Local scale symmetry and black holes
Malik Almatwi
We derive solutions for a black hole coupled to a real scalar field under considerations of local scale symmetry. Starting with the simple case , we find the solutions and d…
Interaction of a black hole with scalar field in cosmology background
Malik Almatwi
Recent data from elliptical galaxies indicate that the growth in the masses of black holes exceeds what is expected from the accretion of surrounding matter, and this growth appear…
Non-minimally coupled scalar field and scaling symmetry in a cosmological background
Malik Al Matwi
We study scaling symmetry in a class of non-minimally coupled scalar field in a background of Friedmann-Robertson-Walker (FRW) spacetime. We use a non-minimally coupling $R L^{(φ)}…
Spin current in BF theory
Malik Matwi
In this paper, we introduce a current which we call spin current corresponding to the variation of the matter action in BF theory with respect to the spin connection which take…
