  Title Black holes with primary hair in gauged N=8 supergravity Type Journal Article
  Year 2012 Publication Journal Of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume Issue 6 Pages 12 pp  
  Keywords Black Holes; Supergravity Models  
  Abstract In this paper, we analyze the static solutions for the U(1)(4) consistent truncation of the maximally supersymmetric gauged supergravity in four dimensions. Using a new parametrization of the known solutions it is shown that for fixed charges there exist three Possible black hole configurations according to the pattern of symmetry breaking of the (scalars sector of the) Lagrangian. Namely a black hole without scalar fields, a black hole with a primary hair and a black hole with a secondary hair respectively. This is the first, exact, example of a black hole with a primary scalar hair, where both the black hole and the scalar fields are regular on and outside the horizon. The configurations with secondary and primary hair can be interpreted as a spontaneous symmetry breaking of discrete permutation and reflection symmetries of the action. It is shown that there exist a triple point in the thermodynamic phase space where the three solution coexist. The corresponding phase transitions are discussed and the free energies are written explicitly as function of the thermodynamic coordinates in the uncharged case. In the charged case the free energies of the primary hair and the hairless black hole are also given as functions of the thermodynamic coordinates.

  Title C Ambitwistor pure spinor string in a type II supergravity background Type Journal Article
  Year 2015 Publication Journal Of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume Issue 6 Pages 15 pp  
  Keywords Superstrings and Heterotic Strings; Supergravity Models  
  Abstract We construct the ambitwistor pure spinor string in a general type II supergravity background in the semi-classical regime. Almost all supergravity constraints are obtained from nilpotency of the BRST charge and further consistency conditions from additional world-sheet the case of AdS(5) x S (5) background.

  Title On-shell type II supergravity from the ambitwistor pure spinor string Type Journal Article
  Year 2016 Publication Classical And Quantum Gravity Abbreviated Journal Class. Quantum Gravity  
  Volume 33 Issue 18 Pages 9 pp  
  Keywords supergravity models; superstrings; pure spinor string  
  Abstract We obtain all the type II supergravity constraints in the pure spinor ambit-wistor string by imposing consistency of local worldsheet gauge symmetries.
