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…
Exploring 4D Quantum Hall Physics with a 2D Topological Charge Pump
Michael Lohse, Christian Schweizer, Hannah M. Price +2
The discovery of topological states of matter has profoundly augmented our understanding of phase transitions in physical systems. Instead of local order parameters, topological ph…
Spin pumping and measurement of spin currents in optical superlattices
Christian Schweizer, Michael Lohse, Roberta Citro +1
We report on the experimental implementation of a spin pump with ultracold bosonic atoms in an optical superlattice. In the limit of isolated double wells it represents a 1D dynami…
A Thouless Quantum Pump with Ultracold Bosonic Atoms in an Optical Superlattice
Michael Lohse, Christian Schweizer, Oded Zilberberg +2
More than 30 years ago, Thouless introduced the concept of a topological charge pump that would enable the robust transport of charge through an adiabatic cyclic evolution of the u…
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…
