Graduate teaching

Research students in TCM are able to take advantage of a wide range of courses offered by the University. Final year undergraduate (Part III) courses in both Physics and Mathematics can be relevant. The MPhil in Scientific Computing provide many useful courses (DFT, solid state, scientific programming); the full timetable is available here.

The TCM Group also runs its own graduate lecture programme, mostly in the Michaelmas and Lent Terms, also listed on talks.cam. Some of these lectures have recordings available on our internal site.

Easter 2024

TCM graduate lectures These will take place in person in the TCM Seminar Room, some also with zoom feed.

• Anderson Localisation, Prof. David Khmelnitskii, 10am on various days for eight lectures (30 April; 2, 7, 9, 13, 15, 21 and 23 May).

• Fairy Tales, Prof. David Khmelnitskii, 10am Fridays, six lectures beginning 26 April.

Topics of Current Research:

• Introduction to machine learning in the physical sciences, Christoph Schran, two lectures, 10am on 14 and 16 May. TCM Seminar Room.

• Viscous thermoelectric phenomena in solids, Michele Simoncelli, two lectures, 10am on 27 and 29 May. TCM Seminar Room.
[Non-diffusive, hydrodynamic-like transport of charge or heat has been observed in several materials, and recent, pioneering experiments have suggested the possible emergence of electron-phonon bifluids. Here we introduce the first-principles computational framework to describe these phenomena, showing that the macroscopic viscosity of electrons-phonon bifluids is microscopically determined by composite 'relaxon' electron-phonon excitations, and these also describe electron-phonon drag effects on standard thermoelectric transport coefficients. We demonstrate that these composite excitations emerge from the microscopic coupled electron-phonon Boltzmann transport equation, and show how the latter can be coarse-grained into a set of mesoscopic Viscous Thermoelectric Equations (VTE). The VTE unify the established hydrodynamic equation for electrons derived by Gurzhi [Sov. Phys. Usp. 11 (2) 1968], and the recently developed Viscous Heat Equations for phonons [Phys. Rev. X 10 (2022)], while also covering the mixed electron-phonon bifluid regime. We rely on this framework to quantify phonon-drag effects, and investigate with quantitative first-principles accuracy the emergence of coupled electron-phonon hydrodynamics in several materials, comparing theory with experiments.]

• Continuum mechanics of active matter, Anton Souslov, three lectures, 10am on 3,4,5 June. TCM Seminar Room.
[Abstract: I will focus on the concepts that describe and quantitatively model active materials on the largest scales. Active matter refers to any material in which the constituent particles move themselves by consuming ambient energy. These materials range from biological tissues to artificial systems designed to exhibit exotic mechanical properties. Analogously to how a liquid composed of molecules can be described using the continuum Navier-Stokes equations, fluid-like states of active matter have a hydrodynamic description at the largest scales. Because active matter violates energy conservation (and in some cases, momentum conservation), the equations for the velocity can include terms prohibited in equilibrium, leading to distinct dynamics and instabilities. Analogously, solid-like states of active matter have an elastic description that modifies the classical theory of elasticity in unexpected ways. Finally, I will discuss topics in current research that build on these continuum descriptions, including non-reciprocal interactions, pattern formation, and the role of topology.]

Lent 2024

• Fairy Tales, Prof. David Khmelnitskii, 10am Fridays, nine lectures beginning 19 January. (**No lecture on Friday 1 March.** **Lecture on 8 March by Zoom only**) Lecture notes: Continuous Groups.

Topics of Current Research:

• Field theory approaches to non equilibrium systems, Dr Orazio Scarlatella, two lectures, 10am on Mon 26 Feb and Wed 28 Feb, TCM Seminar Room.
[Abstract: In these lectures I will introduce the Keldysh field theory of non-equilibrium systems. This is an approach to systems that strongly deviate from thermal equilibrium, and is also very successful for problems with quenched disorder. I will first discuss the general formalism and then show some examples of open quantum systems problems and of driven-dissipative problems as commonly arise in quantum optics. If time allows, I will also introduce the Dynamical Mean Field Theory, which is a very successful non-perturbative approach for lattice problems, especially far from equilibrium.]

• Radioastronomy in the SKA era, Dr Daniel Molnar, two lectures, 10am on Tue 12 Mar and Thu 14 Mar, TCM Seminar Room.
[Abstract: I will give a general introduction to the scientific interest behind the 21cm cosmology and its theoretical basis. An overview of the theoretical and instrumentation challenges will also be shown. The current efforts in the Cavendish radio cosmology group will be highlighted in the field of 21cm astronomy and cosmology.]

[Topics: (i) Cohomology and gauge theory. Although we will only touch upon interpretations quickly, these concepts relate to topological gauge theory via Dijkgraaf-Witten constructions, symmetry fractionalisation, and projective symmetry classifications, which were related to the spin liquids by Wen et al. (ii) K-theory and Dirac systems. Here the physical relevance pertains to classification of free fermion systems and even D branes in string theory. (iii) Equivariant K-theory from a combinatorial perspective. Physical relevance pertains to free fermion crystalline phases and those on D branes on toroidal orbifolds.]

Lecture notes

Some of TCM's staff members have produced some particularly illuminating and engaging course notes for courses presented elsewhere. A selection of these is presented below.

Fairy Tales

For over twenty years Prof Khmelnitskii has presented his "Fairy Tales." These are stand-alone lectures elucidating a particular topic of mathematical physics. They are given on Friday mornings at 10am, and many remember them for years. They have been appreciated by many, from PhD students through post-docs to professors.
