Beyond the unitarity bound in AdS/CFTQMAP Seminar

AdS/CFT is a broad term that refers to the correspondence between
gravitational theories and quantum field theories (QFT) in one lower dimension. The seemingly
different nature of both theories raises the question of how the various features of
each description are related to one another. In the best understood examples, it turns
out that the QFT's are conformal field theories (CFT), which, if required to be
unitary, cannot contain operators whose conformal dimension is below a certain bound. In this talk,
we will examine the implications of this bound on the gravitational side via a simple
toy model example involving a scalar field. If time permits, we shall discuss the extension of our results
to Maxwell fields and gravitons.
