Gravity with a Dynamical Spinning Aether
Christopher Kohler
Einstein-aether theory is extended by allowing for spinning degrees of freedom of the aether. In addition to the acceleration, shear, expansion, and vorticity of the aether velocit…
Large resistivity change and phase transition in LiMnAs
A. Beleanu, J. Kiss, G. Kreiner +16
Antiferromagnetic semiconductors are new alternative materials for spintronic applications and spin valves. In this work, we report a detailed investigation of two antiferromagneti…
Five-Dimensional Unification of the Cosmological Constant and the Photon Mass
C. Kohler
Using a non-Riemannian geometry that is adapted to the 4+1 decomposition of space-time in Kaluza-Klein theory, the translational part of the connection form is related to the elect…
Torsion Degrees of Freedom in the Regge Calculus as Dislocations on the Simplicial Lattice
Juergen Schmidt, Christopher Kohler
Using the notion of a general conical defect, the Regge Calculus is generalized by allowing for dislocations on the simplicial lattice in addition to the usual disclinations. Since…
Semi-Teleparallel Theories of Gravitation
C. Kohler
A class of theories of gravitation that naturally incorporates preferred frames of reference is presented. The underlying space-time geometry consists of a partial parallelization…
Einstein-Cartan-Maxwell Theory with Scalar Field through a Five-Dimensional Unification
C. Kohler
A modification of Kaluza-Klein theory is proposed in which, as a result of a symmetry breaking, five-dimensional space-time is partially parallelized implying the appearance of tor…
Geometric Classification of Topological Quantum Phases
C. Kohler
On the basis of the principle that topological quantum phases arise from the scattering around space-time defects in higher dimensional unification, a geometric model is presented…
