Effect of disorder on topological charge pumping in the Rice-Mele model
A. L. C. Hayward, E. Bertok, U. Schneider +1
Recent experiments with ultracold quantum gases have successfully realized integer-quantized topological charge pumping in optical lattices. Motivated by this progress, we study th…
Topological phases in the Fermi-Hofstadter-Hubbard model on hybrid-space ladders
Leo Stenzel, Andrew L. C. Hayward, Ulrich Schollwöck +1
In recent experiments with ultracold atoms, both two-dimensional (2d) Chern insulators and one-dimensional (1d) topological charge pumps have been realized. Without interactions, b…
Quantum phases and topological properties of interacting fermions in one-dimensional superlattices
Leo Stenzel, Andrew L. C. Hayward, Claudius Hubig +2
The realization of artificial gauge fields in ultracold atomic gases has opened up a path towards experimental studies of topological insulators and, as an ultimate goal, topologic…
Topological charge pumping in the interacting bosonic Rice-Mele model
A. L. C. Hayward, C. Schweizer, M. Lohse +2
We investigate topological charge pumping in a system of interacting bosons in the tight-binding limit, described by the Rice-Mele model. An appropriate topological invariant for t…
Pfaffian States in Coupled Atom-Cavity Systems
Andrew L. C. Hayward, Andrew M. Martin
Coupled atom-cavity arrays, such as those described by the Jaynes-Cummings Hubbard model, have the potential to emulate a wide range of condensed matter phenomena. In particular, t…
Superfluid-Mott transitions and vortices in the Jaynes-Cummings-Hubbard lattices with time reversal symmetry breaking
Andrew L. C. Hayward, Andrew M. Martin
We investigate the groundstate behaviour of Jaynes-Cummings-Hubbard lattices in the presence of a synthetic magnetic field, via a Gutzwiller ansatz. Specifically, we study the Mott…
Supersolid phases of light in extended Jaynes-Cummings-Hubbard systems
Bogusz Bujnowski, Justine K. Corso, Andrew L. C. Hayward +2
Jaynes-Cummings-Hubbard lattices provide unique properties for the study of correlated phases as they exhibit convenient state preparation and measurement, as well as "in situ" tun…
Interferometry using Adiabatic Passage in Dilute Gas Bose-Einstein Condensates
M. Rab, A. L. C. Hayward, J. H. Cole +2
We theoretically examine three-well interferometry in Bose-Einstein condensates using adiabatic passage. Specifically, we demonstrate that a fractional coherent transport adiabatic…
Fractional Quantum Hall Physics in Jaynes-Cummings-Hubbard Lattices
Andrew L. C. Hayward, Andrew M. Martin, Andrew D. Greentree
Jaynes-Cummings-Hubbard arrays provide unique opportunities for quantum emulation as they exhibit convenient state preparation and measurement, and in-situ tuning of parameters. We…
Quantum and Classical Chaos in Kicked Coupled Jaynes-Cummings Cavities
A. L. C. Hayward, Andrew D. Greentree
We consider two Jaynes-Cummings cavities coupled periodically with a photon hopping term. The semi-classical phase space is chaotic, with regions of stability over some ranges of t…
