Time-energy uncertainty relation from subcycle mode vacuum fluctuations of a quantum field
Achintya Sajeendran, Timothy C. Ralph
The time-energy uncertainty relation is often invoked as a heuristic explanation for virtual particles in interacting quantum field theories. However, this interpretation breaks do…

Looping back to the past through free fall in a controlled warp drive spacetime
Achintya Sajeendran, Timothy C. Ralph
We present a modification to a 'rotating' version of the dynamical Alcubierre spacetime, which was previously shown to permit closed timelike curves. We find that if the effective…
