Adiabatic realization of anomalous Floquet topological systems
Luca Asteria, Marcel N. Kosch, Henrik P. Zahn +4
Topology has emerged as a central concept for classifying phases of matter. The situation is especially rich in periodically driven systems, where anomalous Floquet topological pha…
Adiabatic preparation of a fractional quantum Hall fluid by coherently pumping atoms from a Bose-Einstein condensate
Alberto Tabarelli de Fatis, Christof Weitenberg, Alexander Schnell +2
We propose a protocol to adiabatically prepare a many-particle fractional quantum Hall fluid of bosonic ultracold atoms exploiting a time-dependent coherent coupling of a strongly…
Micromotion area as proxy for anomalous Floquet topological systems
Luca Asteria, Klaus Sengstock, André Eckardt +1
Driven Floquet systems can realize topological phases with no static counterparts. These so-called anomalous Floquet topology breaks the bulk-boundary correspondence based on the C…
Phase-space microscopes for quantum gases: Imaging conjugate variables and momentum-weighted densities
N. R. Cooper, Y. Yang, C. Weitenberg
Quantum gas microscopes offer unprecedented insights into quantum many-body states of cold atomic gases. Here we introduce concrete protocols for extending quantum gas microscopes…
Protocols for a many-body phase microscope: From coherences and d-wave superconductivity to Green's functions
Christof Weitenberg, Luca Asteria, Ola Carlsson +2
Quantum gas microscopes probe quantum many-body lattice states via projective measurements in the occupation basis, enabling access to various density and spin correlations. Phase…
Mechanisms of localization in a finite harmonically confined optical superlattice
A. Katsaris, I. A. Englezos, C. Weitenberg +2
We investigate the impact of harmonic confinement in a finite optical superlattice and reveal the different mechanisms that can lead to the emergence of localized states. The optic…
