The three main research areas of the Laboratory of Physics are Aerosol Physics , Computational Physics, and Optics. The research is related to a wide range of fields, including optics and biophotonics, environmental sciences, biological and biomedical sciences, high-temperature superconductors and molecular electronics, as well as phase change materials used in consumer products. The Unit’s objective is to balance basic and industrially applicable research, and both are now performed with excellence in each of the three research areas.
The Aerosol Physics Unit is loosely organized into two groups that share equipment and researchers. The Instrumentation and Emissions Group (Prof. Jorma Keskinen) develops aerosol measurement methods and studies emission and atmospheric aerosols.The Aerosol Synthesis Group (Prof. Jyrki Mäkelä) uses thermal synthesis methods to produce single and multicomponent nanoparticles and to develop nanostructured functional coatings.
The Computational Physics Unit hosts five groups: Biological Physics Group (Prof. Ilpo Vattulainen), Spectroscopies of Complex Materials Group (Dr. Matti Lindroos), Materials and Molecular Modeling (Prof. Jaakko Akola), Electronic Structure Theory Group (Prof. Tapio Rantala) and Quantum Control and Dynamics Group (Prof. Esa Räsänen). All fields of the unit interact with one another through the development and applications of novel methodology that ranges from quantum-mechanical ab-initio techniques to density functional theories and atomistic simulations as well as particle-based coarse-grained methods.
The Optics Laboratory is organized into three groups that share laboratory space and equipment, and collaborate in an increasing manner. The Applied Optics Group (Dr. Juha Toivonen) develops industrially relevant optical measurement methods. The Nonlinear Optics Group (Prof. Martti Kauranen) studies fundamental issues of nonlinear optics. Of particular interest are multipolar (dipolar, magnetic, and quadrupolar) contributions to the nonlinear response. Another goal is to design nanostructured metamaterials with enhanced nonlinear properties. The Nonlinear Fiber Optics Group (Prof. Goëry Genty) studies nonlinear pulse propagation in waveguides.
