Floquet topological transitions in a driven one-dimensional topological insulator
V. Dal Lago, M. Atala, L. E. F. Foa Torres
The Su-Schrieffer-Heeger model of polyacetylene is a paradigmatic Hamiltonian exhibiting non-trivial edge states. By using Floquet theory we study how the spectrum of this one-dime…
Measuring the Chern number of Hofstadter bands with ultracold bosonic atoms
M. Aidelsburger, M. Lohse, C. Schweizer +6
Sixty years ago, Karplus and Luttinger pointed out that quantum particles moving on a lattice could acquire an anomalous transverse velocity in response to a force, providing an ex…
Observation of the Meissner effect with ultracold atoms in bosonic ladders
M. Atala, M. Aidelsburger, M. Lohse +3
We report on the observation of the Meissner effect in bosonic flux ladders of ultracold atoms. Using artificial gauge fields induced by laser-assisted tunneling, we realize arrays…
Realization of the Hofstadter Hamiltonian with ultracold atoms in optical lattices
M. Aidelsburger, M. Atala, M. Lohse +3
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…
Direct Measurement of the Zak phase in Topological Bloch Bands
Marcos Atala, Monika Aidelsburger, Julio T. Barreiro +4
Geometric phases that characterize the topological properties of Bloch bands play a fundamental role in the modern band theory of solids. Here we report on the direct measurement o…
Experimental realization of strong effective magnetic fields in optical superlattice potentials
Monika Aidelsburger, Marcos Atala, Sylvain Nascimbène +3
We present the experimental generation of large effective magnetic fields for ultracold atoms using photon-assisted tunneling in an optical superlattice. The underlying method does…
