Realization of the Hofstadter Hamiltonian with ultracold atoms in optical lattices

M Aidelsburger, M Atala, M Lohse, JT Barreiro… - Physical review …, 2013 - APS
We demonstrate the experimental implementation of an optical lattice that allows for the
generation of large homogeneous and tunable artificial magnetic fields with ultracold atoms …

Dynamic optical superlattices with topological bands

SK Baur, MH Schleier-Smith, NR Cooper - Physical Review A, 2014 - APS
We introduce an all-optical approach to producing high-flux synthetic magnetic fields for
neutral atoms or molecules by designing intrinsically time-periodic optical superlattices. A …

Perturbative approach to flat Chern bands in the Hofstadter model

F Harper, SH Simon, R Roy - Physical Review B, 2014 - APS
We present a perturbative approach to the study of the Hofstadter model for when the
amount of flux per plaquette is close to a rational fraction. Within this approximation, certain …

Strongly interacting bosons on a three-leg ladder in the presence of a homogeneous flux

F Kolley, M Piraud, IP McCulloch… - New Journal of …, 2015 - iopscience.iop.org
We perform a density-matrix renormalization-group study of strongly interacting bosons on a
three-leg ladder in the presence of a homogeneous flux. Focusing on one-third filling, we …

Quantum phases for bosons in a magnetic lattice with a harmonic trap

YF Song, SJ Yang - New Journal of Physics, 2020 - iopscience.iop.org
The phase diagram of ultracold bosons in a 2D optical lattice subjected to a uniform
magnetic flux is studied by the inhomogeneous Gutzwiller variational method. With a …

Loading ultracold gases in topological Floquet bands: the fate of current and center-of-mass responses

A Dauphin, DT Tran, M Lewenstein, N Goldman - 2D Materials, 2017 - iopscience.iop.org
Topological band structures can be designed by subjecting lattice systems to time-periodic
modulations, as was proposed for irradiated graphene, and recently demonstrated in two …

Emergence of a Landau level structure in dark optical lattices

S Nascimbene, J Dalibard - arxiv preprint arxiv:2412.15038, 2024 - arxiv.org
An optical flux lattice is a set of light beams that couple different internal states of an atom,
thereby producing topological energy bands. Here we present a configuration in which the …

The Hofstadter model and other fractional chern insulators

F Harper - 2015 - ora.ox.ac.uk
Fractional Chern insulators (FCIs) are strongly correlated, topological phases of matter that
may exist on a lattice in the presence of broken time-reversal symmetry. This thesis explores …
