DATE: 08 January 2018, 16:00 to 17:30 VENUE: Ramanujan Lecture Hall, ICTS Bangalore Lecture 1: 8 January 2018, 16:00 to 17:30 Title: Symmetries, Duality, and the Unity of Physics Abstract: Global symmetries and gauge symmetries have played a crucial role in physics. The idea of duality demonstrates that gauge symmetries can be emergent and might not be fundamental. During the past decades, it became clear that the circle of ideas about emergent gauge symmetries and duality is central in different branches of physics including Condensed Matter Physics, Quantum Field Theory, and Quantum Gravity. We will review these developments, which highlight the unity of physics. Lecture 2: 9 January 2018, 16:00 to 17:30 Lecture 3: 11 January 2018, 11:00 to 12:30 Lecture 4: 12 January 2018, 11:00 to 12:30 Title: (Lectures 2 - 4) Dynamics of 2+1-dimensional Quantum Field Theory Abstract: (Lectures 2 - 4) We will review recent advances in the study of the dynamics of 2+1-dimensional quantum field theories. There will be special emphasis on the role of symmetries, topology, and duality.
