Previous years:

Organized by Shamit Kachru (Stanford University), Hirosi Ooguri (Caltech) and Subir Sachdev (Harvard University), this is the third symposium on this topic.

Since the first symposium in 2013, quantum entanglement has become even more important in a broad area of theoretical physics ranging from condensed matter physics and quantum information toquantum gravity and string theory. It does appear that the symposia anticipated this impact, and played a role in developing some of the connections between different branches of theoretical physics. Quantum entanglement and its relation toquantum error correction is playing a key role in our understanding of bulk reconstruction in holography. The connections between black holes, fast scrambling, and quantum chaos are other subjects we plan to discuss at the symposium. In particular, the Sachdev-Ye-Kitaev model has been found to be maximally chaotic and seems to provide a solvable model of holography in which the boundary quantum theory is tractable in a regime which captures the subtle correlations in Hawking radiation. In condensed matter physics, entanglement acts as one of the few `tags’ for topologically ordered states, novel phases of matter not characterized by conventional order parameters. This has been particularly powerful in studies of gapped systems.

More recently, a rich web of dualities was discovered in 2+1 dimensions relating some of the simplest critical theories of interest in condensed matter physics. These dualities may be useful in improving understanding of central ideas such as ‘flux attachment’ and the physics of the composite Fermi liquid. All of these recent developments make it an excellent time to bring together theorists in these areas to share their insights and tools.

    TEA & DISCUSSION Pavillion located at the Schloss Elmau Retreat
    EXCURSION Meet in Schloss Elmau Lobby
    SATURDAY DEPARTURE Meet in Schloss Elmau Lobby

    *Participants may explore the hotel property and its surrounding areas as well as engage in informal discussion with other participants.

    Start Time

    The meeting will begin on Monday morning at 10:00 am in the Pavillon meeting room located at the Schloss Elmau Retreat. Breakfast will start at 8:30 am in La Salle restaurant.

    Meeting Location

    All symposium activities will take place in the Pavillon meeting room located at the Schloss Elmau Retreat.


    Participants will have access to a projector and screen for computer based talks as well as blackboards for those who prefer to give board-based talks. High-speed Internet access is available as well.

    Wednesday Excursion

    On Wednesday symposia activities will be shortened so that anyone interested may attend a hiking excursion. Participants will embark on a fully guided hiking tour from Schloss-Elmau through the Partnach Gorge. The hike difficulty is moderate and will take approximately 3 hours.

    Dress Code

    Business casual clothing should be worn during the symposia. The weather can change very quickly so we also advise bringing warm-weather clothing appropriate for spring in the mountains.

    If you plan on taking part in the hike to Partnach Gorge we advise you to wear hiking boots, or even better, light mountain boots, warm clothing (e.g. a sweater), sun protection (e.g. light cap) and take waterproofs (e.g. raincoat or umbrella) with you. Bringing along a small backpack or satchel in which to carry your water, camera and other items may also be useful to you.
