Massless spin-2 fields via lower spins
Özgür Açık, Ümit Ertem
Solutions of massless spin-2 field equations are written in terms of massless spin- Rarita-Schwinger fields and twistor spinors. It is shown that the proposed massless…

Choices of spinor inner products on M-theory backgrounds
Ümit Ertem, Özgün Sütemen, Özgür Açık +1
M-theory backgrounds in the form of unwarped compactifications with or without fluxes are considered. We construct the bilinear forms of supergravity Killing spinors for different…

Effect of Modified Dispersion Relations on Immirzi Parameter
Ö. Açık, Ü. Ertem
Black hole entropy calculations which are based on counting of microstates and based on modified dispersion relations in the framework of loop quantum gravity are considered. We su…
