4. Compact objects and the swampland / Herdeiro, Carlos ; Radu, Eugen ; Uzawa, Kunihito
Recently, two simple criteria were proposed to assess if vacua emerging from an effective scalar field theory are part of the string “landscape” or “swampland”. [...]

5. The scalarised Schwarzschild-NUT spacetime / Brihaye, Yves ; Herdeiro, Carlos ; Radu, Eugen
It has recently been suggested that vacuum black holes of General Relativity (GR) can become spontaneously scalarised when appropriate non-minimal couplings to curvature invariants are considered. [...]
