Quantum Materials

IQM mission: To realize, understand, and control revolutionary quantum materials and structures where quantum effects such as entanglement and coherence find collective macroscopic manifestations.

RESEARCH PLAN: Quantum mechanics successfully describes electrons within atoms as matter waves. IQM will develop “Quantum Materials” where electronic matter waves extend beyond the atomic scale and give rise to unique physical properties. IQM theorists will identify candidate materials and nanoscale structures that will be synthesized and then probed with advanced spectroscopic and transport methods to realize and understand four new quantum states of matter and explore their potential for applications.


IQM Organization


Organization Chart
Fig. 1. Organization chart for the IQM EFRC. Color coding indicates the principal methodologies of the individuals: Green for synthesis, blue for experiments, and red for theory. Most PIs are involved in several thrusts areas and some have expertise needed in all of them. This helps to connect the thrusts and build cohesion across the institute. The PIs listed in the lower boxes are projected to spend 20% or more of their EFRC efforts in that area and they will take part in strategic planning for that scientific area. See Fig. 2 for the full thrust participation matrix.
