The mass spectra of quarkonium systems at T= 0 are analyzed by solving the non-relativistic radial wave equation using the internal energy potential. The QGP matter is studied through the dissociations of quarkonium states. A modified form of the internal energy potential functio...

Considering ‘black hole geometry’ as the ‘eternal cosmic geometry’ and by assuming ‘constant light speed rotation’ throughout the cosmic evolution, at any time the currently believed cosmic ‘critical density’ can be shown to be the cosmic black hole’s eternal ‘volume density’. Th...

Aims: For modeling of large polyatomic systems one may use the variation principle for energy density functional. The key point to make this is to find the functional of kinetic energy in the orbital-free approach. Study Design: We describe a way to find functionals of kinetic en...

Zitterbewegung is the quiver motion discovered by Schroedinger in his 1930 solution of the time-dependent Dirac equation for a free electron. The origin of Zitterbewegung is the interference between positive-energy and negative-energy states. Zitterbewegung is predicted to exist...
