ENERGY–MOMENTUM DENSITY OF GRAVITATIONAL WAVES [PDF]

International Journal of Modern Physics A, 2008
In this paper, we elaborate the problem of energy–momentum in general relativity by energy–momentum prescriptions theory. Our aim is to calculate energy and momentum densities for the general form of gravitational waves. In this connection, we have extended the previous works by using the prescriptions of Bergmann and Tolman.

Correlated energy from radial density–energy relations

Royal Society Open Science, 2023
Here, we demonstrate that the radial distribution function can be mapped into a radial density–energy space and the relationship between the radial density and radial energy is linear for the ground and excited states of helium-like systems; the gradient of the resulting straight line delivers the energy of the state considered. To utilize this finding,

Effective theory for low-energy nuclear energy density functionals [PDF]

, 2012
We introduce a new class of effective interactions to be used within the energy-density-functional approaches. They are based on regularized zero-range interactions and constitute a consistent application of the effective-theory methodology to low-energy

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.

RELATIVISTIC NUCLEAR ENERGY DENSITY FUNCTIONALS [PDF]

International Journal of Modern Physics E, 2010
A class of relativistic nuclear energy density functionals is explored, in which only nucleon degrees of freedom are explicitly used in the construction of effective interaction terms. Short-distance correlations, as well as intermediate and long-range dynamics, are encoded in the nucleon-density dependence of the strength functionals of an effective ...

Relativistic nuclear energy density functional constrained by low-energy QCD [PDF]

, 2006
A relativistic nuclear energy density functional is developed, guided by two important features that establish connections with chiral dynamics and the symmetry breaking pattern of low-energy QCD: a) strong scalar and vector fields related to in-medium ...

The nuclear energy density functional formalism [PDF]

, 2013
The present document focuses on the theoretical foundations of the nuclear energy density functional (EDF) method. As such, it does not aim at reviewing the status of the field, at covering all possible ramifications of the approach or at presenting ...

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.

Local and Global Casimir Energies for a Semitransparent Cylindrical Shell [PDF]

The local Casimir energy density and the global Casimir energy for a massless scalar field associated with a $\lambda\delta$-function potential in a 3+1 dimensional circular cylindrical geometry are considered. The global energy is examined for both weak
