The section carries out research within five major areas:
The areas are described briefly below, and links to the researchers that work with these subjects are provided as well.

Biophysics is the research dealing with the fundamental effects that shape the building blocks of life. With the methods of physics, biophysicists at SDU literally cut to the most fundamental elements of cells when studying, for example, the physical properties of cell membranes such as curvature, stiffness and melting point. By constructing simple models for otherwise highly complicated biological systems, biophysicists can work towards a better understanding of many biological phenomena. They do this both with theoretical mathematical models and in the laboratory. Here, for example, one can examine how the properties of the fat molecules on which cell membranes are constructed depend on whether the fatty acids are saturated or unsaturated, or on their charge. Research in biophysics not only provides insight, but it is also promising for future treatment of diseases and the development of new materials.

The mathematical equations that describe complex physical systems can in many cases not be solved exactly, but most often it is not an obstacle for physicists. Many such problems can be solved numerically using modern computers. SDU hosts one of the strongest supercomputers in the country, Abacus 2.0, and it is used as a tool for research on a wide range of subjects, from particle physics to advanced materials to stellar evolution. For example, computer models can be used to study how a material has different properties at different temperatures. One cannot see from the individual atoms that a material is crystallized, for example, but only by regarding the whole. It is an example of one of many so-called emergenic phenomena that can be investigated with computer simulations.
Particle physics and Cosmology
At the beginning of the universe right after the Big Bang, the universe was quite different than it is today. All matter was pressed together in an almost incomprehensibly small area. Particles that we can only see today in large accelerator systems such as the LHC at CERN were present and interacted with each other and with more common matter through the four fundamental forces: electromagnetism, gravity, the weak and the strong nuclear force. Therefore, the study of the evolution of the universe, cosmology, and of the world's smallest components, particle physics, is completely inextricably linked together, and therefore both subjects are among the most fascinating imaginable.
The research on CP3-Origins (Centre for Cosmology and Particle Physics Phenomenology) illuminates not only the origin and final fate of the universe, but also black holes, neutrinos and dark matter, which are among the least understood phenomena today. Along the way, the actual mathematical structure that all physics uses to describe the universe around us is developed.
Education in Astronomy
The physics programme at SDU includes courses for a specialisation in astronomy. The courses are taught, among others, by Professor Anja C. Andersen, who is known for her research on stardust. With a specialization in astronomy, you’ll get a lot of the same skills as an ordinary physicist. You can also teach astronomy in high school. The training is in line with the research that is going on in cosmology.

Quantum optics is research into how individual light particles, photons, behave, and how to manipulate individual photons. It is one of few branches of particle physics where research can take place in an ordinary laboratory rather than at large-scale facilities such as particle accelerators. At SDU, research in quantum optics is primarily carried out using ultra-cold Rydberg atoms, which makes it possible to write quantum information from individual photons onto atomic states. This field of research is in many ways basic research, but it also has many applications in the technology of the future.
