Quantum Foundations (2022/2023)
13 talksCollection NumberC23007This course will cover the basics of Quantum Foundations under three main headings. Part I – Novel effects in Quantum Theory. A number of interesting quantum effects will be considered. (a) Interferometers: MachZehnder interferometer, ElitzurVaidman bomb tester, (b) The quantumZeno effect. (c) The no cloning theorem. (d) Quantum optics (single mode). HongOuMandel dip. Part II Conceptual and interpretational issues. (a) Axioms for quantum theory for pure states. (b) VonNeumann measurement model. * (c) The measurement (or reality) problem. (d) EPR Einstein’s 1927 remarks, the EinsteinPodolskyRosen argument. (e) Bell’s theorem, nonlocality without inequalities. The Tirolson bound. (f) The KochenSpecker theorem and related work by Spekkens (g) On the reality of the wavefunction: Epistemic versus ontic interpretations of the wavefunction and the PuseyBarrettRudolph theorem proving the reality of the wave function. (h) Gleason’s theorem. (i) Interpretations. The landscape of interpretations of quantum theory (the Harrigen Spekkens classification). The de BroglieBohm interpretation, the many worlds interpretation, wavefunction collapse models, the Copenhagen interpretation, and QBism. Part III Structural issues. (a) Reformulating quantum theory: I will look at some reformulations of quantum theory and consider the light they throw on the structure of quantum theory. These may include time symmetric quantum theory and weak measurements (Aharonov et al), quantum Bayesian networks, and the operator tensor formalism. (b) Generalised probability theories: These are more general frameworks for probabilistic theories which admit classical and quantum as special cases. (c) Reasonable principles for quantum theory: I will review some of the recent work on reconstructing quantum theory from simple principles. (d) Indefinite causal structure and indefinite causal order. Finally I will conclude by looking at (i) the close link between quantum foundations and quantum information and (ii) possible future directions in quantum gravity motivated by ideas from quantum foundations.

Mathematical Physics (2022/2023)
12 talksCollection NumberC23004This course will cover the mathematical structure underlying classical gauge theory. Previous knowledge of differential geometry is not required. Topics covered in the course include: introduction to manifolds, symplectic manifolds, introduction to Lie groups and Lie algebras; deformation quantisation and geometric quantisation; the matematical structure of field theories; scalar field theory; geometric picture of YangMills theory; symplectic reduction. If time permits, we may also look at the description of gauge theory in terms of principal bundles and the topological aspects of gauge theory. 
Gravitational Physics (2022/2023)
14 talksCollection NumberC23006The main objective of this course is to discuss some advanced topics in gravitational physics and its applications to high energy physics. Necessary mathematical tools will be introduced on the way. These mathematical tools will include a review of differential geometry (tensors, forms, Lie derivative), vielbeins and Cartan’s formalism, hypersurfaces, GaussCodazzi formalism, and variational principles (EinsteinHilbert action & GibbonsHawking term). Several topics in black hole physics including the Kerr solution, black hole astrophysics, higherdimensional black holes, black hole thermodynamics, Euclidean action, and Hawking radiation will be covered. Additional advanced topics will include domain walls, brane world scenarios, KaluzaKlein theory and KK black holes, GregoryLaflamme instability, and gravitational instantons

Numerical Methods (2022/2023)
12 talksCollection NumberC23003This course teaches basic numerical methods that are widely used across many fields of physics. The course is based on the Julia programming language. Topics include an introduction to Julia, linear algebra, Monte Carlo methods, differential equations, and are based on applications by researchers at Perimeter. The course will also teach principles of software engineering ensuring reproducible results. 
Statistical Physics (2022/2023)
14 talksCollection NumberC22038The course begins by discussing several topics in equilibrium statistical physics including phase transitions and the renormalization group. The second part of the course covers nonequilibrium statistical physics including kinetics of aggregation, spin dynamics, population dynamics, and complex networks.

Quantum Field Theory II (2022/2023)
14 talksCollection NumberC22037The course has three parts. In the first part of the course, the path integral formulation of nonrelativistic quantum mechanics and the functional integral formulation of quantum field theory are developed. The second part of the course covers renormalization and the renormalization group. Finally, nonabelian gauge theories are quantized using functional integral techniques.

Special Topics in Physics  QFT2: Quantum Electrodynamics (Cliff Burgess)
12 talksCollection NumberC22043This course uses quantum electrodynamics (QED) as a vehicle for covering several more advanced topics within quantum field theory, and so is aimed at graduate students that already have had an introductory course on quantum field theory. Among the topics hoped to be covered are: gauge invariance for massless spin1 particles from special relativity and quantum mechanics; Ward identities; photon scattering and loops; UV and IR divergences and why they are handled differently; effective theories and the renormalization group; anomalies.

Relativity (2022/2023)
14 talksCollection NumberC22041This is an introductory course on general relativity (GR). We shall cover the basics of differential geometry and its applications to Einstein’s theory of gravity. The plan is to discuss black holes, gravitational waves, and observational evidence for GR, as well as to cover some of the more advanced topics. 
Quantum Field Theory I (2022/2023)
14 talksCollection NumberC22036The course starts by looking for a quantum theory that is compatible with special relativity, without assuming fields are fundamental. Nevertheless fields turn out to be a very good, maybe inevitable mathematical tool for formulating and studying such a relativistic quantum theory. The second part of the course introduces the Dirac theory and canonically quantizes it. It also quantizes the Maxwell field theory. The Feynman diagram technique for perturbation theory is developed and applied to the scattering of relativistic fermions and photons. Renormalization of quantum electrodynamics is done to oneloop order.
Prerequisite: PSI Quantum Theory course or equivalently Graduate level Quantum Mechanics and QFT of scalar theory

Quantum Theory (20222023)
14 talksCollection NumberC22035This course on quantum mechanics is divided in two parts:
The aim of the first part is to review the basis of quantum mechanics. The course aims to provide an overview of the perturbation theory to handle perturbations in quantum systems. Time evolution of quantum systems using the Schrodinger, Heisenberg and interaction pictures will be covered. Basics of quantum statistical mechanics for distinguishable particles, bosons, and fermions will be covered. A brief overview of density matrix approach and quantum systems interacting with the environment will be given.
The second part of the course is an introduction to scalar quantum field theory. The Feynman diagram technique for perturbation theory is developed and applied to the scattering of relativistic particles. Renormalization is briefly discussed. 
Classical Physics (2022/2023)
14 talksCollection NumberC22039This is a theoretical physics course that aims to review the basics of theoretical mechanics, special relativity and classical field theory, with the emphasis on geometrical notions and relativistic formalism.

Machine Learning (2021/2022)
14 talksCollection NumberC22023This course is designed to introduce modern machine learning techniques for studying classical and quantum manybody problems encountered in condensed matter, quantum information, and related fields of physics. Lectures will focus on introducing machine learning algorithms and discussing how they can be applied to solve problem in statistical physics. Tutorials and homework assignments will concentrate on developing programming skills to study the problems presented in lecture.
