Frenet-Serret equations with variable proper acceleration in Minkowski spacetime
Ivan Perez-Roman, Michael R. R. Good, Yen Chin Ong +1
We study Frenet-Serret equations for timelike worldlines in Minkowski spacetime with proper-time-dependent curvature and torsion. This corresponds to relativistic motion with non-u…
Measurement-Induced Perturbations of Hausdorff Dimension in Quantum Paths
You-Wei Ding, Yen Chin Ong, Hao Xu
In a seminal paper, Abbott et al. analyzed the relationship between a particle's trajectory and the resolution of position measurements performed by an observer at fixed time inter…
Problems of Massive Gravities
S. Deser, K. Izumi, Y. C. Ong +1
The method of characteristics is a key tool for studying consistency of equations of motion; it allows issues such as predictability, maximal propagation speed, superluminality, un…
Superluminal Propagation and Acausality of Nonlinear Massive Gravity
S. Deser, K. Izumi, Y. C. Ong +1
Massive gravity is an old idea: trading geometry for mass. Much effort has been expended on establishing a healthy model, culminating in the current ghost-free version. We summariz…
Massive Gravity Acausality Redux
S. Deser, K. Izumi, Y. C. Ong +1
Massive gravity (mGR) is a 5(=2s+1) degree of freedom, finite range extension of GR. However, amongst other problems, it is plagued by superluminal propagation, first uncovered via…
