4. Implications of RQM Flashcards
1
Q
What is the Klein paradox, and how is it explained?
A
If the potential is big enough, the incident current is less than the reflected current
- Explained by if V > 2m, get particles and anti particles created which will move away from the barrier
2
Q
How is helicity effected by rotations about an axis?
A
It is unchanged
3
Q
How are boosts and the rapidity related?
A
Boosts act as a rotation but with a hyperbolic function
- Theta is the rapidity angle
- tan(theta) = Beta = v/c
4
Q
How are Maxwell’s equations invariant?
A
They are gauge invariant
