Quasicrystalline Analogue of the Haldane Model
Benedict Burgess, Nigel Cooper
We present a model for a topological quasicrystalline system which is suitable for realisation in cold-atom experiments. We define the model in terms of complex momentum-space coup…
Characterizing topology at nonzero temperature: Topological invariants and indicators in the extended SSH model
Julia D. Hannukainen, Nigel R. Cooper
We compare three complementary diagnostics for mixed Gaussian states at nonzero temperature, focusing on the Su-Schrieffer-Heeger (SSH) chain and its inversion-symmetric extension.…
Ideal Optical Flux Lattices
Ophelia Evelyn Sommer, Nigel R. Cooper
The realization of fractional quantum Hall (FQH) states in cold atomic gases is a long-standing goal in quantum simulation. Established approaches, including rapidly rotating gases…
Gapless Edge Gravitons and Quasiparticles in Fractional Quantum Hall Systems with Non-Local Confinement
Daniel Spasic-Mlacak, Nigel R. Cooper
One of the central tenets of the theory of the fractional quantum Hall effect is that the bulk quantized Hall response requires the existence of a gapless chiral edge mode. The fie…
Additive Manufacturing for Advanced Quantum Technologies
F. Wang, N. Cooper, D. Johnson +7
The development of quantum technology has opened up exciting opportunities to revolutionize computing and communication, timing and navigation systems, enable non-invasive imaging…
