A Bit Rate Bound on Superluminal Communication
Xi Tong, Yi Wang, Yuhang Zhu
We study semi-classical communication in positivity-violating k-essence scalar field theories, with superluminal modes propagating on a rolling background. The self-interactions du…

Gravitational Collider Physics via Pulsar-Black Hole Binaries
Qianhang Ding, Xi Tong, Yi Wang
We propose to use pulsar-black hole binaries as a probe of gravitational collider physics. Induced by the gravitation of the pulsar, the atomic transitions of the boson cloud aroun…

Gauge Invariance, Polar Coordinates and Inflation
Ali Akil, Xi Tong
We point out the necessity of resolving the apparent gauge dependence in the quantum corrections of cosmological observables for Higgs-like inflation models. We highlight the fact…
