Helical boundary modes from synthetic spin in a plasmonic lattice
Sang Hyun Park, Michael Sammon, Eugene Mele +1
Artificial lattices have been used as a platform to extend the application of topological physics beyond electronic systems. Here, using the two-dimensional Lieb lattice as a proto…
Broadband Focusing of Acoustic Plasmons in Graphene with an Applied Current
Michael Sammon, Dionisios Margetis, E. J. Mele +1
Non-reciprocal plasmons in current-driven, isotropic, and homogenous graphene with proximal metallic gates is theoretically explored. Nearby metallic gates screen the Coulomb inter…
Isotropically conducting (hidden) quantum Hall stripe phases in a two-dimensional electron gas
Yi Huang, M. Sammon, M. A. Zudov +1
Quantum Hall stripe (QHS) phases, predicted by the Hartree-Fock theory, are manifested in GaAs-based two-dimensional electron gases as giant resistance anisotropies. Here, we predi…
Resistivity anisotropy of quantum Hall stripe phases
Michael Sammon, Xiaojun Fu, Yi Huang +8
Quantum Hall stripe phases near half-integer filling factors were predicted by Hartree-Fock (HF) theory and confirmed by discoveries of giant resistance anisotropies in…
Giant violation of Wiedemann-Franz law in doping layers of modern AlGaAs heterostructures
M. Sammon, Mitali Banerjee, B. I. Shklovskii
We analyze the data of the recent paper Nature 559, 205 (2018) and show that it contains an observation of thermal and electric conductivities of the doping layers in GaAs/AlGaAs h…
Attraction of indirect excitons in van der Waals heterostructures with three semiconducting layers
M. Sammon, B. I. Shklovskii
We study a capacitor made of three monolayers of transition metal dichalcogenide (TMD) separated by hexagonal Boron Nitride (hBN). We assume that the structure is symmetric with re…
