Speaker

Dr Hoang Nguyen (Babes-Bolyai University)

Description

In this talk, I shall present a novel class of non-Schwarzschild asymptotically flat metrics in exact closed analytical form for pure $R^2$ gravity (Phys. Rev. D 106 (2022) 10, 104004). They were recently derived from a program originated by Buchdahl in 1962. I shall also discuss the existence of Morris-Thorne-Buchdahl wormholes using the metrics.
