Dark states are quantum states in which a system does not interact with external fields, such as light (i.e., photons) or electromagnetic fields. These states, which generally occur due to ...

A new chip-scale spectrometer challenges the long-standing reliance on bulky optical systems by replacing physical light ...

Physicists achieve major leap in precision and accuracy at extremely low light levels. Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for ...

The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the fact that its simplest form consists of only one proton and one electron, ...

A modern scientific team has replicated Thomas Edison’s light bulb experiment and discovered it can produce graphene, a material unknown in his time. Using Raman spectroscopy, researchers confirmed ...

Fig. 1: Experimental setup for attosecond-pump attosecond-probe spectroscopy. NIR pulses are focused behind a pulsed gas jet, where attosecond pulses are generated. At some distance from the gas jet, ...

Spectroscopy isn’t just for scientists in lab coats—it’s a toolkit anyone can learn to use for uncovering the hidden architecture of molecules. By combining NMR, IR, and other techniques, chemists can ...

“Juggling. This has taught me an important skill which also serves as a metaphor for my life—work as hard as you can to catch the fastest falling ball before you drop it. I’ve had mixed success so far ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...
