... 2. The 4-momentum (defined by the action of the Poincare group on the Hilbert space) is positive, i.e., its spectrum is contained within the closed future light cone (“spectrum condition”). 3. There exists a unique, Poincare invariant state (“the vacuum”). 4. The quantum fields are operator-valued ...

Lorentz Invaiance Violation and Granularity of space time
... Let us take up the notion that space-time contains some granular/discrete aspect with characteristic scale given by MPlanck The lesson from the previous studies is that such structure, if exists, can not lead to breakdown of Lorentz Invariance. It is of course hard to envision something like that wh ...

... 1. Find the 2 × 2 matrix representing a counter-clockwise rotation (by angle φ about the n̂ direction), of the spin wavefunction of a spin- 12 particle. Express the answer as a linear combination of the identity and Pauli matrices. 2. Show that the exchange operator acting on the Hilbert space of tw ...
