  • Constant curvature f(R) gravity minimally coupled with Yang-Mills field 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Tahamtan, Tayebeh (European Physical Journal C, Springer, 2011)
    We consider the particular class of f(R) gravities minimally coupled with Yang - Mills (YM) field in which the Ricci scalar =R_{0}= constant in all dimensions d\geq4. Even in this restricted class the spacetime has unlimited ...
  • Existence of Reissner-Nordstrom type black holes in f(R) gravity 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Kerachian, Morteza (International Journal of Modern Physics D, World Scientific Publishing, 2013)
    We investigate the existence of Reissner-Nordstr\"om (RN) type black holes in f(R) gravity. Our emphasis is to derive, in the presence of electrostatic source, the necessary conditions which provide such static, spherically ...
  • A scan of f(R) models admitting Rindler type acceleration 
    Mazharimousavi, S. Habib; Kerachian, Morteza; Halilsoy, Mustafa (European Physical Journal C: Particles and Fields, Springer, 2014)
    As a manifestation of large distance effect Grumiller modified Schwarzschild metric with an extraneous term reminiscent of Rindler acceleration. Such a term has the potential to explain the observed flat rotation curves ...
