Synthetic dimensions for topological and quantum phases
Javier Argüello-Luengo, Utso Bhattacharya, Alessio Celi, Ravindra W. Chhajlany, Tobias Grass, Marcin Płodzień, Debraj Rakshit, Tymoteusz Salamon, Paolo Stornati, Leticia Tarruell, and Maciej Lewenstein
Commun Phys 7, 143 () | arXiv:2310.19549 [quant-ph]The concept of synthetic dimensions works particularly well in atomic physics, quantum optics, and photonics, where the internal degrees of freedom (Zeeman sublevels of the ground state, metastable excited states, or motional states for atoms, and …

Phys. Rev. Research 6, 023050 () | arXiv:2306.06173 [quant-ph]Dynamical generation of strong and scalable quantum resources, like many-body entanglement and Bell correlations, in spin-1/2 chains is possible with all-to-all interactions, either for constant interaction strength realizing one-axis twisting …

Stabilization of Hubbard-Thouless pumps through nonlocal fermionic repulsion
Javier Argüello-Luengo, Manfred J. Mark, Francesca Ferlaino, Maciej Lewenstein, Luca Barbiero, and Sergi Julià-Farré
Quantum 8, 1285 () | arXiv:2308.13375 [cond-mat.quant-gas]Thouless pumping represents a powerful concept to probe quantized topological invariants in quantum systems. We explore this mechanism in a generalized Rice-Mele Fermi-Hubbard model characterized by the presence of competing onsite and intersite …
