Ultrafast spectroscopy directly measures Raman phonon anharmonicity
What the study found The study reports that ultrafast double pump-probe spectroscopy can directly observe frequency shifts of Raman phonons, which are lattice vibrations that can be detected by light, as a function of oscillation amplitude. It also reports that this approach can separate coherent effects from quasi-harmonic sources such as temperature and changes in…
Mechanical noise squeezing transferred between two modes
What the study found The study reports that mechanical noise squeezing was transferred between two mechanical modes using a single microwave cavity mode as the mediator. Why the authors say this matters The authors say that mechanical noise squeezing across multiple modes is important for precision measurements, and they describe the observed squeezing transfer as…
