2+1 dimensional solution of Einstein Cartan equations
M. Hortacsu, H. T. Ozcelik, N. Ozdemir
In this work a static solution of Einstein-Cartan (EC) equations in 2+1 dimensional space-time is given by considering classical spin-1/2 field as external source for torsion of th…
Spherical symmetric charged solution with cosmological constant
N. Ozdemir
A spherically symmetric charged ideal fluid solution of Einstein field equation is given in the presence of the cosmological constant and two well known example of this type of sol…
Spinning cosmic strings: a general class of solutions
N. Ozdemir
In this work, we give a general class of solutions of the spinning cosmic string in Einstein's theory of gravity. After treating same problem in Einstein Cartan (EC) theory of grav…
Exact metric around a wiggly cosmic string
N. Ozdemir
The exact metric around a wiggly cosmic string is found by modifying the energy momentum-tensor of a straight infinitely thin cosmic string to include an electric current along the…
Quantum Fluctuations for Gravitational Impulsive Waves
Y. Enginer, M. Hortacsu, N. Ozdemir
Quantum fluctuations for a massless scalar field in the background metric of spherical impulsive gravitational waves through Minkowski and de Sitter spaces are investigated. It is…
An Extension of Multiple Cosmic String Solution
M. Hortacsu, N. Ozdemir
We extend the work done for cosmic strings on the perturbative calculation of vacuum polarization of a massless field in the space-time of multiple cosmic strings and show that for…
