what is the 5th state of matter
can aybody explain it
can aybody explain it
rayveldkamp said:I did a 2nd year undergrad uni course in statistical mechanics this semester, and we touched on Bose-Einstein condensation, just by deriving certain temperatures etc.
We were told that the first experimental evidence of B-E condensation was in 1995 where Rubidium atoms were cooled to something like 4x10^-3 K, by using "laser traps"
How does this work?
wolverine said:You must know the 3 states of matter: liquid,solid,gaz, but at hight temerature, you can also find a state called plasma(electrons are free)
The fifth state of matter you're talking about might be the QGP (Quarks and GLuon PLasma).
Scientists believe that QGP is a state where quarks are free (T = 170 Mev and epsilon = 3 GeV per fm^3), as during the first second of our universe.
Many experiments are runing now to prove its existence in Berkeley and Geneva...
I hope it's answers your question ...

The fifth state of matter is known as the Bose-Einstein condensate (BEC) and it is a unique form of matter that exists at extremely low temperatures, close to absolute zero (-273.15°C or -459.67°F).
The fifth state of matter is created by cooling a gas, usually composed of atoms, to a temperature very close to absolute zero. This causes the atoms to slow down and come together, forming a single entity known as a Bose-Einstein condensate.
The properties of the fifth state of matter include superfluidity, where the BEC can flow without friction and form vortices; and coherence, where all the particles in the BEC behave in a coordinated manner. It also exhibits wave-like behavior and can be manipulated with lasers.
The BEC has potential applications in precision measurements, quantum computing, and quantum simulation. It has also been used to create new states of matter and study fundamental physics principles.
The fifth state of matter was predicted by physicist Satyendra Nath Bose and Albert Einstein in the 1920s. It was first observed in 1995 by Eric Cornell and Carl Wieman, who were awarded the Nobel Prize in Physics for their work on the BEC in 2001.
