Andreas Bill
Ph.D. (Dr.rer.nat.), University of Stuttgart, Germany, 1995 Location: California State University, Long Beach Phone: (562) 985-8616 Office Webpage : http://www.physics.csulb.edu/~abill/ Research Interest: Condensed Matter Physics is concerned with the study of physical properties of matter in solid or liquid phases. The challenge is to describe both micro- and macroscopic properties of an enormous number of particles strongly interacting with each other. The main subfield of condensed matter physics deals with crystalline solids. Among the many unresolved issues in solid state physics emphasis has been set in recent years on two fundamental topics: 1) The effect of correlations resulting from the strong Coulomb interaction between electrons on physical properties of materials such as heavy fermions, high-temperature superconductors, low-dimensional electron systems; 2) The competition between different states of matter such as superconductivity and magnetism or ferroelectricity. Both issues require a quantum description of matter. My research discusses various theoretical aspects of the two above questions focusing on one class of systems: layered materials. These include high-temperature and organic superconductors, halide nitrides, diverse intercalated materials, as well as artificially tailored heterogeneous nanostructures. Such systems allow bridging the worlds of one-, two- and three-dimensional physics. Layered materials are simple enough for problems to be treated with modern theoretical methods, yet complicated enough to disclose unconventional effects and allow the emergence of new states of matter. Not only does this research address fundamental issues of condensed matter physics, it also invites for the development of new applications and technologies. |
