Prof. Johanna Mathieu is working on one of four projects in computational science that earned a Michigan Institute for Computational Discovery and Engineering Catalyst Grant, an award of $75,000. The proposals were judged on novelty, likelihood of success, potential for external funding, and potential to leverage Advanced Research Computing’s existing computing resources.

Mathieu is participating in a project titled “Computational Energy Systems,” which will develop new algorithms for the U.S. electrical power grid that integrate renewable energy sources, electrification of transportation systems, the increasing frequency of extreme weather events, and other emerging contingencies.

The project is a joint effort by Mathieu and four Industrial and Operations Engineering faculty, Profs. Pascal Van Hentenryck, Eunshin Byon, Ruiwei Jiang, and Jon Lee.

Mathieu works on solving similar problems in her other research, with a focus on integrating wind and solar energy into existing power grid infrastructures and on reducing the environmental impact, cost, and inefficiency of electric power systems via new operational and control strategies.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
