Description of mini-courses

 

Mini-course 1: Operator Algebras and the Formulation of Quantum Field Theory

Professor: João Carlos Alves Barata (USP)
Youtube videos: https://www.youtube.com/playlist?list=PLukZFARoEvIYexXPb2ukBuzJCkYQf_YQU 

• This course provides an overview of the mathematical challenges associated with formulating Quantum Field Theories (QFT) and explore the applicability of concepts from Operator Algebras in this context. Key principles of C*-algebras and von Neumann algebras will be introduced for a physicist audience, highlighting their role in the mathematical description of quantum fields. Additionally, we will discuss some more recent findings and their significance.

•  Prerequisites: Some background knowledge in QFT and assumed, and the lecturer will introduce the required mathematical ideas as they become necessary. It will be a mini-course for theoretical physicists with interest in mathematical ideas.

Lectures 1-3

 

Mini-course 2 (in English): Introduction to black hole Thermodynamics

Professor: Pietro Benetti Genolini (Université de Genève)

Youtube videos: https://www.youtube.com/playlist?list=PLukZFARoEvIZv3FUtZmx1JY82fUuGjvLs 

 

• This course provides a concise and biased introduction to black hole thermodynamics. It covers the laws of black hole mechanics, Hawking radiation, Euclidean quantum gravity methods, and AdS black holes.
• Prerequisites: first notions on GR, possibly including the definition of AdS space, and general features of the Schwarzschild solution, knowing that black holes can be charged and rotating.
  
  

Lecture notes

 

Mini-course 3 (in English): Knots and Quantum Mechanics

Professor: Dmitry Melnikov (IIP-UFRN) 
Youtube videos: https://www.youtube.com/playlist?list=PLukZFARoEvIYpC3Sk372a06GCnxX3Xb1t

• This course provides a basic introduction to knot theory and topological quantum field theories (TQFTs). The lecturer will demonstrate how to compute fundamental topological invariants and discuss their connections to observables in quantum mechanics and quantum field theory. This interplay offers a valuable framework for exploring foundational concepts in quantum mechanics, such as quantum entanglement. It will be illustrated how quantum entanglement can be encoded in the topology of emergent spaces and the lecturer will present a few applications, including the classification of entanglement types and the development of basic quantum algorithms.
• Prerequisites: this set of lectures is aimed at graduate students and advanced undergraduate students, familiar with the basic concepts of quantum mechanics and linear algebra. Basic familiarity with group theory and representation of groups, as well as the notion of path integral is useful, but not strictly necessary.
• Preparatory material:

Mini-course 4: Introduction to Integrable Models

Professor: José Francisco Gomes (IFT-UNESP)
Youtube videos: https://www.youtube.com/playlist?list=PLukZFARoEvIZzTbNz_v6xLbHmn71ERsZ4

 

• Lecture 1: Lie Algebras and Symmetry

  a) SU(2) and angular momentum as a prototype of general finite-dimensional Lie algebras
  b) SU(3) and its applications to particle physics (quark model)
  c) Overview of general finite-dimensional Lie algebras

  Lecture 2: Infinite-Dimensional Algebras and Conformal Invariance

  b) Conformal invariance: correlation functions, critical exponents, and representations of the Virasoro algebra

  Lecture 3: Integrable Models

  a) Introduction to integrable models: construction and classification
  b) Construction of soliton solutions

History

The School of Physics Roberto A. Salmeron (EFRAS) is a national-level school dedicated to the complementary training of undergraduate and graduate students, which in each edition seeks to enhance its internationalization. Its program includes mini-courses on current topics in Physics, lectures, panel discussions, and presentations of submitted works in the form of oral presentations and posters, providing an appropriate environment for student training as well as interaction with Brazilian and international professors and students. The school is promoted by the International Center of Physics and the Institute of Physics at UnB and has been held continuously since 2012. 

 

The name EFRAS is a tribute to one of the founding professors of the Institute of Physics at the University of Brasília (IF-UnB) - Prof. Roberto A.
