摘要

Motivated by recent experimental progress towards the detection and manipulation of Majorana fermions in hybrid semiconductor/superconductor heterostructures, we present a novel proposal based on a suspended carbon nanotube resonator with a single-electron spin to probe Majorana fermions in the alloptical domain. With this scheme, a possible Majorana signature is investigated via the probe-absorption spectrum, and the coupling strength between a Majorana fermion and the single-electron spin is also determined. We further show that the carbon nanotube resonator behaves as a phonon cavity and is robust for detecting of Majorana fermions. In the proposal, the single-electron spin can be considered as a sensitive probe. The proposed optical method here may provide a potential supplement for the detection of Majorana fermions.
