Institute for Theoretical Physics

Theoretical physics uses concepts and methods encoded in mathematical language to explain physical reality. At the Institute for Theoretical Physics, we study physical systems on every scale, ranging from the very small - quantum correction to gravity - to the largest possible scale - the universe.  In between these extremes lie quantum and soft-condensed matter, which study the emergent properties of many-body systems. In theoretical physics, we aim to find answers to some of the most fundamental questions about our world and our existence.
