Bag Model

We study a simplified model for the chiral bag plus Skyrmion hybrid model (CSH) in which the vacuum polarization due to the chiral Casimir effect is approximated by the anti-Skyrmion configuration. We closely investigate to what extent this model is available and find it provides a very similar result to those of the CSH model for the bag radius R≳0.4 fm.

Virtual Pairs

Vacuum polarization rearranges virtual  pairs. This causes the virtual  pairs to rigidify in vacuum, reducing the quantum fluctuation energy. The quantum fluctuation energy is a fundamental force of vacuum, as evidenced by the Casimir effect. The change in quantum fluctuation energy was simulated in the superposition of the electric fields. The results show that the increase and decrease of the quantum fluctuation energy between the two point charges is related to the repulsive force and attraction in Coulomb's law.

Laser Acceleration

Laser acceleration of electrons in laser fields of intensities above 1028 W/cm2 were found to be in the same range as acceleration at the surface of black holes, where the laser intensities are in the range of pair production in vacuum due to vacuum polarization. The results in connection with the black holes arrived at similarities to the Hawking and Unruh radiation. We present here results based on the thermodynamics of the vacuum fluctuations that there is a difference between Hawking and Unruh effects in connection with the Casimir effect in view of the vacuum properties for laser produced pairs in a vacuum.
