Axion Electrodynamics in Curved Spacetime

This research line focuses on axion and axion-like-particle electrodynamics in curved spacetime, with applications to compact objects, neutron-star magnetospheres, and gravitational-wave environments.

The goal is to formulate and explore the coupled dynamics of axion fields and electromagnetic fields in a relativistic setting, using a 3+1 decomposition adapted to numerical and semi-analytical studies. This framework is especially useful for investigating how spacetime curvature, strong magnetic fields, and plasma effects may influence axion-photon conversion and electromagnetic signatures.

Main topics

• Axion-Maxwell theory in curved spacetime.
• 3+1 decomposition of axion electrodynamics.
• Axion-photon conversion in magnetized compact-object environments.
• Gravitational-wave modulation of electromagnetic and axionic fields.
• Numerical pipelines for exploratory relativistic simulations.
