Understanding the Plasmonics of Nanostructured Atomic Force Microscopy Tips
Alan Sanders, Richard W. Bowman, Liwu Zhang +5
Structured metallic tips are increasingly important for optical spectroscopies such as tip-enhanced Raman spectroscopy (TERS), with plasmonic resonances frequently cited as a mecha…
Anomalous spectral shift of near- and far-field plasmonic resonances in nano-gaps
Anna Lombardi, Angela Demetriadou, Lee Weller +5
The near-field and far-field spectral response of plasmonic systems are often assumed to be identical, due to the lack of methods that can directly compare and correlate both respo…
The hyperfine Paschen-Back Faraday effect
Mark A Zentile, Rebecca Andrews, Lee Weller +3
We investigate experimentally and theoretically the Faraday effect in an atomic medium in the hyperfine Paschen-Back regime, where the Zeeman interaction is larger than the hyperfi…
Cooperative Enhancement of Energy Transfer in a High-Density Thermal Vapor
L. Weller, R. J. Bettles, C. L. Vaillant +4
We present an experimental study of energy transfer in a thermal vapor of atomic rubidium. We measure the fluorescence spectrum in the visible and near infra-red as a function of a…
Absolute absorption and dispersion of a rubidium vapour in the hyperfine Paschen-Back regime
Lee Weller, Kathrin S. Kleinbach, Mark A. Zentile +3
Here we report on measurements of the absolute absorption and dispersion properties of an isotopically pure 87Rb vapour for magnetic fields up to and including 0.6 T. We discuss th…
Measuring the Stokes parameters for light transmitted by a high-density rubidium vapour in large magnetic fields
Lee Weller, Toryn Dalton, Paul Siddons +2
Here we report on measurements of the absolute absorption and dispersion of light in a dense rubidium vapour on the D2 line in the weak-probe regime with an applied magnetic field.…
Absolute absorption on rubidium D1 line: including resonant dipole-dipole interactions
Lee Weller, Robert J Bettles, Paul Siddons +2
Here we report on measurements of the absolute absorption spectra of dense rubidium vapour on the D1 line in the weak-probe regime for temperatures up to 170 C and number densities…
