Exchange-striction driven ultrafast nonthermal lattice dynamics in NiO
Y. W. Windsor, D. Zahn, R. Kamrla +7
We use femtosecond electron diffraction to study ultrafast lattice dynamics in the highly correlated antiferromagnetic (AF) semiconductor NiO. Using the scattering vector (Q) depen…
Ultrafast Dynamical Lifshitz Transition
Samuel Beaulieu, Shuo Dong, Nicolas Tancogne-Dejean +9
Fermi surface is at the heart of our understanding of metals and strongly correlated many-body systems. An abrupt change in the Fermi surface topology, also called Lifshitz transit…
Excited state band mapping and momentum-resolved ultrafast population dynamics in In/Si(111) nanowires investigated with XUV based time- and angle-resolved photoemission spectroscopy
C. W. Nicholson, M. Puppin, A. Lücke +6
We investigate the excited state electronic structure of the model phase transition system In/Si(111) using femtosecond time- and angle-resolved photoemission spectroscopy (trARPES…
Beyond the molecular movie: dynamics of bands and bonds during a photo-induced phase transition
Christopher W. Nicholson, Andreas Lücke, Wolf Gero Schmidt +4
Ultrafast non-equilibrium dynamics offer a route to study the microscopic interactions that govern macroscopic behavior. In particular, photo-induced phase transitions (PIPTs) in s…
Revealing the role of electrons and phonons in the ultrafast recovery of charge density wave correlations in 1-TiSe
C. Monney, M. Puppin, C. W. Nicholson +8
Using time- and angle-resolved photoemission spectroscopy with selective near- and mid-infrared photon excitations, we investigate the femtosecond dynamics of the charge density wa…
