High-harmonic generation during ultrafast melting of a Mott insulating state
Nature · By Ryohei Ikeda ·
The Brief
- A Nature Photonics paper reports high-harmonic generation measurements during the ultrafast melting of a Mott insulating state.
- High-harmonic spectroscopy under an intense mid-infrared field shows redshifts of high-harmonic peaks during the melting process.
- The source states that dynamical mean-field theory is also part of the study, though its details are not given in the excerpt.
Why it matters
The work uses high-harmonic spectroscopy to track a phase transition in a correlated electron material on ultrafast timescales, offering a probe of how Mott insulators lose their insulating state.
