Wavevector analysis of plasmon-assisted distributed nonlinear photoluminescence along Au nanowire antennas
Deepak K. Sharma, Adrian Agreda, Julien Barthes +3
We report a quantitative analysis of the wavevector diagram emitted by nonlinear photoluminescence generated by a tightly focused pulsed laser beam and distributed along Au nanowir…
Plasmonic Purcell factor and coupling efficiency to surface plasmons. Implications for addressing and controlling optical nanosources
G. Colas des Francs, J. Barthes, A. Bouhelier +2
The Purcell factor is a key quantity in cavity quantum electrodynamics (cQED) that quantifies the coupling rate between a dipolar emitter and a cavity mode. Its simple form $…
Purcell factor for point-like dipolar emitter coupling to 2D-plasmonic waveguides
J. Barthes, G. Colas des Francs, A. Bouhelier +2
We theoretically investigate the spontaneous emission of a point--like dipolar emitter located near a two--dimensional (2D) plasmonic waveguide of arbitrary form. We invoke an expl…
On the Sunyaev-Zel'dovich effect from dark matter annihilation or decay in galaxy clusters
Julien Lavalle, Celine Boehm, Julien Barthes
We revisit the prospects for detecting the Sunyaev Zel'dovich (SZ) effect induced by dark matter (DM) annihilation or decay. We show that with standard (or even extreme) assumption…
