A new twist on an old tool lets scientists use light to study and control matter with 1,000 times better resolution and precision than previously possible. Physicists have demonstrated "ponderomotive ...

Raman spectroscopy is used to characterize materials by analyzing molecular or crystal rotations and vibrations that are excited by a laser, and exhibit vibrations that are specific to the molecules ...

In a recent article published in Nature Nanotechnology, researchers introduced an approach in single-molecule spectroscopy, significantly improving the ability to probe quantum transitions in ...

Spectroscopy is an essential tool in understanding and manipulating quantum systems, such as atoms and molecules. The model describing spectroscopy includes the multipole-field interaction, which ...

Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) have developed a novel method for investigating the internal structure of atoms and discovered ...

Researchers from the Institute of Solid State Physics, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with Southwest Jiaotong University, have combined ...

An ultraviolet photon-counting dual-comb spectrometer. Two ultraviolet frequency combs of slightly different pulse repetition frequencies are generated at very low light levels by nonlinear frequency ...
