Abstract
Time- and angle-resolved XUV-photoemission at the border of the first Brillouin zone is employed to monitor the ultrafast suppression of a (2×2×2) reconstruction characteristic for the charge density wave (CDW) phase in 1T-TiSe2. The correlation of lattice dynamics and transient electronic response, which is probed in this experiment in parallel, provides new insights into the puzzling nature of the CDW mechanism in 1T-TiSe2.
