Critical Fields = Critical Acceleration = Particle Production
Johann Rafelski (Physics Department,
The University of Arizona)
After a
review of the quantum instability of the vacuum in presence of super
critical fields I will develop the cross-connection with the ultra-high
acceleration phenomena, and describe the related riddles the
unit-strength critical acceleration generates in the context of
classical electromagnetism: radiation friction, and in the related EM
component in the mass of charged elementary particles. Critical
acceleration phenomena maybe at the origin of the entropy generation
required for QGP formation. The lecture closes with the introduction of
new experimental strong field physics opportunities arising in the
context of ultra-intense light pulse collisions with relativistic
particles.
Personal
memories about the Frankfurt School of Theoretical Physics and
contributions of Joachim
Reinhardt in the area of strong
fields enrich this presentation.
Parts of this lecture are drawn from a
recently completed "Relativity Matters" book which can be downloaded
