Synthetic dimensions for topological and quantum phases: Perspective
Javier Argüello-Luengo, Utso Bhattacharya, Alessio Celi +8
In this Perspective article we report on recent progress on studies of synthetic dimensions, mostly, but not only, based on the research realized around the Barcelona groups (ICFO,…
Entanglement and squeezing of the optical field modes in high harmonic generation
Philipp Stammer, Javier Rivera-Dean, Andrew S. Maxwell +5
Squeezing of optical fields, used as a powerful resource for many applications, and the radiation properties in the process of high harmonic generation have thus far been considere…
Eigenstate Thermalization and its breakdown in Quantum Spin Chains with Inhomogeneous Interactions
Ding-Zu Wang, Hao Zhu, Jian Cui +5
The eigenstate thermalization hypothesis (ETH) is a successful theory that establishes the criteria for ergodicity and thermalization in isolated quantum many-body systems. In this…
Competing order in two-band Bose-Hubbard chains with extended-range interactions
Yuma Watanabe, Utso Bhattacharya, Ravindra W. Chhajlany +3
Motivated by the recent progress in realizing and controlling extended Bose-Hubbard systems using excitonic or atomic devices, the present Letter theoretically investigates the cas…
Stabilization of Hubbard-Thouless pumps through nonlocal fermionic repulsion
Javier Argüello-Luengo, Manfred J. Mark, Francesca Ferlaino +3
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 mode…
Analog simulation of high harmonic generation in atoms
Javier Argüello-Luengo, Javier Rivera-Dean, Philipp Stammer +4
The demanding experimental access to the ultrafast dynamics of materials challenges our understanding of their electronic response to applied strong laser fields. For this purpose,…
