Confinement and chiral symmetry breaking in holography: a smooth switch-off
Martà Berenguer, Johanna Erdmenger, Nick Evans +2
We revisit the holographic description of the thermal first order phase transition of N=4 SYM compactified on a spatial circle. At the transition, the dominant bulk saddle exchange…

Gibbons-Hawking-York boundary terms and the generalized geometrical trinity of gravity
Johanna Erdmenger, Bastian HeÃ, Ioannis Matthaiakakis +1
General relativity (GR) as described in terms of curvature by the Einstein-Hilbert action is dynamically equivalent to theories of gravity formulated in terms of spacetime torsion…

Holography for Sp(2) Gauge Dynamics: from Composite Higgs to Technicolour
Johanna Erdmenger, Nick Evans, Yang Liu +1
We study Sp(2) gauge dynamics with two Dirac fermion flavours in the fundamental representation. These strongly coupled systems underlie some composite Higgs models with a glo…
