Euclidean quantum wormholes
Autor: Farook Rahaman, Bikramarka S. Choudhury, Anikul Islam
Publikováno v: European Physical Journal C: Particles and Fields, Vol 84, Iss 8, Pp 1-12 (2024)
Abstract We study wormhole as the solution of the Wheeler–DeWitt (WdW) equation satisfying Hawking–Page wormhole boundary conditions in Friedmann–Robertson–Walker (FRW) cosmology. The quantum wormholes are formulated with arbitrary factor ord

Gravitational deflection of massive body around naked singularity
Autor: Md Khalid Hossain, Keita Takizawa, Anikul Islam, Shyam Das, Farook Rahaman
Publikováno v: Nuclear Physics B, Vol 1005, Iss , Pp 116598- (2024)
Spacetime singularity is not observed directly as it is covered by event horizon. Naked singularities may be formed due to gravitational collapse without an event horizon. Therefore, cosmic censorship conjecture entails advanced ascertainment. Recent
