Quantum materials QED with van der Waals crystals
Suheng Xu, Brian Vermilyea, Ran Jing +19
A central goal of the emerging field of materials QED is to harness subwavelength electromagnetic confinement in engineered cavities to tailor light-matter interactions. Here, we d…
Plasmon dynamics in graphene
Suheng Xu, Birui Yang, Nishchhal Verma +15
Plasmon are collective oscillations of mobile electrons with dynamics controlled by their charge stiffness("Drude weight"). Using terahertz spacetime metrology, we probe Plasmon dy…
Twisted bilayer graphene as a terahertz plasmonic crystal
Brian S. Vermilyea, Michael M. Fogler
We study surface plasmons in minimally-twisted gapped bilayer graphene that contains a triangular network of partial dislocations (or AB-BA domain walls) hosting topologically prot…
Mott transition in excitonic Bose polarons
E. A. Szwed, B. Vermilyea, D. J. Choksy +5
For a neutral system of positive and negative charges, such as atoms in a crystal, increasing the density causes the Mott transition from bound electrons to free electrons. The den…
Excitonic Bose-polarons in electron-hole bilayers
E. A. Szwed, B. Vermilyea, D. J. Choksy +6
Bose polarons are mobile impurities dressed by density fluctuations of a surrounding degenerate Bose gas. These many-body objects have been realized in ultracold atomic gasses and…
Nano-Imaging of Landau-Phonon Polaritons in Dirac Heterostructures
Lukas Wehmeier, Suheng Xu, Rafael A. Mayer +19
Polaritons are light-matter quasiparticles that govern the optical response of quantum materials and enable their nanophotonic applications. We have studied a new type of polariton…
Feshbach resonance of heavy exciton-polaritons
Brian Vermilyea, Michael M. Fogler
We study interactions between polaritons formed by hybridization of excitons in a two-dimensional (2D) semiconductor with surface optical phonons or plasmons. These quasiparticles…
