Seeing stable topology using instabilities

We are most familiar with the four conventional phases of matter: solid, liquid, gas, and plasma. Changes between two phases, known as phase transitions, are marked by abrupt changes in material properties such as density. ...

Intelligent nanomaterials for photonics

Since the Nobel Prize in Physics was awarded for research on graphene in 2010, 2-D materials—nanosheets with atomic thickness—have been a hot topic in science. This significant interest is due to their outstanding properties, ...

Shedding new light on nanolasers using 2-D semiconductors

In his latest line of research, Cun-Zheng Ning, a professor of electrical engineering in the Ira A. Fulton Schools of Engineering at Arizona State University, and his peers explored the intricate balance of physics that governs ...

1 + 1 does not equal 2 for graphene-like 2-D materials

Physicists from the University of Sheffield have discovered that when two atomically thin graphene-like materials are placed on top of each other their properties change, and a material with novel hybrid properties emerges, ...
