Automated regime classification in multidimensional time series data using sliced Wasserstein k-means clustering
Qinmeng Luan, James Hamp
Recent work has proposed Wasserstein k-means (Wk-means) clustering as a powerful method to classify regimes in time series data, and one-dimensional asset returns in particular. In…
Supercooling and fragile glassiness in a dipolar kagome Ising magnet
James Hamp, Roderich Moessner, Claudio Castelnovo
We study equilibration and ordering in the classical dipolar kagome Ising antiferromagnet, which we show behaves as a disorder-free fragile spin glass. By identifying an appropriat…
Emergent Order in the Kagome Ising Magnet Dy3Mg2Sb3O14
Joseph A. M. Paddison, Harapan S. Ong, James O. Hamp +7
The kagome lattice -- a two-dimensional (2D) arrangement of corner-sharing triangles -- is at the forefront of the search for exotic states generated by magnetic frustration. Such…
Emergent Coulombic criticality and Kibble-Zurek scaling in a topological magnet
James Hamp, Anushya Chandran, Roderich Moessner +1
When a classical system is driven through a continuous phase transition, its nonequilibrium response is universal and exhibits Kibble-Zurek scaling. We explore this dynamical scali…
