In summary, a search for Quark-gluon_plasma on arxiv.org in 2008 yielded 112 hits. A new search for Quark-gluon liquid gave 1391 hits. The status and properties of Quark-gluon plasma are discussed in various papers, indicating that it is a liquid that can turn into a solid under certain conditions. The phase diagram and transition between hadronic matter and quark matter is also explored in some papers. The web has made it easier to access information and learn about these topics.

The Fluid Nature of Quark-Gluon Plasma
Authors: W.A. Zajc
(Submitted on 25 Feb 2008)
The current status of the RHIC experimental studies is presented, with a special emphasis on the fluid properties of the created matter, which may in fact be the most perfect fluid ever studied in the laboratory.

This is cool!
I have now found that Quark-Gluon Plasma is a liquid.
By releasing the pressure and lowering the temp it turns into a solid. (H III)
I wonder what impact it will have on the timeline of the B.B.?

I could not find a discussion of Quark-Gluon liquid on this forum.
I’ve always assumed that whatever I thought of has been thought of before me and that someone with more education and dedication has worked out the details.
I have not been disappointed.
My search has been facilitated by the web. (You could say that I’m barely a teenager.) hehehe
I’m just an amateur discovering how “the wheel” was invented/made.
If you do not like my “popularization style” of communicating then
Do read the following paper. and give me your para-phrasing.

The Phase Diagram of Strongly-Interacting Matter
Authors: P. Braun-Munzinger, J. Wambach
(Submitted on 28 Jan 2008)
In this article we discuss physical aspects of the phase diagram, its relation to the evolution of the early universe as well as the inner core of neutron stars. We also summarize recent progress in the experimental study of hadronic or quark-gluon matter under extreme conditions with ultrarelativistic nucleus-nucleus collisions.

It’s great to be able to "surf" the web and find out that someone has done some number crunching about something that I was wondering.

Phase transition from hadronic matter to quark matter
Authors: P. Wang, A. W. Thomas, A. G. Williams
last revised 3 Apr 2007
The phase transition from nuclear matter to quark matter is always first order, whereas the transition between color superconducting quark matter and normal quark matter is second order.
The phase transition between hadronic matter and quark matter can only occur at high density or temperature.
 

1. What is a quark-gluon liquid?

A quark-gluon liquid is a state of matter that existed in the early universe, shortly after the Big Bang. It is made up of the fundamental particles known as quarks and gluons, which are the building blocks of protons and neutrons. In this state, these particles are not confined within individual particles, but rather flow freely, creating a liquid-like state.

2. How is this state of matter relevant to understanding the early universe?

The quark-gluon liquid is believed to have existed in the first few microseconds after the Big Bang, when the universe was extremely hot and dense. By studying this state of matter, scientists can gain insight into the conditions of the early universe and how it evolved into the universe we see today.

3. How do scientists study the quark-gluon liquid?

Scientists use particle accelerators, such as the Large Hadron Collider, to recreate the extreme conditions of the early universe and produce a quark-gluon liquid. They then observe the behavior of the particles in this state and analyze the data to understand its properties.

4. What are the potential applications of studying the quark-gluon liquid?

Studying the quark-gluon liquid can help us better understand the fundamental forces and particles of the universe. It can also aid in the development of new technologies, such as more efficient energy production and advanced materials.

5. What are some current findings and research surrounding the quark-gluon liquid?

Recent research has shown that the quark-gluon liquid behaves like a perfect fluid, with very low viscosity and a strong resistance to flow. Scientists are also studying the phase transition from this state to the more familiar state of matter, known as a quark-gluon plasma. There is still much to be discovered and understood about this fascinating state of matter.
