Disentangling Electronic, Lattice and Spin Dynamics in the Chiral Helimagnet Cr1/3NbS2
N. Sirica, H. Hedayat, D. Bugini +7
We investigate the static and ultrafast magneto-optical response of the hexagonal chiral helimagnet above and below the helimagnetic ordering temperature. The pre…
Ultrafast Evolution of Bulk, Surface and Surface Resonance States in Photoexcited BiTe
Hamoon Hedayat, Davide Bugini, Hemian Yi +5
We use circular dichroism (CD) in time- and angle-resolved photoemission spectroscopy (trARPES) to measure the femtosecond charge dynamics in the topological insulator (TI) Bi$_{2}…
Excitonic and lattice contributions to the charge density wave in 1T-TiSe revealed by a phonon bottleneck
Hamoon Hedayat, Charles J. Sayers, Davide Bugini +10
Understanding collective electronic states such as superconductivity and charge density waves is pivotal for fundamental science and applications. The layered transition metal dich…
Role of matrix elements in the time-resolved photoemission signal
F. Boschini, D. Bugini, M. Zonno +17
Time- and angle-resolved photoemission spectroscopy accesses the ultrafast evolution of quasiparticles and many-body interactions in solid-state systems. However, the momentum- and…
