Gravitational interactions of finite thickness global topological defects with black holes

L Perivolaropoulos - Physical Review D, 2018 - APS
It is well known that global topological defects induce a repulsive gravitational potential for
test particles.“What is the gravitational potential induced by black holes with a cosmological …

Higher-dimensional black holes with Dirac–Born–Infeld (DBI) global defects

HS Ramadhan, I Prasetyo, AM Kusuma - General Relativity and …, 2018 - Springer
It is well-known that the exact solution of non-linear σ σ model coupled to gravity can be
perceived as an exterior gravitational field of a global monopole. Here we study Einstein's …
