Research at FTPI includes the major areas of theoretical physics:  
High Energy Particle Physics, Astrophysics and Cosmology, 
and Condensed Matter


In addition to supporting the faculty, postdoctoral researchers, and graduate students involved in this research at the Institute, FTPI also hosts short-term and long-term visitors and organizes workshops on topics of acute interest in the major areas of study.

High Energy Particle

The High Energy Theory Group focuses on understanding the fundamental forces of nature and cosmology. The unification of the electromagnetic and weak nuclear force is well understood and is continually being tested experimentally. Among the objectives of the group in Minnesota is to push our understanding beyond the Standard Model of electroweak interactions. The strong nuclear force is inherently more complicated and understanding the nature of strongly interacting systems  is another major objective of the group.

Condensed Matter

The Condensed Matter Theory Group strives to understand how the microscopic behavior of a very large number of atoms or molecules is related to the macroscopic properties of solids and liquids. While this certainly applies to objects common in our daily lives, such as kitchen salt or water, we are also interested in quantum versions of solids, liquids, and gases.
