An illustration of the egg crate electronic structure, shown between two mirrors so that the red laser light resonates. The polaritons, trapped in the pockets, are represented by the sum of their parts: a green exciton, with electron and hole shown inside, attached to a red lightwave. Even with just a few excitons in the wells, the energy required to add a new one begins to jump

Hacking reality

Microphones that “hear” light; microprocessors that “tell” us secrets; self-driving cars that “see” fake objects; sensors that “feel” the wrong temperature. Our devices are under attack in new, increasingly sophisticated ways. Security researchers at CSE are exploring the limits of hardware and finding new, sobering vulnerabilities in our computers and homes. |Long Read

Pioneering a way to keep very small satellites in orbit

More than 250 students had a hand in a satellite scheduled to launch on January 17th, the first in space for a project to keep nanosats in orbit by harnessing Earth’s magnetic field. |Medium Read
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.
