Black holes and scalar fields
Abstract
With the recent discovery of the Higgs boson and the detection of gravitational waves, the study of scalar fields and black holes became important directions of research in modern physics. In this talk, we shall start by reviewing the basic aspects of these two seemingly unconnected subjects. The tension between the existence of black holes and the presence of non-trivial scalar field configurations, as encoded in the black hole 'no hair' conjecture, will also be discussed. Finally, we shall review a number of recent results which circumvent the 'no hair' conjecture, allowing for black holes surrounded by 'scalar clouds', with potential relevance in astrophysics.
