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…

Can multipartite entanglement be characterized by two-point connected correlation functions ?
Luca Lepori, Andrea Trombettoni, Domenico Giuliano +5
We discuss under which conditions multipartite entanglement in mixed quantum states can be characterized only in terms of two-point connected correlation functions, as it is the ca…
