Quantum criticality in Ising chains with random hyperuniform couplings
Philip J. D. Crowley, C. R. Laumann, Sarang Gopalakrishnan
We study quantum phase transitions in transverse-field Ising spin chains in which the couplings are random but hyperuniform, in the sense that their large-scale fluctuations are su…

Topological classification of quasi-periodically driven quantum systems
Philip J. D. Crowley, Ivar Martin, Anushya Chandran
Few level quantum systems driven by incommensurate fundamental frequencies exhibit temporal analogues of non-interacting phenomena in spatial dimensio…
