Towards a group structure for superluminal velocity boosts

MJ Lake - arXiv preprint arXiv:2409.01773, 2024 - arxiv.org
Canonical subluminal Lorentz boosts have a clear geometric interpretation. They can be
neatly expressed as hyperbolic rotations, that leave both the family of $2 $-sheet …

Covariant quantum field theory of tachyons is unphysical

K Jodłowski - Physical Review D, 2024 - APS
Tachyons have fascinated generations of physicists due to their peculiar behavior, but they
did not solve any real physical problem. This may have changed with the recent works of …
