APS ViewPoint ‘‘An Accordion Lattice Playing a Soliton Tune’’
Your article on lattice solitons has been featured with a Viewpoint article by the American Physical Society.
We present an experimental setup which provides a versatile environment to study soliton formation and evolution in lattice potentials. Opt. Express 34, 623-637 (2026).
We demonstrated the existence of single- and multi-site solitons in an optical accordion lattice, Phys. Rev. Lett. 135, 263404 (2025).

Interactions in Floquet-driven quantum gases cause unwanted heating and excitation modes. We found a general set of resonance conditions that explain this ‘‘Floquet heating’’ for superfluids in optical lattices. Phys. Rev. Research 6, 023323 (2024).
