"For thesis topic, “Coherent light-matter interactions in monolayer transition metal dichalcogenides.”"


Edbert Sie received his Ph.D. in physics at MIT in 2017, supervised by Prof. Nuh Gedik. His dissertation made several key contributions to our understanding of light-matter interactions in atomically-thin transition-metal dichalcogenides. By applying ultrafast laser spectroscopy, he has developed a new, dissipationless optical method to control the exciton energy in a valley-selective manner through the optical Stark effect and the Bloch-Siegert shift. He also presented a number of key results on the many-body interactions between excitons in this system. This includes the observation of intervalley biexcitons, biexcitonic optical Stark effect, and the exciton-exciton interactions that mimic the Lennard-Jones interactions between atoms. His dissertation revealed an important connection between light-matter interactions in atoms and solids and should make ways for enhanced optical control in two-dimensional materials. He has received the Springer Nature Thesis Award (2017) for his dissertation work and the Stanford GLAM Fellowship (2017). After receiving his Ph.D., he has been working as a Postdoctoral GLAM Fellow at Stanford University in Prof. Aaron Lindenberg's group, where he uses ultrafast electron diffraction to take snapshots of the atomic-scale structures in motion.
