  • Stability of generic cylindrical thin shell wormholes 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Amirabi, Zahra (Physical Review D, American Physical Society (APS), 2014)
    We revisit the stability analysis of cylindrical thin shell wormholes which have been studied in literature so far. Our approach is more systematic and in parallel to the method which is used in spherically symmetric thin ...
  • Thin-shell wormholes from the regular Hayward black hole 
    Halilsoy, Mustafa; Övgün, Ali; Mazharimousavi, S. Habib (The European Physical Journal C, Springer, 2014-03-13)
    We revisit the regular black hole found by Hayward in 4 -dimensional static, spherically symmetric spacetime. To find a possible source for such a spacetime we resort to the nonlinear electrodynamics in general relativity. ...
  • A topological metric in 2+1-dimensions 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa (European Physical Journal C, Springer, 2015)
    Real-valued triplet of scalar fields as source gives rise to a metric which tilts the scalar, not the light cone, in 2+1-dimensions. The topological metric is static, regular and it is characterized by an integer κ=±1,±2,.... ...
  • Uninformed Hawking radiation 
    Sakallı, İzzet; Övgün, Ali (EPL, IOP Publishing (Institute of Physics), 2015-04-24)
    We show in detail that the Parikh-Wilczek tunneling method (PWTM), which was designed for resolving the information loss problem in Hawking radiation (HR) fails whenever the radiation occurs from an isothermal process. ...
