Ultrafast dynamics of excitons in black phosphorus
Geoffroy Kremer, Juan F. P. Mosquera, Joël Morf +9
Excitons are key quasiparticles determining the optical properties of solids. As such, they can be utilized to coherently control the electronic structure of materials using optica…

Ultrafast recovery dynamics of dimer stripes in IrTe2
M. Rumo, G. Kremer, M. Heber +10
The transition metal dichalcogenide IrTe2 displays a remarkable series of first-order phase transitions below room temperature, involving lattice displacements as large as 20 perce…

Bonding states underpinning structural transitions in IrTe observed with micro-ARPES
C. W. Nicholson, M. D. Watson, A. Pulkkinen +6
Competing interactions in low-dimensional materials can produce nearly degenerate electronic and structural phases. We investigate the staircase of structural phase transitions in…
