Description

Thematic six-weeks program at Institut Henri Poincaré, Paris.

January 09th - February 17th, 2023.

The scope of the program is to bring together researchers who are working on quantum gravity from various perspectives and approaches, with an emphasis on the random geometry point of view and on more recent holographic developments. The main goal is to intensify the fruitful interactions between the researchers in these and related communities in order to make significant progress on the outstanding problems in quantum gravity.

## Program :

The thematic six-weeks program will include two workshops (weeks 2 and 5), introductory lectures (weeks 1 and 4), two general public lectures, and more (informal gatherings and seminars).

Lectures and workshop seminars will be live streamed on the IHP website, and available later on carmin.tv.

11, Rue Pierre et Marie Curie 75005 Paris

Loop quantum gravity is a background-independent approach to the
quantization of general relativity. The fundamental states of the
theory are described by spin networks, states associated with graphs
whose quantum numbers give the spectra of discrete and non-commuting
geometric operators. On a fixed graph, the quantum numbers can be
interpreted as a collection of fuzzy polyhedra describing a twisted
geometry. The maths describing the twisted geometry uses an amusing
interplay of symplectic geometry, group theory and Regge geometry
which I will describe in some details. There is also a connection to
twistors that I will briefly discuss.

11, Rue Pierre et Marie Curie 75005 Paris

Lattice quantum field theory has been very successful as a tool to study non-perturbative aspects of quantum field theory. These lectures describe how the QUANTUM theory of General Relativity can also be formulated as a lattice theory. It is (very) successful in the case of two-dimensional spacetimes. There are several ways to generalize the two-dimensional lattice theory to higher dimensions, but amazingly they lead to the same modified Friedmann equation that seems to resolve all tension present between early time and late time cosmological data. The modified Friedmann equation has no cosmological constant. Instead the present expansion of the universe is caused by the creation of baby universes and links the dynamics of the very early universe to its final destiny.

Quantum groups in a (coco) nutshell 1h Amphitheater Darboux

### Amphitheater Darboux

#### IHP

11, Rue Pierre et Marie Curie 75005 Paris

(Lie) Groups are typically seen as encoding a symmetry structure. For some phase spaces, the symmetry structure might need to be equipped with a non-trivial Poisson structure, which must then be compatible with the group product (to have a well defined symmetry action). This defines the notion of Poisson Lie group. When quantizing the system, the Poisson Lie group becomes a quantum group. I will provide a compact introduction to these concepts having in mind as leading example, the 3d (quantum) gravity framework, where such Poisson Lie/quantum symmetries are key to understand the quantum theory.

11, Rue Pierre et Marie Curie 75005 Paris

After a brief review of the original argument due to Maldacena for a holographic duality between IIB string theory on
AdS$_5\times$S$^5$ and maximally supersymmetric Yang-Mills theory, we turn to the duality between the free O(N)
vector model in 2+1 dimensions and higher spin gravity on AdS$_4$. For this theory we study the spectrum of single
trace primaries of the CFT, which is dual to the spectrum of fields in higher spin gravity. By formulating the CFT in terms
of bilocal variables, using the formalism of collective field theory, we demonstrate how the gravitational theory can be
constructed. This example demonstrates a number of recently discovered phenomena in quantum gravity including the
quantum error correction interpretation of holography, entanglement wedge reconstruction and the holography of information.

### Amphitheatre Hermite

Random tensors exhibit a 1/N expansion dominated by melonic graphs. The large N limit of these models is thus richer than the large N limit of vector models, but more amenable to computations than the one of matrix models. This series of lectures is divided into two parts. In the first part I will review the melonic large N limit in combinatorial tensor and vector/tensor models. In the second part I will discuss the O(N)^3 field theory in the large N limit.
