Anomalous Thermodynamic Properties of Electron Accumulation Layer in SrTiO
Michael Sammon, Han Fu, B. I. Shklovskii
Due to the nonlinear dielectric response within SrTiO (STO), an accumulation layer created by positive charges at the surface of the STO sample () has an electron densit…
Plasmonic gain in current biased tilted Dirac nodes
Sang Hyun Park, Michael Sammon, Eugene Mele +1
Surface plasmons, which allow extreme confinement of light, suffer from high intrinsic electronic losses. It has been shown that stimulated emission of electrons can transfer energ…
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…
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…
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…
