Dirac-Schwinger Quantization for Emergent Magnetic Monopoles?
A. Farhan, M. Saccone, B. F. L. Ward
In Refs.[1-4] Dirac and Schwinger showed the existence of a magnetic monopole required a charge quantization condition which we write following Dirac as $\frac{eg}{4π\hbar}=\frac{n…
Complex field reversal dynamics in nanomagnetic systems
Michael Saccone, Francesco Caravelli
Nanomagnetic materials, built from thin, patterned films of ferromagnetic materials, began as analogues to frustrated magnetism. Their low energy of operation and emergent properti…
Exploring the phases of 3D artificial spin ice: From Coulomb phase to magnetic monopole crystal
M. Saccone, A. Van den Berg, E. Harding +4
Artificial spin-ices consist of lithographic arrays of single-domain magnetic nanowires organised into frustrated lattices. These geometries are usually two-dimensional, allowing a…
From Vertices to Vortices in magnetic nanoislands
Michael Saccone, Jack C. Gartside, Kilian D. Stenning +2
Recent studies in magnetic nanolithography show that a variety of complex magnetic states emerge as a function of a single magnetic island's aspect ratio. We propose a model which,…
Direct observation of a dynamical glass transition in a nanomagnetic artificial Hopfield network
Michael Saccone, Francesco Caravelli, Kevin Hofhuis +7
Spin glasses, generally defined as disordered systems with randomized competing interactions, are a widely investigated complex system. Theoretical models describing spin glasses a…
Macroscopic Magnetic Monopoles in a 3D-Printed Mechano-Magnet
Hamilton A. Teixeira, Maria F. Bernardo, Michael D. Saccone +3
The notion of magnetic monopoles has puzzled physicists since the introduction of Maxwell's Equations and famously Dirac had hypothesized them in the context of quantum mechanics.…
On the Degeneracy of Spin Ice Graphs, and its Estimate via the Bethe Permanent
Francesco Caravelli, Michael Saccone, Cristiano Nisoli
The concept of spin ice can be extended to a general graph. We study the degeneracy of spin ice graph on arbitrary interaction structures via graph theory. Via the mapping of spin…
Magnetic Charge Propagation upon a 3D Artificial Spin-ice
Andrew May, Michael Saccone, Arjen van den Berg +3
Magnetic charge propagation in bulk frustrated materials has yielded a paradigm-shift in science, allowing the symmetry between electricity and magnetism to be studied. Recent work…
