Diffraction limited focusing and routing of gap plasmons by a metal-dielectric-metal lens
Brian S. Dennis, David A. Czaplewski, Michael I. Haftel +3
Passive optical elements can play key roles in photonic applications such as plasmonic integrated circuits. Here we experimentally demonstrate passive gap-plasmon focusing and rout…
Ultracompact Nano-Mechanical Plasmonic Phase Modulators
Brian S. Dennis, Michael I. Haftel, David A. Czaplewski +3
Dielectrics' refractive index limits photonics miniaturization. By coupling light to metal's free electrons, plasmonic devices achieve deeper localization, which scales with the de…
Higher Energy Composite Fermion Levels in the Fractional Quantum Hall Effect
Trevor D. Rhone, Dwipesh Majumder, Brian S. Dennis +9
Even though composite fermions in the fractional quantum Hall liquid are well established, it is not yet known up to what energies they remain intact. We probe the high-energy spec…
Observation of non-conventional spin waves in composite fermion ferromagnets
U. Wurstbauer, S. S. Mandal, D. Majumder +8
We find unexpected low energy excitations of fully spin-polarized composite-fermion ferromagnets in the fractional quantum Hall liquid, resulting from a complex interplay between a…
Spin Order and Excitations in Triangular Antiferromagnet La2Ca2MnO7
Wei Bao, Y. X. Wang, Y. Qiu +6
We report a spin S = 3/2 triangular antiferromagnet with nearest-neighbor coupling J = 0.29 meV in La2Ca2MnO7. A genuinely two-dimensional, three-sublattice order develops below 2.…
Observation of Leggett's collective mode in a multi-band MgB2 superconductor
G. Blumberg, A. Mialitsin, B. S. Dennis +3
We report observation of Leggett's collective mode in a multi-band MgB2 superconductor with T_c=39K arising from the fluctuations in the relative phase between two superconducting…
