Prospective students

Research

We provide Bachelor, Master, and Doctoral theses topics at the interface between mathematics and physics. Possible research topics include, but are not limited to, constructive quantum field theories, conformal field theory, random geometry, supersymmetric gauge theories and fractals. If you are interested in one of our research topics, please feel free to contact Kalle Kytölä, Eveliina Peltola, or Oscar Kivinen.

We also provide Summer Internships for outstanding students. These are advertised in the department's website.

Teaching

You are also welcome to take part in any of our lecture courses related to mathematical physics.

21.10. 10:15 Prof. Christian Webb (University of Helsinki): Fractional charge correlation functions in the sine-Gordon model and twisted fermions – M3 (M234)
The sine-Gordon model is a fascinating model of two-dimensional quantum field theory. It is not a conformal field theory, but it is believed to enjoy many interesting properties. This talk will focus on one of these properties known as bosonization. I will discuss how at the so-called free fermion point of the model, certain correlation functions of the sine-Gordon model are tau functions related to two-dimensional Dirac operators with twisting. This talk is based on joint work with Roland Bauerschmidt and Scott Mason.
