# Professor Jan Philip Solovej receives ERC grant

Professor in mathematics Jan Philip Solovej from Department of Mathematical Sciences, University of Copenhagen has passed the competitive selection and receives a 5-year *advanced grant* from The European Research Council (ERC) at a total of 1.5 million Euros. These grants are solely given to exceptional established research leaders to pursue ground-breaking, high-risk projects.

With this grant Professor Solovej will be able to consolidate his position as one of the internationally leading researchers within the area of mathematical physics. His research is on the boundary between mathematics and physics, and the project named *The Mathematics of the Structure of Matter* will involve mathematicians and physicists from around the world.

The project aims at analysing and developing the mathematical models used in physics for describing matter and its structure. It revolves around uncovering to what extend these models explains fundamental characteristics of matter in general. The project has as a point of departure the question on whether mathematical models used at the microscopic level for describing characteristics of atoms also can be used for describing characteristics of macroscopic matter. The answer to these questions might be one of the keys to understanding why macroscopic matter is stable. In order to answer this question Professor Solovej and his colleagues will have to study models of matter on all scales: from the microscopic subatomic level to the macroscopic level of the structure of giant stars.

The project differs from theoretical physics by its point of departure in the mathematical models, which will be further developed without necessarily paying attention to the physical relevance. Philosophically this gives the advantage of not letting the development be restricted by reality, and this method has nevertheless often demonstrated how a theoretical mathematical model subsequently has proved useful in describing physical phenomena very accurately. This is for example true in the study of systems in 1 or 2 dimensions which was previously regarded as a mathematical curiosity, but is now studied in laboratories all over the world.

In the evaluation of the project, the panel emphasizes that Professor Solovej has made ”groundbreaking contributions in Mathematical Physics”; this is amplified by one of the reviewers noting that Professor Solovej ”combines deep physical insights with outstanding mathematical techniques to achieve his results”. All in all an evaluation that makes no secret of Professor Solovej as an extremely skilled mathematician, who with this research project is expected to have major influence on the physical comprehension of matter.

Professor Solovej became in 1985 cand.scient from University of Copenhagen and in 1989 PhD from Princeton University in USA, where he later also was employed as assistant professor. He has spent more than 10 years researching at different universities in USA. He became professor at Aarhus University prior to his employment at University of Copenhagen in 1997.

In addition to being a highly appreciated colleague and teacher Professor Solovej is also deeply involved in several leading administrative posts including vice chairman in *Danish Mathematical Society*, secretary of* The International Association of Mathematical Physics* and newly appointed head of *The Danish Council for Independent Research – Natural Sciences*. Professor Solovej is especially proud of the 2001 award for being *Teacher of the Year* at University of Copenhagen. An award that is undoubtedly is the result of his great commitment, his well-preparedness, and his ability to visualize mathematics as relevant for students from many fields.
