Correlation Functions in Low-Dimensional AdS/CFT

The AdS/CFT correspondence is a remarkable conjecture relating quantum gravity (more precisely, string thoery) and interacting conformal field theories. Remarkably, for a few instance of AdS/CFT it appears to be possible to perform exact computations on either side of the duality. This allows to work out two-, three-, four- and in some cases higher-point correlation functions, as well as to account for non-planar effects (stringy loops). The techniques used for this purpose stem from the the theory of integrable models and of conformal quantum field theories, but have to be adapted to the case of supersymmetric strings.

The aim of this workshop is to bring together experts in the field of exact computations in AdS/CFT with expertise in string theory, supergravity, integrability, and conformal field theory. This workshop is organised in conjuction with the conference Great Lessons from Exact techniques and Beyond which takes place at the university of Padova in the period 21—25 September, 2020.

Villa Garbald is a facility of ETH Zurich, but is not located in Zurich. Rather it is right on the border with Italy, between Chiavenna and Bregaglia. It takes little less than 5 hours to get there from Zurich, and little less than 4 from Milan (by public transport; coming by car takes 3h and 2h30, respectively).

• From Zurich by public transport it is necessary to go to Chur, change train to St Moritz and take a public bus (bus n. 4 in direction "Chiavenna") from St Moriz to the conference venue (stop "Castasegna - Vecchia Dogana").
• From Milano by public transport, it is necessary to reach Chiavenna, which can be done by train with a change in Colico. From there, one should continue by public bus (bus n. 4 in direction "St Moritz") from Chiavenna to the conference venue (stop "Castasegna - Vecchia Dogana").
• Participants coming from north of Switzerland can also go directly to Chur by train or by long-distance bus and continue to St Moritz - Castasegna.

For information on local travel in Switzerland see www.sbb.ch. Since reaching Castasegna from the main Swiss airports and cities require a relatively long trip, we advise participants to consider purchasing a one-day travelcard, which is relaticely cheap (if bought in advance) and valid on all trains and buses (and most boats) in Switzerland.

For long-distance buses to Zurich and Chur see e.g. www.flixbus.ch. For local trains in Lombardia (the Milano region) see www.trenord.it.

Participants attending the conference Great Lessons from Exact techniques and Beyond at the University of Padova will be able to take advantage of an organised private minibus to Castasegna. The bus will depart from Padova on the morning of September 26. Further details will be given by email.
