Assistant Professor of Mathematical Physics, Radboud University Nijmegen

Are you an enthusiastic mathematical physicist or mathematician with a strong and broad interest in the philosophical foundations of physics? Then this exciting opportunity to join our institute as an assistant professor could be interesting for you.

Your primary place of employment will be the Department of Mathematics at the Institute for Mathematics, Astrophysics, and Particle Physics (IMAPP) of Radboud University. You will also be a member of the new Radboud Center for Natural Philosophy (RCNP), created by 2022 Spinoza laureate Klaas Landsman, where you can exchange ideas with mathematical physicists, theoretical physicists, philosophers of science, and historians of science. The other partners in this Center, besides IMAPP, are the Institute for Science in Society (ISiS) in the Faculty of Science and the Center for the History of Philosophy and Science (CHPS) in the Faculty of Philosophy, Theology and Religious Studies. You should therefore be willing and able to work in an interdisciplinary team and collaborate with both natural scientists and humanities scholars. RCNP’s initial research focus will be on determinism, randomness and emergence in modern physics. Your expertise should be in at least one and ideally more of the three great fundamental theories of modern physics, viz. statistical mechanics, quantum field theory, and general relativity. Expertise in the foundations of mathematics and logic would be a plus.

As Assistant Professor of Mathematical Physics, you will teach general mathematics and mathematical physics courses to mathematics and physics students at both BSc and MSc level. In addition, you will develop and teach specialised courses within the domain of the Radboud Center for Natural Philosophy, often jointly with colleagues from relevant neighbouring disciplines. On average, the teaching load will be 40% (20% in the first three years), with 40% research time (to be dedicated to high-quality, internationally visible research), and 20% management and outreach activities. You will supervise or co-supervise BSc, MSc and PhD students writing their theses. You will be expected to publish in reputable international journals and attract external research funding from governmental, European and/or private institutions. Moreover, you will build or at least contribute to appropriate international networks.

PhD position in Nijmegen

PhD Candidate in Analysis and Geometry on Manifolds and Related Areas

The Department of Mathematics is seeking a highly motivated PhD candidate for a research position funded by the NWO ENW-M project ‘Symmetry and analytic torsion’. This project is about developing and applying a version of analytic torsion incorporating group actions. It falls in the broad area of analysis and geometry on manifolds. There are links with index theory, noncommutative geometry and group and representation theory. The PhD project will be supervised by Dr Peter Hochs
We will support you through the PhD process to engage in excellent research, participate in international meetings and develop teaching skills that will equip you for a career in either academia or industry.  This position has a light teaching load, of up to 10% of your working time. Upon successful completion, you will be awarded a PhD from Radboud University.

We welcome applications from candidates with an excellent academic track record, and demonstrable experience in at least one of the areas mentioned above. Members from groups that are underrepresented in Science, Technology, Engineering and Mathematics disciplines are particularly encouraged to apply.

Deadline: 17 November 2022

Assistant/Associate Professor of Mathematical Physics, Radboud University Nijmegen

We are looking for a mathematician working in the area of mathematical general relativity. This position will expand our young initiative in mathematical relativity, which is part of the Mathematical Physics research group. This group has traditionally specialised in quantum (field) theory, non-commutative geometry and operator algebras, and foundations of quantum physics and general relativity, which is led by Klaas Landsman and Walter van Suijlekom as full professors and also includes Annegret Burtscher, Peter Hochs, and Michael Müger. Within the Mathematics Department, this group is also closely connected to research in both applied mathematics, especially on partial differential equations (PDEs), and pure mathematics with a focus on analysis and geometry. You will also strengthen the increasing concentration of our umbrella institute (IMAPP) on gravity as a key research theme, particularly on black holes (including the Event Horizon Telescope), gravitational waves (with links to both current and future detection technology such as the Einstein Telescope), and quantum gravity. Women and members of other groups underrepresented in science are especially encouraged to apply.

Cyclic Cohomology at 40: Online conference

September 27 – October 1, 2021, The Fields Institute (online)

The year 2021 will mark the 40th anniversary of the discovery and development of Cyclic Cohomology Theory by Alain Connes. Its further flourishing fostered by many mathematicians including Dan Quillen, Jean Louis Loday, Boris Tsygan, Boris Feigin, Joachim Cuntz, Ib Madsen, Max Karoubi, and many others has brought a remarkable development of the subject in many distinct directions, in particular in global analysis, representation theory and index theory, algebraic K-theory and cyclotomic trace maps, arithmetic geometry and mathematical physics. The goal of this meeting will be to bring top experts from around the world to lecture on the state of the art in the field, to look towards the future and discuss the most pressing current open problems in the field.

Organizing Committee

Alain Connes – Collège de France and Institut des Hautes Études Scientifiques Caterina Consani – Johns Hopkins University Masoud Khalkhali – Western University Henri Moscovici – The Ohio State University

New Master track Mathematical Physics in Nijmegen

Radboud University Nijmegen offers a new master track Mathematical Physics, preparing you for research in noncommutative geometry, quantum theory and/or mathematical general relativity.

The Mathematical Physics core track of the Master’s specialisation in Mathematics will bring you up-to-date in modern mathematical physics, and prepares you for research in one (or both) of the two great fundamental theories of physics, namely general relativity and quantum (field) theory.

The mathematical topics covered in this track also make sense as pure mathematics and are already very exciting as such – our interest lies both there, supported by our colleagues in pure and applied mathematics, and in applications to the frontiers of fundamental physics. In the latter direction, you may want to profit from the neighboring departments of astrophysics and high-energy physics, which offer their own Master’s specialisation in Particle and Astrophysics, from which you may take some electives. In any case, in mathematics you can choose from a wide range of courses specific to this track:

  • General background for all of Mathematical Physics: Differential Geometry, Symplectic Geometry, Lie Groups, Lie Algebras, Functional Analysis, Partial Differential Equations
  • Mathematical General Relativity: Calculus of Variations, Nonlinear Wave Equations, Singularities and Black Holes
  • Quantum (Field) Theory: Poisson Geometry, Non-commutative Geometry, Operator Algebras, Quantum Computing, Quantum Information Theory

Writing your Master’s thesis allows you to specialise in a specific area based on your interests. The thesis is supervised by a staff member at the Mathematics department and can be combined with an internship. The Mathematics department has a well-established group in Mathematics physics.

Curriculum and courses

Please refer to the online course guide for further information about the study program.
