Fractal ground state of ion chains in periodic potentials
Raphaël Menu, Jorge Yago Malo, Vladan VuletiÄ +2
Trapped ions in a periodic potential are a paradigm of a frustrated Wigner crystal. The dynamics is captured by a long-range Frenkel-Kontorova model. The classical ground state can…

Quantum frustrated Wigner chains
Raphaël Menu, Jorge Yago Malo, Vladan VuletiÄ +2
A Wigner chain in a periodic potential is a paradigmatic example of geometric frustration with long-range interactions. The dynamics emulates the Frenkel-Kontorova model with Coulo…
