Holographic Dual to Conical Defects: II. Colliding Ultrarelativistic Particles

Understand

We study instant conformal symmetry breaking as a holographic effect of ultrarelativistic particles moving in the AdS3 spacetime.

• We give the qualitative picture of this effect probing it by two-point correlation functions and the entanglement entropy of the corresponding boundary theory.
• We show that within geodesic approximation the ultra-relativistic massless defect due to gravitational lensing of the geodesics, produces a zone structure for correlators with broken conformal invariance.
• Meanwhile, the holographic entanglement entropy also exhibits a transition to the non-conformal behaviour.
