Space-time and Quantum Mechanics are the pillars of our modern understanding of fundamental physics. But there are storm clouds on the horizon, indicating that these principles are approximate, and must be replaced with something deeper. The union of quantum mechanics and gravity strongly suggests that “space-time is doomed”, and there are related indications of fundamental limitations to quantum mechanics in both the early and late universe. In this talk I will review these paradoxes and describe indications for a new picture where space-time and quantum mechanics will be seen to emerge hand-in-hand from more primitive principles, making contact with new areas of mathematics. I will give a concrete example of how these ideas work in the context of particle collision experiments, of the sort performed at the Large Hadron Collider.

Nima Arkani-Hamed is one of the leading theoretical physicist of his generation with broad interests in high-energy and mathematical physics as well as cosmology. His research has shown how the extreme weakness of gravity, relative to other forces of nature, might be explained by the existence of extra dimensions of space, and how the structure of comparatively low-energy physics is constrained within the context of string theory. He has taken a lead in proposing new physical theories that can be tested at the Large Hadron Collider at CERN in Switzerland. His recent work focuses on a reformulation of the foundations of quantum field theory. He was educated at Toronto and Berkeley and was a professor of physics at Berkeley and Harvard before joining the Institute for Advanced Study in Princeton in 2008. He was an inaugural recipient of the Fundamental Physics Prize in 2012, and was one of six physicists featured in the award-winning documentary “Particle Fever” in 2014.

IGST 2016

Integrability has played a major role in the historical development of theoretical physics. Newton was able to exactly derive the Kepler laws from his novel theory of mechanics and gravity. Quantum mechanics established itself as a mathematically and physically correct theory through the exact solution of the idealized hydrogen atom. In both cases, the hidden conservation of the Laplace-Runge-Lenz vector underlies these successes. Thus, the integrability of the central force problem is related to breakthroughs in both classical and quantum mechanics. It is widely felt that a similarly idealized model is needed to uncover the mysteries of gauge and string theory in general, and the intricate mechanism of the holographic principle in particular. This is the core topic of the “Integrability in Gauge and String Theory” (IGST) conference series, whose 2016 edition will take place in Berlin.

Focus is on integrability in holographic systems such as the AdS/CFT correspondence in various dimensions. Recent years have seen spectacular progress on both the gauge and string theory sides of certain holographically dual models, allowing for exact computations of operator spectra, scattering problems, correlation functions, and Wilson loops. The latest developments will be reviewed at this conference. Emphasis is on the solution of specific problems, but the mathematical structures underlying integrability are explored as well. Closely related topical fields such as lattice approaches, QCD string modeling, entanglement entropy studies and general CFT approaches will also be represented.

We plan on 25 talks of 45 minutes each, with some additional time for questions. In order to reflect the latest developments, the list of talks will only be finalised in the weeks preceding the meeting.
