Few-body bound topological and flat-band states in a Creutz Ladder
Gerard Pelegrí, Stuart Flannigan, Andrew J. Daley
We investigate the properties of few interacting bosons in a Creutz ladder, which has become a standard model for topological systems, and which can be realised in experiments with…
Many-body spin rotation by adiabatic passage in spin-1/2 XXZ chains of ultracold atoms
Ivana Dimitrova, Stuart Flannigan, Yoo Kyung Lee +6
Quantum many-body phases offer unique properties and emergent phenomena, making them an active area of research. A promising approach for their experimental realization in model sy…
Kaleidoscopes of Hofstadter Butterflies and Aharonov-Bohm caging from -root topology in decorated square lattices
A. M. Marques, J. Mögerle, G. Pelegrí +3
Square-root topology describes models whose topological properties can be revealed upon squaring the Hamiltonian, which produces their respective parent topological insulators. Thi…
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…
