Nuclear energy density optimization [PDF]

Physical Review C, 2010
We carry out state-of-the-art optimization of a nuclear energy density of Skyrme type in the framework of the Hartree-Fock-Bogoliubov (HFB) theory. The particle-hole and particle-particle channels are optimized simultaneously, and the experimental data set includes both spherical and deformed nuclei.

A tabletop, ultrashort pulse photoneutron source driven by electrons from laser wakefield acceleration

Matter and Radiation at Extremes, 2017
Relativistic electron beams driven by laser wakefield acceleration were utilized to produce ultrashort neutron sources. The experiment was carried out on the 38 fs, ∼0.5 J, 800 nm Ti:Sapphire laser in the 10 TW UT3 laser lab at University of Texas at ...

Vacuum radiation induced by time dependent electric field

Physics Letters B, 2017
Many predictions of new phenomena given by strong field quantum electrodynamics (SFQED) will be tested on next generation multi-petawatt laser facilities in the near future.

Numerical studies on electron magnetohydrodynamics tearing mode instability

AIP Advances, 2021
The 2D electron-magnetohydrodynamics (EMHD) dominant tearing mode in an electron-skin-depth-scale current sheet (ECS) is further studied. The resistive diffusion is proved to be insignificant at the scale.

CONSTRAINTS ON THE DENSITY DEPENDENCE OF THE SYMMETRY ENERGY [PDF]

International Journal of Modern Physics E, 2009
Collisions involving 112 Sn and 124 Sn nuclei have been calculated with the ImQMD transport model in order to place constraints on the density dependences of the nuclear symmetry energy. Consistent constraints on the symmetry energy at sub-saturation density have been obtained by comparing these transport calculations to measurements of isospin ...

Electromagnetic energy density in hyperbolic metamaterials

Scientific Reports, 2022
AbstractWe present the theory of electromagnetic energy propagation through a dispersive and absorbing hyperbolic metamaterial (HMM). In this way, the permittivity tensor components of HMM (especially, nanowire HMM) may appear to be hopeless, but as a non-trivial step, we find that they can be cast into more transparent forms.

The BCS Energy Gap at High Density

Journal of Statistical Physics, 2022
AbstractWe study the BCS energy gap $$\Xi $$ Ξ in the high–density limit and derive an asymptotic formula, which strongly depends on the strength of the interaction potential V on the Fermi surface. In combination with the recent result by one of us (Math. Phys. Anal. Geom.

Sensitivity and effectivity of Kim’s novel electro-thermodynamic cycle over Olsen cycle on waste heat recovering with high fluctuating temperature source using lead-free pyroelectric Ba(Zr0.1Ti0.9)O3

AIP Advances, 2021
A novel electro-thermodynamic cycle with a higher waste heat recovery efficiency than the conventional Olsen cycle was introduced by Kim et al. in 2015. Thus, in the present study, the importance of the temperature factors was investigated, revealing the

The effect of the plasma response on peeling–ballooning modes during edge localized modes mitigated by resonant magnetic perturbations

Nuclear Fusion, 2023
The effects of resonant magnetic perturbation (RMP) fields on peeling–ballooning (P–B) modes are studied with the experimental equilibria of EAST based on the four-field model in BOUT++ code.

On the Representation of Effective Energy Densities [PDF]

ESAIM: Control, Optimisation and Calculus of Variations, 2000
The paper under review deals with a question raised in [\textit{R. Choksi} and \textit{I. Fonseca}, Arch. Ration. Mech. Anal. 138, No. 1, 37-103 (1997; Zbl 0891.73078)] on the representation of relaxed energies given as a sum of bulk and surface integrals. More precisely, given the functional \[ E(u)= \int_\Omega W(\nabla u) dx+ \int_{S_u} \phi([u],\nu)
