Manipulating superconductivity in cuprates with selective ultrafast excitation
"Ultrafast techniques allow an unprecedented look at the electronic and bosonic interactions that govern the macroscopic properties of materials. These processes can now be accessed on their fundamental timescale---the attosecond to picosecond range. Most ultrafast measurements involve using high …

Electronic excitation and atomic forces in optically excited group V semimetals
… of this work is to investigate how electronic excitation changes the forces between atoms in materials, causing large amplitude collective atomic motion, referred to as coherent phonon motion. The recent development of ultrafast optical spectroscopy has greatly advanced our understanding of …
