High-Power Polarization-Controlled Attosecond-Scale Soft X-ray Pulses
Zhaoheng Guo, Carlo Vicario, Andre Al Haddad +18
We demonstrate a versatile platform for high-power attosecond soft X-ray pulse generation with polarization and photon energy control at the SwissFEL free-electron laser. An isolat…

Emergent Antiphase Stacking in a Transient Charge Density Wave
Jade Stanton, Gal Orenstein, Ryan A. Duncan +14
Photoexcitation can induce novel states in materials that are inaccessible in equilibrium, a recent example being the light-induced charge density wave (CDW) observed in $\text{LaT…

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…
