnetic Energy in Intra Cluster Media
Kiwan Park, Dongho Park
Intra Cluster Media (ICMs) located at galaxy clusters is in the state of hot, tenuous, magnetized, and highly ionized X-ray emitting plasmas. This overall collisionless, viscous, a…
Influence of small scale and on the growth of large scale magnetic field
Kiwan Park
We investigated the influence of small scale magnetic energy () and magnetic helicity () on the growth rate () of large scale magnetic field (). $H_M…
A study of large scale dynamo growth rates from numerical simulations and implications for mean field theories
Kiwan Park, Eric G. Blackman, Kandaswamy Subramanian
Understanding large scale magnetic field growth in turbulent plasmas in the magnetohydrodynamic limit is a goal of magnetic dynamo theory. In particular, assessing how well large s…
Simulations of a Magnetic Fluctuation Driven Large Scale Dynamo and Comparison with a Two-scale Model
Kiwan Park, E. G. Blackman
Models of large scale (magnetohydrodynamic) dynamos (LSD) which couple large scale field growth to total magnetic helicity evolution best predict the saturation of LSDs seen in sim…
