Particles: Effects  

In General > s.a. field theory; particle models [relativistic quantum mechanics vs quantum field theory]; particle types; quantum field theory.
* Idea: The notion of particle requires that of a timelike Killing vector field; In Minkowski space there is a natural choice, but in general relativity it is ambiguous; Also, it is defined only when there are no interactions; Only for small λ, high frequency, one has an approximate notion; The problem is equivalent to that of defining an appropriate Feynman propagator.
* In 2D: They can belong to a 1D representation of the braid group (anyons), or other (superstrings, ...).

Particle Creation / Production by Electromagnetic Fields
* Schwinger effect: The quantum pair production of charged particles in a strong electric field; > s.a. inflation [quantum perturbations].
* Dynamically assisted Sauter-Schwinger effect: The enhanced Schwinger effect in the superposition of a strong and slow electric field with a weaker and faster pulse.

Particle Creation / Production by Gravitational Fields > s.a. black-hole radiation; horizons; quantum field theory effects in curved spacetime.
* Remark: The effect is determined by the square of the Weyl tensor; This motivates a definition of entropy (Penrose), but how to go from one to the other is not known.
