Condensed matter physics is the study of condensed phases of matter, primarily the solid and liquid states including their structure and mechanical, electrical, thermal, optical and chemical properties. In addition to presenting rich and fascinating questions about the physical world, it is an area of physics with many real-world applications in such areas as microelectronics, nanomaterials, information storage and communication, biomedical science and engineering, renewable energy, and the development and use of new materials. Furthermore, theoretical results and methods in condensed matter physics have played a major role in other areas of physics, such as astrophysics, cosmology and nuclear physics.<br><br>On-site experimental facilities include X-ray diffractometers, infrared spectrometers, ultrahigh vacuum surface analysis equipment, femtosecond lasers, scanning calorimeters, and atomic force microscopes. In addition, research is conducted at national facilities such as Brookhaven National Laboratory and Oak Ridge National Laboratory. Theoretical researchers make extensive use of the Tufts High Performance Computing facility and the Center for Scientific Visualization. Additionally, the group hosts a biweekly seminar series featuring guest speakers from the New England area.
