TL;DR

This paper explores how surface plasmons on a gold nanotip induce photoluminescence in an accelerated frame, suggesting a significant enhancement of nonlinear optical effects due to the Unruh effect.

Contribution

It introduces a novel theoretical framework linking surface plasmon-induced photoluminescence with the Unruh effect in an accelerated reference frame.

Findings

Enhanced nonlinear optical mixing predicted

Potential for observing Unruh-related phenomena

Surface plasmon effects amplified in accelerated frames

Abstract

Photoluminescence from a gold nanotip, which is induced by surface plasmons propagating over a curved tapered nanotip surface is considered in a co-moving accelerated reference frame. Similar to the surface-enhanced Raman scattering (SERS) effect, nonlinear optical mixing of the surface plasmons with the Unruh quanta is supposed to be enhanced by many orders of magnitude.
