Plasma Frequency.
Plasmas have a number of natural modes of oscillation.
The most fundamental perhaps is the electron plasma oscillations.
The ions can also oscillate at their own natural frequency as, for example. In standing acoustic waves.
This frequency is called the Ion Plasma Frequency.
Methods of ionization:
Electron Impact Ionization.
Photo Ionization.
Field Ionization.
Surface Ionization.
(Field ionization from sharp points at which very intense electric fields are created)
Applications of Plasmas created by Nano-Second Laser Pulses:
Concerning applications of Laser produced plasmas, we can just distinguish between two forms.
Those which exploit: 1. the Hydrodynamics induced by strong shock waves associated to the ablative pressure-
And: 2. those exploiting the radiation emitted by the plasma.
Laser generated intense pressure, multi-magabar ablative pressures are employed for studying the properties of dense compressed matter, and for driving inertial confinement fusion implosions.
Radiation Hydrodynamics experiments and scaled-down simulations of astrophysical phenomena.
CPA Lasers.
Chirped Pulse Lasers-
Addresses GeV energy scales and Femtosecond scales.
Chirped Pulse Lasers are also referred to as “Relativistic Lasers”.
Relativistic Laser Plasmas.
The advent of CPA Lasers has opened the rapidly growing field of Relativistic Plasma Physics.
Relativistic electrons generated emit an intense flux of X-Rays and Gamma Rays, (and so protection from this environment generated becomes paramount). Also important to note is that Satellites used to monitor the Treaty on the ban of above ground nuclear tests will “see” this Non-Thermal Gamma Ray Burst.
The form of Plasma we will be discussing here will always be Light Ion plasmas, so the proper choice in gas or combination of gases becomes important. What we will be looking for cannot be done with Heavy Ion Gases, only the light forms.
Reissner-Nordstrom Black Hole: A spherically symmetric with Time-Like singularities (Infinite universes each with their own singularity), repeating forever in both past and future time directions like a strip of paper dolls cut out of folded paper. To construct a R-N black hole, you need a lot of matter, highly charged with a single electric polarity (either very positive or very negative). Intense electric fields created by these isolated charges would ionize any matter present into like charge.
Solutions due to repulsive electrostatic force opposing gravitational contraction “Holds Open The Door” to other universes.
Like the electrostatic force in a R-N black hole, centrifugal force associated with a rotating body acts fo oppose gravitational collapse.
Closed Time-Like Loops (curves) / Closed Temporal loops/(CTL’s).
Frank Tipler has shown that one cannot form a CTL without also producing a singularity somewhere.
In the real world there might well be unusual initial conditions that lead in a natural way to the formation of CTL’s in space-time.
Space-Time;
According to Minkowski, Special Relativity functions as a kind of Law of Perspective in four dimensions. Relative motion between two observers is equivalent to a rotation in four dimensional.
Roy Kerr solved Einstein’s equations for a rapidly rotating mass.
The Kerr Black Hole singularity is not a point, but takes the form of a ring encircling the axis of rotation. Because of the singularities ring shape, it is possible to travel to the exact center of the Kerr hole without encountering a region of infinite curvature.
This gives rise to another peculiar effect, the negative space-time region: when passing through the hole’s center, either distance becomes negative or gravity becomes negative (repulsive) negative space-time.
Once entering the ring, you go back in time. The only way to get out, is to exit into a different
universe from the one you left. This exit universe may, or may not be the same as the entrance universe.
Ezra Newman extended the Kerr solution where the rotating mass is also charged. This brings forth one addition: A Kerr-Newman Black Hole offers the opportunity for time travel without the necessity of diving through the ring singularity into negative space-time: Time travel is possible without
leaving ordinary space-time. Highly charged, rapidly rotating massive gravity is, of course, ordinary. Characterised by the values of just two parameters: The holes mass, and it’s angular momentum.
