Quantitative infrared nanoscopy: Probe-cavity eigenmodes and nano-gap polaritons for strongly coupled nanoscale optics
Benjamin Allen, Brayden Lukaskawcez, Alyssa Bragg +7
Optical nanoscopies including near-field optical microscopy and spectroscopy circumvent the diffraction limit of conventional optics thanks to the nanoscale light focus emerging at…
Excitonic pattern formation from a wrinkling instability in a van der Waals heterostructure
Zhiwen Zhou, L. H. Fowler-Gerace, W. J. Brunner +4
We studied photoluminescence of spatially indirect excitons (IXs) in a MoSe/WSe van der Waals heterostructure. We observed a quasi-periodic triangular pattern of IXs with a…
Quantum Light Nano-Imaging
Michael Dapolito, Matthew Fu, Fuyang Tay +20
Entanglement and quantum correlations are central to the physics of quantum materials, yet they have remained notoriously difficult to access experimentally. Accessing these phenom…
Diffusive and hydrodynamic magnetotransport around a density perturbation in a two-dimensional electron gas
P. S. Parashar, M. M. Fogler
We study current flow around a density inhomogeneity in a two-dimensional electron gas in the presence of a strong magnetic field. The inhomogeneity is parametrized by a power-law…
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…
