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…
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…
Anomalous fluctuations of Bose-Einstein condensates in optical lattices
Zahra Jalali-Mola, Niklas Käming, Luca Asteria +6
Fluctuations are fundamental in physics and important for understanding and characterizing phase transitions. In this spirit, the phase transition to the Bose-Einstein condensate (…
A phase microscope for quantum gases
Justus C. Brüggenjürgen, Mathis S. Fischer, Christof Weitenberg
Coherence properties are central to quantum systems and are at the heart of phenomena such as superconductivity. Here we study coherence properties of an ultracold Bose gas in a tw…
