Twisted Holography MiniCourse
5 talksCollection Number C23050This minicourse will introduce twisted holography, which is holography for BPS subsectors of gauge theory and gravity. We will start by introducing the Bmodel topological string from the spacetime perspective, before discussing branes, backreaction, and the holographic duality.

Quantum Spectral Curve and Three Point Functions minicourse
5 talksCollection Number C23049In this minicourse we will describe some recent integrability developments in N=4 SYM. Pedro will start with some overview of three point functions in this theory. Paul will introduce the powerful Quantum Spectral Curve formalism describing the full planar spectrum of N=4 SYM starting with some elementary spin chain introduction. In this formalism, each operator in the theory is governed by a (set of) Qfunction(s). In his last lecture Paul will walk us through an explicit example from beginning to end of a QSC solution. Pedro will then describe some explorations on three point correlation functions in this theory. The goal would be to have a machine where three Qfunctions are given as input and a threepoint function is spit out as output. We will describe where we are in this quest.
No Zoom link or hybrid participation available. Registration is not required.



Topological Quantum Field Theories  minicourse
8 talksCollection Number C23048A quantum field theory is deemed topological if it exhibits the remarkable property of being independent of any background metric. In contrast to most other types of quantum field theories, topological quantum field theories possess a welldefined mathematical framework, tracing its roots back to the pioneering work of Atiyah in 1988. The mathematical tools employed to define and study topological quantum field theories encompass concepts from category theory, homotopy theory, topology, and algebra.
In this course, we will delve into the mathematical foundations of this field, explore examples and classification results, especially in lower dimensions. Subsequently, we will explore more advanced aspects, such as invertible theories, defects, the cobordism hypothesis, or state sum models in dimensions 3 and 4 (including TuraevViro and DouglasReutter models), depending on the interests of the audience.
Today, the mathematics of topological quantum field theories has found numerous applications in physics. Recent applications include the study of anomalies, noninvertible symmetries, the classification of topological phases of matter, and lattice models. The course aims to provide the necessary background for understanding these applications. 
General Relativity for Cosmology
21 talksCollection Number C23040This is an advanced graduate course which develops the math and physics of general relativity from scratch up to the highest level. The going will sometimes be steep but I try to be always careful. The purpose is to prepare for studies in quantum gravity, relativistic quantum information, black hole physics and cosmology. Quick summary of the contents:  Coordinatefree Differential Geometry, Weyl versus Ricci curvature versus Torsion, Vielbein Formalism, Spinconnections, Formvalued Tensors, Spectral Geometry, some Cohomology.  Derivations of General Relativity including as a Gauge Theory, Diffeomorphism Invariance vs. Symmetries, Bianchi Identities vs. Local and Global Conservation Laws.  Penrose Diagrams for Black Holes and Cosmology, Types of Horizons, Energy Conditions and Singularity theorems, Properties and Classification of Exact Solutions.  Cosmology and Models of Cosmic Inflation 


Mathematical Physics  Elective (2022/2023)
13 talksCollection Number C23027Title: An introduction to twistors Course Description: Twistor theory, introduced by Penrose many years ago, is a way to reformulate massless fields on fourdimensional spacetime in terms of an auxiliary 6dimensional complex manifold, called twistor space. This course will introduce twistor space and the Penrose correspondence (relating fields on twistor space and spacetime), at both classical and quantum levels. We will discuss the twistor realization of selfdual YangMills theory and of selfdual gravity. If time permits we will discuss the connection between twistors and celestial holography.

Quantum Matter (2022/2023)
13 talksCollection Number C23024Matter is quantum. Growing experimental results on materials, natural and synthetic (ion traps, cold atoms etc.,) and concomitant theoretical developments make `quantum matter' an exciting field. There is also a growing interplay of quantum matter physics and quantum information/computation. With a focus on concepts I plan to discuss key phenomenology, quantum models and theory. 
AdS/CFT (2022/2023)
13 talksCollection Number C23026We will cover the basics of the gauge/gravity duality, including some of the following aspects: holographic fluids, applications to condensed matter systems, entanglement entropy, and recent advances in understanding the black hole information paradox.
