Holographic Entanglement and BMS blocks in three dimensional flat space

I will discuss the holographic construction of entanglement entropy and  blocks in three-dimensional flat space-times. I will present a prescription based on world-line methods  in the probe limit, inspired by recent analog calculations in AdS/CFT. Building on this construction, a full extrapolate dictionary will be proposed, and used  to compute holographic correlators and blocks away from the probe limit. Blocks  involving heavy operators will be shown to involve probe particles propagating in flat space cosmologies.
