Combinatorial QFT, CO 739-002, September 4 - December 2, 2025
12 talks-Collection NumberC25036Quantum field theory intertwines continuous and discrete structures. On the discrete side, combinatorics plays a central role in describing and understanding its expansions and models. This lecture series focuses on the combinatorial aspects of quantum field theory. In the first part, we explore analytic combinatorics techniques, inspired by QFT, for the enumeration of graphs. These methods turn out to be surprisingly powerful in addressing deep questions in algebraic geometry, topology, and statistical models on graphs. In the second part, we turn to discrete structures arising in perturbative expansions of QFT. We study these from a modern combinatorics viewpoint, using tools such as Lorentzian polynomials and generalized permutahedra to better understand the mathematical objects at the heart of quantum field theory.

Structure:
We will discuss 8 papers which had huge impact in physics. One week Instructor Pedro Vieira will discuss a paper; students should read it beforehand. One week later students discuss recent papers referring to that paper (20 min each student, ~ 3 presentations; at the end of the class Pedro will grade the presentations based on “Physics”, “Presentation”, “Question handling”; and give comments).
By the end of the course, students will have explored a vast set of topics in theoretical physics — spotting potential gaps to be fixed — sharpened their presentation skills through steady practice, and sparked cross-disciplinary conversations through our shared physics language.
Familiarity with Quantum Field Theory and General Relativity is assumed.

Quantum Measurement and Continuous Markov Processes Mini-Course, Oct 27 - Nov 28, 2025
3 talks-Collection NumberC25038This series is a crash course introduction to a handful of advanced topics designed to tackle the general problem of how to engineer Positive Operator-Valued Measures (POVMs) using observable building blocks, the so-called Instrument Manifold Program. This program emerged from a recent fundamental breakthrough: how to realize the measurement of a spin’s direction, a.k.a. the spin-coherent-state POVM, a spherical set of outcomes analogous to the well known coherent-state POVM of the standard phase plane.

Holomorphic-topological field theories and representation theory
24 talks-Collection NumberC25031
Holomorphic-topological field theories and representation theory
Holomorphic-topological (HT) field theories form a fascinating class of quantum field theories. These theories combine features of topological quantum field theories (TQFT) and conformal field theories (CFT).Due to the mixed holomorphic-topological nature of such theories, they create interactions between TQFT data (e.g., algbras, monoidal categories, etc) and CFT data (e.g., chiral algebras and chiral categories). This leads to exciting new mathematical structures, and connections to integrable systems, quantum topology and many other areas of mathematics. Recently. much progress has been made on the representation-theoretic aspects of HT theories. Examples include:1. (Shifted) Poisson vertex algebras and their quantizations are constructed from local operators in HT theories.2. Dimensional reduction of 4d HT theories lead to integrable systems and solutions of quantum Yang-Baxter equations.3. 4d N=2 theories are linked to representation theory of K-theoretic Coulomb branches, cluster algebra categorifications, wall crossings and elliptic stable envelops.4. New examples of chiral algebras and their dualities are derived from boundary conditions and dualities of 3d HT theories.Moreover, many interesting TQFTs are given by deformations of holomorphic-topological theories. Examples include topological twists of 3d N=4 and 4d N=2 theories. These theories have attracted considerable attention in recent years for their connections to 3d mirror symmetry and the Langlands program. Some of these TQFTs only admit Lagrangian descriptions as HT QFTs, and therefore studying HT theories offers a possible approach for understanding these non-Lagrangian TQFTs.This conference will focus on the representation-theoretic aspects of HT theories, particularly:1. Chiral algebras arising from observables of HT QFT.2. Quantum algebras, including Yangians and quantum affine algebras, and their relation to HT theories.3. Chiral categories and OPE of line operators in HT theories.4. Deformation of HT theories and their relation to chiral algebra deformations.5. Relation between various HT theories under dimensional-reduction.We aim to bring together leading mathematicians and physicists, to inform each other about the recent progress made in this area.:: :: ::

100 Years of Quantum: Perspectives on its Past, Present, and Future
32 talks-Collection NumberC25026
In July 1925, Heisenberg published his paper on matrix mechanics, followed shortly thereafter (in early 1926) by Schrodinger’s paper on wave mechanics. As such, 2025 is the centenary of the modern quantum theory. This conference aims to bring together experts in the history and philosophy of quantum theory and researchers working on various foundational issues to shed new light on the past, present and future of the theory.
The meeting aims to benefit from the useful synergy that exists between historical studies and efforts to push forward the frontier of our knowledge. On one side, the details of the path to discovery of various quantum concepts or applications of quantum ideas can inform contemporary research. For instance, whenever there is a paradigm of thinking that is sufficiently pervasive today that it is difficult to even recognize the possibility of alternatives, familiarity with the debates at the historical origin of this paradigm can help to make explicit what is usually left implicit. On the other side, modern developments can often shed new light on various historical and philosophical issues.
The fact that there is still no broad consensus on many of the conceptual issues that have been controversial since the birth of modern quantum theory suggests that a proper understanding of these remains to be achieved. The occasion of the quantum centenary provides a good opportunity for the community to develop a broader perspective on these issues, draw connections between research programs that aim to address them, and set objectives for future research.
The aim is to have two types of talks concerning the history: those that present novel takes on well-studied historical topics and those that address more unconventional historical questions. The second category aims to include talks on the history of a variety of subfields of quantum theory, such quantum information, quantum field theory, quantum optics, quantum logic, quantum chemistry, quantum gravity, quantum matter and quantum foundations..
Conference topics include:
- The prehistory of modern quantum theory
- The historical development of modern quantum theory
- The discovery of Important concepts in quantum theory (the uncertainty principle, wave-particle duality, particle statistics, the no-cloning theorem, teleportation, etc.)
- The discovery of important no-go results (von Neumann’s no-go theorem, the 1935 Einstein-Podolsky-Rosen argument, Bell’s theorem, the Kochen-Specker theorem)
- The history of quantum information, quantum field theory, quantum optics, quantum logic, quantum chemistry, quantum gravity, and quantum matter
- The sociology of quantum physics
The conference will include invited as well as contributed talks.:: :: ::

Introduction to Categorical Probability Mini-Course, Oct 1-7, 2025
4 talks-Collection NumberC25054In the last few years, a new perspective on probabilistic reasoning has been extensively developed with the help of tools from category theory. The idea is to shift focus from the measure-theoretic details to structural properties of information flow in the presence of uncertainty - independence, conditioning, nested uncertainty, etc. This shift allows one to reason without the need to specify a concrete model of uncertainty, be it discrete, continuous, Gaussian, possibilistic or one of many other instantiations. In this course I will present a high-level overview of the leading approach to categorical probability that is based on so-called Markov categories. We will focus on the diagrammatic language of Markov categories that can be understood without any knowledge of category theory. Using such diagrams, we can also express basic concepts that have been useful in proving a plethora of categorical versions of classical theorems - strong law of large numbers, de Finetti's theorem, d-separation criterion for Bayesian networks, ergodic decomposition theorem, zero/one laws and others.
