Weyl double copy in Lifshitz spacetimes
Gokhan Alkac, Mehmet Kemal Gumus, Mehmet Ali Olpak
Lifshitz black hole solutions pose particular challenges for reconciling the two main formulations of the classical double copy: the Kerr-Schild double copy and the Weyl double cop…
Charmonium content of in light-cone sum rules at twist 3
Tarik Akan, Mehmet Ali Olpak, Altug Ozpineci
In this study, we utilize light-cone QCD sum rules at twist-3 accuracy to compute the coupling parameters of the state with and mesons. The analysis reveals…
Classical double copy in the black hole mini-superspace
Gokhan Alkac, Mehmet Kemal Gumus, Mehmet Ali Olpak
We give a novel formulation of classical double copy in the mini-superspace of static, spherically symmetric black holes where the map between the solutions of general relativity a…
Regularized Weyl double copy
Gokhan Alkac, Mehmet Kemal Gumus, Oguzhan Kasikci +2
We propose a regularization procedure in the sourced Weyl double copy, a spinorial version of the classical double copy, such that it matches much more general results in the Kerr-…
Generalized Black Holes in 3D Kerr-Schild Double Copy
Gokhan Alkac, Mehmet Kemal Gumus, Mehmet Ali Olpak
The double copy of the Coulomb solution in three dimensions is a non-vacuum solution that can be obtained through different matter couplings. It is the static black hole solution o…
Kerr-Schild Double Copy of the Coulomb Solution in Three Dimensions
Gokhan Alkac, Mehmet Kemal Gumus, Mehmet Ali Olpak
While the Kerr-Schild double copy of the Coulomb solution in dimensions higher than three is the Schwarzschild black hole, it is known that it should be a non-vacuum solution in th…
On the calculation of covariant expressions for Dirac bilinears
Mehmet Ali Olpak, Altug Ozpineci
In this article, various approaches to calculate covariant expressions for the bilinears of Dirac spinors are presented. For this purpose, algebraic equations defining Dirac spinor…
Light Cone Distribution Amplitudes of Excited P-Wave Heavy Quarkonia at the Leading Twist
M. A. Olpak, A. Ozpineci, V. Tanriverdi
Leading twist light cone distribution amplitudes (LCDAs) are key ingredients in calculating various hadronic amplitudes using light cone QCD sum rules. This work concentrates on ca…
Quantum Mechanics on Curved Hypersurfaces
Mehmet Ali Olpak
In this work, Schrödinger and Dirac equations will be examined in geometries that confine the particles to hypersurfaces. For this purpose, two methods will be considered. The firs…
Dirac Equation on a Curved 2+1 Dimensional Hypersurface
Mehmet Ali Olpak
Interest on 2 + 1 dimensional electron systems has increased considerably after the realization of novel properties of graphene sheets, in which the behaviour of electrons is effec…
