On Holography in General Background and the Boundary Effective Action from AdS to dS
Sylvain Fichet
We study quantum fields on an arbitrary, rigid background with boundary. We derive the action for a scalar in the holographic basis that separates the boundary and bulk degrees of…

Dressing in AdS and a Conformal Bethe-Salpeter Equation
Sylvain Fichet
We initiate the study of Dyson equations of perturbative QFT in AdS and their consequences for large-N CFT. We show that the dressed one-particle AdS propagator features wavefuncti…

Continuum-Mediated Self-Interacting Dark Matter
Ian Chaffey, Sylvain Fichet, Philip Tanedo
Dark matter may self-interact through a continuum of low-mass states. This happens if dark matter couples to a strongly-coupled nearly-conformal hidden sector. This type of theory…
