We reviewed the large N limit in physical theories with matrix valued degrees of freedom. In the 't Hooft limit, we learn the 1/N expansion is controlled by the topology of the Feynman diagrams.
Correlation functions of single trace operators factorise, at leading order, suggesting these behave like classical point particles where 1/N can be interpreted as an effective Planck's constant.

Lecture series: String Theory: The Very Basics
About this lecture series
String theory is currently the most successful theory of quantum gravity and is one of the most researched areas of theoretical physics today. The aim of this course is to give a flavour of the basics of the subject to students with a working knowledge of general relativity and some exposure to quantum field theory. Although the above is assumed, I would try and make the course as self-contained as is possible. We would mainly concentrate our attention on the bosonic string theory mentioning along ...

Lecture series: Holography lectures by Joan Simon
We introduced the main logic and ideas behind the decoupling limits (low energy limits) used to argue the existence of AdS/CFT.
First, we explored these under arguably very general and reasonable conditions. Once more, as the physical system comes close to being extremal, i.e. scale invariant, some AdS geometry emerges in the gravitational description of the system.
Second, we discussed the conditions under which gravity is weakly coupled and which CFTs have a chance to have gravity duals and, if so, when they may be described by ...

Lecture series: Holography lectures by Joan Simon
Given the equality of partition functions between boundary and bulk theories, and the dictionary between boundary sources and non-normalisable modes in the bulk, we derived a formal expression to compute euclidean correlation functions.
We applied this formula to reproduce the 2-pt function in the boundary CFT using bulk methods. This required to evaluate the bulk action on-shell and to add a counter-term to get a finite answer.
We briefly commented on how to extend this calculation to compute higher point functions. One can achieve this either using the same ...

We described the Ryu-Takayanagi holographic proposal to compute this quantity at strong coupling in AdS/CFT.

Lecture series: Holography lectures by Joan Simon
We continued our discussion on the gauge nature of GR :
stressing the difference between local and large diffeomorphisms
the latter giving rise to asymptotic symmetries
Having stressed the problem of finding a UV completion of GR remains opened, we listed two properties we believe such theory must satisfy :
there are no local gauge invariant observables
the graviton can not be a composite particle (Weinberg- Witten theorem)
This allowed us to stress the lack of locally conserved energy momentum stress tensor in general covariant theories.
To include further items in ...

Lecture series: Holography lectures by Joan Simon
In this lecture, we argue that the large N limit of matrix valued degrees of freedom can be interpreted as a strong theory. This is achieved by observing the inclusion of interactions in a quantum mechanical consistent way in string theory is also controlled by the topology of the closed 2d surfaces.
Mathematically, the perturbative string amplitudes with external string states have the same expansion as the connected correlators of single trace operators in the matrix model with the identification g_s=1/N, external strings as single trace operators ...

We reviewed some CFT basics, including the operator-state correspondence, and concluded reminding the matching of parameters between the CFT and the string theory on AdS.
As the first consequence of the duality, we stressed the UV/IR connection between bulk and boundary, both at zero and finite temperatures, giving some heuristic evidence for the extra dimension in AdS to provide some geometerisation of the energy scale in the boundary theory.
In the last part of the lecture, we ask for the dual of CFT operators. We guessed these should ...

Furthermore, requiring the periodicity at space like infinity to match the formal temperature of the black hole fixed the proportional between area and entropy to be 1/4, reproducing Hawking's discovery.

Lecture series: Holography lectures by Joan Simon
We asked whether black holes should be considered as quantum objects :
thermodynamic considerations of matter in the presence of black holes suggest the second law gets violated unless we include the Bekenstein-Hawking area term. Even if we do, the entropy of matter systems should be bounded by its energy and size (Bekentein's bound). This triggered the generalised second law.
revisiting the process of black hole formation, we reach the conclusion the entropy of matter systems in some bounded region of space should be smaller of equal than the ...

Lecture series: Holography lectures by Joan Simon
We want to understand whether the temperature parameter appearing in our GR analysis has any physical meaning. We discussed two ways to describe thermal system in matter systems :
We noticed that in a quantum system involving two harmonic oscillators, there could be more than one "vacuum", using squeezed states.

