Propagation of errors and quantitative quantum simulation with quantum advantage
S. Flannigan, N. Pearson, G. H. Low +5
The rapid development in hardware for quantum computing and simulation has led to much interest in problems where these devices can exceed the capabilities of existing classical co…
Hubbard models and state preparation in an optical Lieb lattice
Stuart Flannigan, Luisa Madail, Ricardo G. Dias +1
Inspired by the growing interest in probing many-body phases in novel two-dimensional lattice geometries we investigate the properties of cold atoms as they could be observed in an…
Interplay between coherent and dissipative dynamics of bosonic doublons in an optical lattice
M. J. Mark, S. Flannigan, F. Meinert +4
We observe the dissipative dynamics of a dense, strongly interacting gas of bosonic atom pairs in an optical lattice, controlling the strength of the two-body interactions over a w…
Enhanced repulsively bound atom pairs in topological optical lattice ladders
Stuart Flannigan, Andrew J. Daley
There is a growing interest in using cold-atom systems to explore the effects of strong interactions in topological band structures. Here we investigate interacting bosons in a Cru…
Collisionally inhomogeneous Bose-Einstein condensates with a linear interaction gradient
Andrea Di Carli, Grant Henderson, Stuart Flannigan +6
We study the evolution of a collisionally inhomogeneous matter wave in a spatial gradient of the interaction strength. Starting with a Bose-Einstein condensate with weak repulsive…
Excitation modes of bright matter-wave solitons
Andrea Di Carli, Craig D. Colquhoun, Grant Henderson +5
We experimentally study the excitation modes of bright matter-wave solitons in a quasi-one-dimensional geometry. The solitons are created by quenching the interactions of a Bose-Ei…
