On parity-odd sector in metric-affine theories
Jose Beltrán Jiménez, Alejandro Jiménez-Cano, Yuri N. Obukhov
We undertake the construction of quadratic parity-violating terms involving the curvature in the four-dimensional metric-affine gravity. We demonstrate that there are only 12 linea…
Instabilities in field theories: Lecture notes with a view into modified gravity
Adrià Delhom, Alejandro Jiménez-Cano, Francisco José Maldonado Torralba
Modified theories of gravity usually present new degrees of freedom, as well as higher order derivatives, wrong signs in certain terms and complicated couplings already present in…
Vector stability in quadratic metric-affine theories
Alejandro Jiménez-Cano, Francisco José Maldonado Torralba
In this work we study the stability of the four vector irreducible pieces of the torsion and the nonmetricity tensors in the general quadratic metric-affine Lagrangian in 4 dimensi…
Metric-Affine Gauge theories of gravity: Foundations and new insights
Alejandro Jiménez-Cano
This thesis covers several developments performed in metric-affine gravity. This alternative framework extends General Relativity by considering a more general connection than the…
