How to Unbalance Nothingness:
Physicists Calculate the Time Development of the Vacuum Decay


"The ground state of our world can't be described by the absence of
all matter,"
Professor Dr. Holger Gies from the Institute of Theoretical Physics of
the
Friedrich-Schiller-University Jena and the Helmholtz-Institute Jena
explains.
"This so-called quantum vacuum rather turns out to be a complex
state of constantly fluctuating quantum fields with physical
properties."

The world-wide community of physicists is hoping to be able to witness
a particularly spectacular characteristic in a few years' time:
the spontaneous decay of the vacuum into pairs of particles of matter
and antimatter in super strong electric fields.
Thanks to new research results of the Austro-German team of
physicists,
this goal came a few steps closer.

Describe Quantum Fields out of Equilibrium

Although first theoretical consideration concerning the spontaneous
decay of the vacuum dates back to the year 1931, its comprehensive
understanding is still in its infancy.
"A great challenge in modern theoretical physics is the description
of quantum fields out of equilibrium," Professor Gies explains.
"We are facing this problem in phase transitions in the early
Universe
as well as in many experiments in solid state physics."

Therefore experimental proof of the vacuum decay -- as it might be
delivered by high intensity lasers in the near future -- will provide
knowledge exceeding this particular field.
The scientists from Graz and Jena now succeeded calculating the time
evolution of the vacuum decay in detail.

"Even we were surprised by the results," Professor Gies confesses.
According to the results particles of matter and antimatter behave
in a novel self-focusing way and therefore the possibility of
discovering
them is higher than expected.
"The quantum vacuum has already had some surprises in store,"
says the Heisenberg-Professor for Theoretical Physics.
"To unbalance this nothingness could develop into a new prolific
field of research."
The results of this co-operation have just been published in the
journal
Physical Review Letters.

My questions and opinion.

What are physical parameters of Vacuum?
What are physical parameters of ‘so-called quantum vacuum’?

What is difference between vacuum and ‘so-called quantum vacuum’?

The reason that ‘quantum fields out of equilibrium,’ is polarization
of vacuum.

What is mechanism of ‘ the self energy ‘ polarization?
Nobody tries to explain the mechanism of this process.