Lecture series: Holography lectures by Joan Simon
Armed with path integrals and the discussion on the Rindler geometry, we computed the wave function for the Minkowski ground state and proved that it can be written as a thermo-field double state, so that when tracing out over one of the Rindler wedges, we obtain a thermal density matrix with a very precise temperature, i.e. the Unruh temperature.
We close the lecture by making some remarks on the similarities and the challenges we will face to extend this result for the black hole.

Lecture series: Holography lectures by Joan Simon
Before formulating the AdS/CFT, we reviewed the geometry of AdS, both in Poincare patch and global AdS, identified its timelike conformal boundary and its isometries, commenting on how these act geometrically.
We then moved to describe string theory in these backgrounds, stressing the difference between classical string theory and classical "gravity" theory, where the latter only keeps the massless closed string modes.

Building on our previous lecture, we described how to compute density matrices and their matrix elements using euclidean path integrals, reminding ourselves how to compute the partition function at finite temperature.
In the second part of the lecture, we reviewed the geometry of constant proper accelerated observers in special relativity, the appearance of observer dependent horizons and how to choose coordinates describing the so called right and left Rindler wedges. We argued the Hilbert space for a single scalar field in Minkowski factorises into the Hilbert space of the ...

Lecture series: Holography lectures by Joan Simon
We answered the question : what does a thermal state in the CFT correspond to in the gravity theory ?
For thermal states on \mathbb{R}^{1,d}, these correspond to black branes. We computed the bulk thermodynamics, applying the euclidean path integral methods we introduced earlier to these asymptotically AdS configurations.
We then considered thermal states on \mathbb{R}\times S^{d-1}. These correspond to AdS Schwarszchild black hole. When analysing their thermodynamics, we discovered the existence of three different saddle points for a given temperature. We computed the relevant ...

Lecture series: Energy-energy correlations in N=4 SYM
About this lecture series
We shall discuss a particular class of observables, the so-called energy-energy correlations (EEC), which have first been introduced in the context of QCD for the process of electron-positron annihilation into hadrons. We present a new approach to computing energy-energy correlations that exploits their relation to correlation functions and bypasses the use of scattering amplitudes. We illustrate its power by calculating energy-energy correlations in the maximally supersymmetric Yang-Mills theory (N=4 SYM) in the next-to-leading order approximation.

Lecture series: Holography lectures by Joan Simon
We continued our operator-bulk field analysis, by computing the boundary stress tensor in 2d CFTs in terms of bulk geometry defined at the boundary of AdS. We checked our result be deriving the conformal anomaly and reproducing the Brown-Henneaux central charge formula.

Lecture series: Energy-energy correlations in N=4 SYM
About this lecture series
We shall discuss a particular class of observables, the so-called energy-energy correlations (EEC), which have first been introduced in the context of QCD for the process of electron-positron annihilation into hadrons. We present a new approach to computing energy-energy correlations that exploits their relation to correlation functions and bypasses the use of scattering amplitudes. We illustrate its power by calculating energy-energy correlations in the maximally supersymmetric Yang-Mills theory (N=4 SYM) in the next-to-leading order approximation.

We extended Rindler's discussion to the two-sided maximally extended black hole.
We outlined the scattering problem for the black hole formed by gravitational collapse, mentioned the geometric optics approximation used by Hawking to analytically solve the gluing problem to compute the wave functions of the scalar field with the relevant boundary conditions and gave the final answer.
We ended up with a heuristic calculation estimating the time scale for the evaporation of a black hole and the kind of arguments leading Hawking to conclude gravity violates unitarity in ...

Lecture series: Holography lectures by Joan Simon
The partition function plays a key role in QM and QFT to extract different observables. If gravity requires a quantum treatment, how do we compute a gravitational partition function ? More importantly, if black holes are thermal objects, can we compute a partition function that reproduces these results from first principles ?
Following Gibbons and Hawking, we consider a saddle point semiclassical approximation for flat space thermodynamics. After addition of countqerterms, we reproduce the relevant thermodynamics this way. We pointed out important issues such as existence of instabilities or the Hagedorn ...

Lecture series: Holography lectures by Joan Simon
We discussed GR as an effective gauge field theory. This allowed us to
introduce the general principles of EFT
apply them to GR
revisit GR is non-renormalisable
introduce the ADM formalism (hamiltonian formalism)
rederive the hamiltonian in general covariant theories vanishes on-shell, since it generates a gauge symmetry, unless its conjugate vector field does have support at the boundary of your manifold
use such boundary contributions to reproduce the mass and angular momentum conserved charges in GR
