Torsionful Killing-Yano Forms under T-Duality: Transformation Conditions and Emergent Isometries
Özgür Kelekçi, Ümit Ertem, Özgür Açık
We investigate the transformation of Killing-Yano (KY) -forms under Abelian T-duality in the presence of a non-trivial three-form torsion. Using a torsionful, metric-compatible…
Motion of membranes in space-times with torsion
Özgür Açık, Aytolun Çatalkaya, Ümit Ertem +1
The motion of membranes interacting with external fields in space-times with curvature and torsion is considered. The intrinsic and extrinsic properties of the immersion are fused…
Generalized symmetry superalgebras
Özgür Açık, Ümit Ertem
We generalize the symmetry superalgebras of isometries and geometric Killing spinors on a manifold to include all the hidden symmetries of the manifold generated by Killing spinors…
Spin-1/2 and spin-3/2 field solutions in plane wave spacetimes
Özgür Açık
We have found two non-trivial massless Dirac and two massive Rarita-Schwinger solutions in plane wave spacetimes. The first order symmetry operator transforming one of the massless…
Spin raising and lowering operators for Rarita-Schwinger fields
Özgür Açık, Ümit Ertem
Spin raising and lowering operators for massless field equations constructed from twistor spinors are considered. Solutions of the spin- massless Rarita-Schwinger equa…
Field equations from Killing spinors
Özgür Açık
From the Killing spinor equation and the equations satisfied by their bilinears we deduce some well known bosonic and fermionic field equations of mathematical physics. Aside from…
