Using particle accelerators to investigate the quark-gluon plasma of the infant universe
QGP atom neutron
<
2021/8/10
A new special edition of EPJ Special Topics brings together several papers that detail our understanding of Quark-Gluon Plasma (QGP) and the processes that transformed it into the baryonic matter we a...
'Ghost particles' could improve understanding the universe
Ghost particles understanding universe
<
2017/2/16
Trillions of neutrinos, or ghost particles, are passing through us every second. While scientists know this fact, they don’t know what role neutrinos play in the universe because they are devilishly h...

The purpose of the paper is five-fold: (a) Argue that the question in the title can be presented in a meaningful manner and that it requires an answer. (b) Discuss the conventional answers and explain...
One-dimensional universe of free particles: classical and quantum correspondence
Classical-quantum correspondence Wave packets Free particles
<
2010/3/10
We obtain multi-free particle parametric systems with complete classical-quantum correspondence. First, we quantize the classical parametric model which results in a hyperbolic partial differential eq...
Small Scale Magnetic Field Evolution In The First Objects Formed In The Universe
Small Scale Magnetic Field Evolution The First Objects In The Universe
<
2010/10/27
Large scale magnetic fields in galaxies are thought to be generated, by a mean field dynamo. In order to have generated the fields observed, the dynamo would have had to have operated for a sufficient...
Inflation in a Flat Universe
Flat Universe Inflation
<
2010/4/13
We started the evolution of a flat universe from a nonsingular state called prematter which is governed by an inflationary equation of state P=(g -1)r , where g represents the initial vacuum dominance...
Some String Cosmological Models in Cylindrically Symmetric Inhomogeneous Universe
String Cosmological Models
<
2010/4/15
The aim of this paper is to investigate the behavior of a string in the cylindrically symmetric inhomogeneous cosmological model. It has been assumed that expansion q in the model is proportional to s...
