Sub-Nanoscale Observation of Magnetic Monopole Noise

Project description

Pioneering instrument to detect magnetic monopole noise

The magnetic monopole, an elementary particle proposed by Dirac in 1931that is the magnetic equivalent of an electric point charge, is an isolated magnet with one magnetic pole rather than two. Although it has now been created in the lab, it has yet to be detected naturally due to the limited spatial resolution of probes and the required temperatures. With the support of the Marie Skłodowska-Curie Actions programme, the SNOMAN project aims to overcome these barriers by developing a so-called scanned spin-noise microscope that will operate in a cryogen-free dilution refrigerator to slow down the monopole dynamics. This pioneering instrument could enable a sub-nanoscale observation of magnetic monopole noise for the first time.

Objective

The magnetic version of the electron, the Dirac magnetic monopole, although predicted to exist, has yet to be discovered. Recently, the search for emergent magnetic monopoles in quantum materials has focused on spin-ice compounds, which host magnetic monopoles as emergent quasiparticles. Even though emergent monopoles have been studied using the toolbox of quantum matter research, the long awaited monopole detection is still lacking because of the limited low spatial resolution probes and temperature range of the experiments. In this proposal, I present a plan to develop a novel concept called Scanned Spin-Noise Microscope (SSNM) and provide a cutting-edge instrument for realising a Sub-Nanoscale Observation of MAgnetic monopole Noise (SNOMAN). The SSNM will be designed to operate in a cryogen-free dilution refrigerator to slow down the monopole dynamics and realise the long-awaited single monopole detection. I aim to undertake this project under the supervision of Prof. Seamus Davis at University College Cork, where all the necessary facilities and expertise are available to achieve the objectives described in this proposal.
