We find the expectation value of the energy-momentum tensor in the CFT corresponding to a moving black hole in AdS. Boosting the black hole to the speed of light, keeping the total energy fixed, yields a gravitational shock wave in AdS. The analogous procedure on the field theory side leads to ``light cone'' states, i.e., states with energy-momentum tensor localized on the light cone. The correspondence between the gravitational shock wave and these light cone states provides a useful tool for testing causality. We show, in several examples, how the CFT reproduces the causal relations in AdS.

    hep-th 2026-07 conditional novelty 7.0 of 10

    Timelike entanglement entropy in 2d CFT is defined by time-ordered twist correlators, whose holographic saddles are complex geodesics with smallest real length, and whose imaginary part counts causal-diamond crossings...

    In the AdS3/BTZ holographic setup, the expectation value of a scalar primary in a bulk wave-packet state exhibits temperature-dependent exponential decay along the light cone, absent at zero temperature, while the ene...

  4. The entropy of radiation for local quenches in higher dimensions

    hep-th 2025-01 conditional novelty 5.0 of 10

    For local quenches in d>2 CFTs, the excess entanglement entropy of radiation grows as ξ^{d/2} at early and late times, obeys an all-time relative-entropy bound, and the holographic model produces a Page-like curve.
