Electronic excitation and atomic forces in optically excited group V semimetals
… Recent experimental work in the group V semimetals have shown that the symmetry-breaking $E_g$ mode is driven by a force which decays in $\sim 10$ fs, a timescale much shorter than the period of the mode, explaining its small amplitude. However, the exact mechanism for this decay has remained …

Scanning tunneling microscopy and spectroscopy study of layered transition metal chalcogenide thin films tuned by thickness, structural phase, and heterostructure
Layered transition metal chalcogenides (TMCs) have a long and fruitful history, exhibiting diverse properties and interesting quantum phenomena, such as superconductivity, charge density wave (CDW), and non-trivial topological states. Since the discovery that layered materials can be exfoliated to …
