Standard Model (Elective), PHYS 622, January 5 - February 6, 2026
13 talks-Collection NumberC25050The course will give introduction into the structure of the Standard Model of particle physics and its field content. The emphasis will be made on the underlying principles, such as gauge invariance, cancellation of quantum anomalies, and Brout-Englert-Higgs mechanism. Effective low-energy description of strong interactions will be also discussed. It will be assumed that students are familiar with the basics of quantum field theory.

Topics include an introduction to Python, linear algebra, Monte Carlo methods, root finding, integration, differential equations, and are based on applications by researchers at Perimeter. The course will also teach principles of software engineering ensuring reproducible results.

Gravitational Physics (Elective), PHYS 636, January 5 - February 6, 2026
13 talks-Collection NumberC25051We will study advanced topics in gravitational physics and their applications to high energy physics. After reviewing topics in differential geometry, including differential forms, Cartan's formalism, and the Gauss-Codazzi equations for the geometry of embedded hypersurfaces, we will address the Einstein-Hilbert variational principle and the Hawking-York term, which plays an important role in the gravitational path integral. We will then study the Kerr solution for rotating black holes, and address topics in black hole thermodynamics using the Euclidean action, as well as Hawking radiation. Time allowing we will touch on some more advanced topics such as domain walls, brane world scenarios, Kaluza-Klein (KK) theory & KK black holes, Gregory-Laflamme instability, and Gravitational instantons.

Mathematical Physics I (Core), PHYS 777-004, January 5 - February 6, 2026
12 talks-Collection NumberC25049We will study topics in theoretical physics through the lens of differential geometry and algebraic topology. The topics will be chosen among the following: differential forms on manifolds, homology, homotopy, de Rham cohomology, gauge theory and principal fiber bundles, nonperturbative effects and topology, characteristic classes, basics of solitons (ex: why is the instanton number a number?), index theorems, introduction to anomalies.

Quantum Foundations (Elective), PHYS 639, January 5 - February 6, 2026
13 talks-Collection NumberC25052This course will explain why textbook quantum “theory” is merely a mathematical recipe rather than a proper physical theory. It will then cover the most serious obstacles to fixing this problem and to providing a clear metaphysics underpinning the mathematics of quantum theory. We will focus on key no-go theorems (e.g., Bell’s theorem, contextuality theorems, and Extended Wigner’s friend arguments), as well as on key frameworks (e.g., generalized probabilistic theories and ontological models).
-
Relativity (Core), PHYS 604, November 11 - December, 12 2025
13 talks-Collection NumberC25044This course offers an introduction to general relativity (GR), focusing on the core principles of Einstein's theory of gravity. We will explore key topics such as the equivalence principle, some essential concepts in differential geometry, the Einstein-Hilbert action, and Einstein's field equations. Furthermore, we will examine practical applications of general relativity in understanding black holes, cosmology, and gravitational waves.
-
Quantum Field Theory II (Core), PHYS 603, November 11 - December 12, 2025
14 talks-Collection NumberC25045This course introduces the functional integral formalism, the renormalization group, and non-abelian gauge theory. Additional topics may be covered as time allows.

Combinatorial QFT, CO 739-002, September 4 - December 2, 2025
18 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.

Beautiful Papers, PHYS 773, September 12 - December 1, 2025
15 talks-Collection NumberC25046Scroll down to Registration and Enrollment to participate.
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.
The papers:
Sept 12 & 19: On the Quantum Correction for Thermodynamic Equilibrium, Wigner, 1932 Topic: Quantum Mechanics
Sept 22 & 29: Existence theorem for certain systems of nonlinear PDEs, Foures-Bruhat, 1952 Topic: General relativity
Oct 3 & 10: The Renormalization Group and the Epsilon Expansion, Wilson and Kogut, 1973 Topic: Quantum Field Theory
Oct 10 (EXTRA) & 17: More about the Massive Schwinger Model, Coleman, 1976 Topic: 2D Quantum Field Theory

Quantum Measurement and Continuous Markov Processes Mini-Course, Oct 27 - Dec 11, 2025
11 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.
Outline: Oct 27: Introduction: The Planimeter and the "Spherimeter'' Oct 30: The Planimeter and the "Spherimeter'' Nov 03: CANCELLED Nov 06: Indirect Measurement and System-Meter Interaction Nov 10: POVMs and Decoherence Nov 13: POVMs and Decoherence Nov 17: CANCELLED Generalized Observables: Phase-Point and Spin-Direction Nov 20: Classical Measuring Instruments Nov 24: Generalized Observables: Phase-Point and Spin-Direction Nov 27: Generalized Observables: Phase-Point and Spin-Direction Dec 01: CANCELLED Frame Operators and Quasi-Probability Distributions Dec 04: Frame Operators and Quasi-Probability Distributions Dec 08: The Arthurs-Kelly (1965) and D’Ariano (2002) Measurements Dec 11: The Arthurs-Kelly (1965) and D’Ariano (2002) Measurements
