Optical levitation of glass nanosphere enables quantum control

Researchers at ETH Zurich have trapped a tiny sphere measuring a hundred nanometres using laser light and slowed down its motion to the lowest quantum mechanical state. This technique could help researchers to study quantum ...

Novel liquid crystal metalens offers electric zoom

Researchers from Cornell University's School of Applied and Engineering Physics and Samsung's Advanced Institute of Technology have created a first-of-its-kind metalens—a metamaterial lens—that can be focused using voltage ...

Quantum tunneling pushes the limits of self-powered sensors

Shantanu Chakrabartty's laboratory has been working to create sensors that can run on the least amount of energy. His lab has been so successful at building smaller and more efficient sensors, that they've run into a roadblock ...

Collaboration sparks new model for ceramic conductivity

As insulators, metal oxides—also known as ceramics—may not seem like obvious candidates for electrical conductivity. While electrons zip back and forth in regular metals, their movement in ceramic materials is sluggish ...
