Topol0gical Matter, Floquet Systems (Time Crystals), Quantum Sensors and Quantum Information
Prof. D.L. Carroll
The Carroll Research Group explores the fundamental roles that dimension, band topology, quantum geometries, and symmetry breaking play in the emergent properties of condensed matter systems. Specifically, we test the limits of interplay between topological k-spaces and the quantum geometry of quantum materials systems. This can lead us to 2D chalcogenides, 1D conjugated organics (SSH topology) and a variety of nano carbons such as graphene. The context of these studies lies in quantum information theory (quantum qubits, quantum registers and quantum computing), in quantum thermodynamics (quantum batteries), and in quantum light sources, sensors, and power systems.
Current Research Opportunities
Quantum Materials: From 2D chalcogenides, graphene, MXenes, and other exotica, to Floquet systems, Anomalous Spin Hall systems, Kagome lattices and Altermagnets, the Topological State Stabilization Conjecture, quantum geometries and band topology.
Quantum Information Processing: Qubits, Quantum registers, QPUs and the theory of quantum information.
Onsager Entanglement: Hybrid piezo-thermoelectric and photovoltaic-thermal systems, quantum power systems, quantum thermodynamics
Organic Device Technologies: AC Organic Light Emitting Devices (FIPELS and FIPEL-lasers) and Organic Photovoltaics, beyond SSH.
Ionic Conductors: Seebeck effects, advanced ion battery concepts and desalination/ionic selection technologies.

Meetings and Gatherings
Group Meetings are held in the Coffee Rm (Squirrels Nest) at N/QTL
Fridays at 9:00 am. Our group meetings are generally open to anyone in the WFU research community and required for all group members.
Conferences the group attends include both the Spring and Fall MRS Meetings, the APS March Meeting, and IWEPNM: International Winterschool on Electronic Properties of Novel Materials. Dr. Carroll also usually speaks at the Nanoworkshop in Schoneck DE.
Physics Department Colloquium is on Thursday 3:30 to 5:00 pm each week.
