Emmy Noether Junior Research Group "Quantum Critical Matter"

We investigate a variety of strongly-correlated systems from the common viewpoint of quantum criticality. This includes models for frustrated magnets and interacting semimetals, as well as quantum critical systems that are described by emergent gauge field theories. What are the characteristic excitations? What are the relevant interactions? What is the nature of the QCP and its adjacent phases? How can a material be tuned through a QCP into a regime that stabilizes a novel quantum phase?

Methodologically and conceptually we benefit from recent synergistic developments in condensed matter, high-energy, and statistical physics, as well as quantum information theory, and we intend to also further advance these emergent bridges between different fields.

Our group is part of the Cluster of Excellence ct.qmat and the Collaborative Research Center SFB1143.
