Energy flows among coupled subsystems are essential for ultrafast dynamics and high-speed technologies. In magnetic materials, spin fluctuations -- magnons -- mediate these flows i…
Ultrafast Decoherence of Charge Density Waves in KMoO
Rafael T. Winkler, Larissa Boie, Yunpei Deng +20
Recent works have suggested that transient suppression of a charge density wave (CDW) by an ultra-short excitation can lead to an inversion of the CDW phase. We experimentally inve…
