    Recently we have shown that for 2+1−dimensional thin-shell wormholes a non-circular throat may lead to a physical wormhole in the sense that the energy conditions are satisfied. By the same token, herein we consider angular ...

    The model proposed originally by Mannheim and Kazanas for fitting the shapes of galactic rotation curves has recently been considered by Grumiller to describe gravity of a central object at large distances. Herein we employ ...

    In this paper, we focus on the quantization of 4−dimensional rotating linear dilaton black hole (RLDBH) spacetime describing an action, which emerges in the Einstein-Maxwell-Dilaton-Axion (EMDA) theory. RLDBH spacetime has ...

    Gürtuğ, Özay; Mazharimousavi, S. Habib; Halilsoy, Mustafa (Advances in High Energy Physics, Hindawi Publishing Corporation, 2015)
    The formation of naked singularities in 2+1-dimensional power-law spacetimes in linear Einstein-Maxwell and Einstein-scalar theories sourced by azimuthally symmetric electric field and a self-interacting real scalar field, ...

    Gürtuğ, Özay; Halilsoy, Mustafa; Mazharimousavi, S. Habib (Journal of High Energy Physics, Springer, 2014)
    The formation of a naked singularity in f(R) global monopole spacetime is considered in view of quantum mechanics. Quantum test fields obeying the Klein−Gordon, Dirac and Maxwell equations are used to probe the classical ...
