Non-local observables in AdS/CFT: finite temperature results — •Nina Miekley1,2 and Johanna Erdmenger1,2 — 1Julius-Maximilians-Universitaet Wuerzburg, Germany — 2Max-Planck-Institut für Physik, Munich, Germany
The AdS/CFT correspondence relates strongly coupled field theories to theories containing gravity. One interesting aspect are non-local observables, for instance the two-point function, the Wilson loop and the entanglement entropy. Their dual descriptions are associated to minimal surfaces. We derive a closed, analytic form of the aforementioned observables for d-dimensional finite temperature CFTs dual to Schwarzschild-AdS. Of particular interest is the high-temperature limit, where our results allow insights into new physical behaviour, e.g. a violation of the area theorem for entanglement entropy and a renormalisation of the quark mass.
