Classical antiparticles
We review how antiparticles may be introduced in classical relativistic mechanics, and emphasize that many of their paradoxical properties can be more transparently understood in the classical than in the quantum domain.
متن کاملVacancy island creation and coalescence using automated scanning tunneling microscopy.
We demonstrate that scanning tunneling microscope tip-surface crash events can be utilized as an efficient means for the creation of predefined island configurations for diffusion studies. Using this method, islands of varying size can be created and placed in close proximity, increasing the probability of initiating and observing coalescence events. Data obtained from crash initiated events on...
متن کاملSchwinger pair creation of Kaluza – Klein particles : Pair creation without tunneling ∗ Tamar Friedmann
We study Schwinger pair creation of charged Kaluza-Klein particles from a static KK electric field. We find that the gravitational backreaction of the electric field on the geometry – which is incorporated via the electric KK Melvin solution – prevents the electrostatic potential from overcoming the rest mass of the KK particles, thus impeding the tunneling mechanism which is often thought of a...
متن کاملPoint form relativistic quantum mechanics, antiparticles and
Point form relativistic quantum mechanics, antiparticles and exchange currents. Abstract It is shown that the dynamical observables calculated with the point form rela-tivistic quantum mechanics incorporate effects of particle-antiparticle creation from the vacuum by interactions. The electromagnetic observables obtained with the point form impulse approximation include contributions from the "...
متن کاملJa n 20 05 Induced tunneling in QFT : soliton creation in collisions of highly energetic particles
Induced tunneling in QFT: soliton creation in collisions of highly energetic particles. Abstract We consider tunneling transitions between states separated by an energy barrier in a simple field theoretical model. We analyse the case of soliton creation induced by collisions of a few highly energetic particles. We present semiclassical, but otherwise first principle, study of this process at al...
