TL;DR
This paper investigates rotating black holes with monopole hair in Einstein-Yang-Mills-Higgs theory, revealing their bifurcation with Kerr-Newman black holes and properties like electric dipole moments and gyroelectric ratio.
Contribution
It introduces rotating black hole solutions with monopole hair, showing their emergence from static solutions and bifurcation with Kerr-Newman black holes.
Findings
Black holes with monopole hair emerge from static solutions under rotation.
These black holes bifurcate with Kerr-Newman black holes at critical parameters.
They have an electric dipole moment but no induced electric charge due to rotation.
Abstract
We study rotating black holes in Einstein-Yang-Mills-Higgs theory. These black holes emerge from static black holes with monopole hair when a finite horizon angular velocity is imposed. At critical values of the horizon angular velocity and the horizon radius, they bifurcate with embedded Kerr-Newman black holes. The non-Abelian black holes possess an electric dipole moment, but no electric charge is induced by the rotation. We deduce that gravitating regular monopoles possess a gyroelectric ratio g_el=2.
