CFT complexity and penalty factors

Journal of High Energy Physics
Quantum complexity of conformal field theory (CFT) states has recently gained significant attention, both as a diagnostic tool in condensed matter systems and in connection with holographic observables probing black hole interiors.

Chiral interactions of fermions and massive gauge fields in Kaluza-Klein models

Journal of High Energy Physics
In Kaluza-Klein theory, gauge fields on M 4 arise as components of a higher-dimensional metric defined on M 4 × K. The traditional expectation is that all the gauge fields of the Standard Model are linked to exact Killing vector fields on the internal ...

Canonical submersions in nearly Kähler geometry

Complex Manifolds
We explore submersions introduced by reducible holonomy representations of connections with parallel skew torsion. A submersion theorem extending previous, less general, results is given. As our main application, we show that parallel 3-(α,δ)\left(\alpha

Internal symmetries in Kaluza-Klein models

Journal of High Energy Physics
The usual approach to Kaluza-Klein considers a spacetime of the form M 4 × K and identifies the isometry group of g K 0 $$ {g}_K^0 $$ , the internal vacuum metric, with the gauge group in four dimensions.
