Optoelectronic polymer memristors with dynamic control for power-efficient in-sensor edge computing
Multi-functional optoelectronic memristive features
To counter these challenges, we built a compact RC system for future in-sensor platforms using the same type of tunable organic optoelectronic memristors. We introduced the…

Bright squeezed light in the kilohertz frequency band
Principle analysis
The schematic diagram of bright squeezed light generation is shown in Fig. 1a, which depicts a nonclassical active feedback scheme with the assistance of a squeezed vacuum. Prior to the active feedback stage, the free-running…

Scientists Watch an Atom’s Nucleus Flip in Real Time for the First Time
Artist’s impression, based on actual measurement data, of the nuclear spin of an atom flipping between distinct quantum states. The flipping was observed as a fluctuation in the electrical current passing through the atom on a… Continue Reading
