Marina Epelman will be joining the council of the Mathematical Optimization Society (MOS) for three years in the role of treasurer. MOS is an international organization that publishes the Mathematical Programming journal series and sponsors the tri-annual International Symposium on Mathematical Programming, among other activities. Prof. Epelman was elected to the position last year, and will join the council on August 1, 2016.

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
