A numerical study of the Lieb-Thirring kinetic energy lower bound
(Taylor and Francis, 2016)
In this work, the Lieb-Thirring kinetic energy bound is numerically examined for a variety of systems: the hydrogen-like atoms, neutral atoms, isoelectronic series of atomic ions, the Hooke's atom and some small molecules. ...
Empirical analysis of the Lieb-Oxford bound in ions and molecules
(JOHN WILEY & SONS INC, 2008)
Universal properties of the Coulomb interaction energy apply to all many-electron systems. Bounds on the exchange-correlation energy, in particular, are important for the construction of improved density functionals. Here ...
Three- and Four-Nucleon Bound States in Three Dimensions, Without PW Decomposition
(American Institute of Physics (AIP), 2012-01-01)
A brief review of a three-dimensional (3D) numerical method to solve few-nucleon bound and scattering states, without the standard partial-wave (PW) decomposition, is presented. The approach is applied to three-and ...

J/Ψ mass shift and J/Ψ-nuclear bound state
(2011-08-16)
We calculate mass shift of the J/Ψ meson in nuclear matter arising from the modification of DD, DD* and D*D* meson loop contributions to the J/Ψ self-energy. The estimate includes the in-medium D and D* meson masses ...
Optimal energy generation with biomass of sugarcane harvest
(2011-05-31)
The aim of this work is the application of the Interior Point and Branch and Bound methods in multiobjective optimization models related to sugarcane harvest residual biomass. These methods showed their viability to help ...
A lower bound for the energy of symmetric matrices and graphs
(2017)
The energy of a symmetric matrix is the sum of the absolute values of its eigenvalues. We introduce a lower bound for the energy of a symmetric matrix partitioned into blocks. This bound is related to the spectrum of its ...
On the lower bound on the exchange-correlation energy in two dimensions
(Elsevier Science, 2010-02)
We study the properties of the lower bound on the exchange-correlation energy in two dimensions. First we review the derivation of the bound and show how it can be written in a simple density-functional form. This form ...
On the lower bound on the exchange-correlation energy in two dimensions
(ELSEVIER SCIENCE BV, 2010)
We study the properties of the lower bound on the exchange-correlation energy in two dimensions. First we review the derivation of the bound and show how it can be written in a simple density-functional form. This form ...
