DOI: 10.1007/s10714-018-2351-y
Abstract: Heun-type exact solutions emerge for both the radial and the angular equations for the case of a scalar particle coupled to the zero mass limit of both the Kerr and Kerr-(anti)de-Sitter spacetime. Since any type… read more here.

DOI: 10.1007/s11128-019-2277-7
Abstract: We study time evolution of quantum Fisher information (QFI) and entanglement for two three-level atomic systems influenced by Stark effect and Kerr-like medium. It is seen that Stark and Kerr media play dominant role during… read more here.
