Fractal ground state of ion chains in periodic potentials
Raphaël Menu, Jorge Yago Malo, Vladan Vuletić +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…

Counter-factual carving exponentially improves entangled-state fidelity
Joshua Ramette, Josiah Sinclair, Vladan Vuletić
We propose a new method, "counter-factual" carving, that uses the "no-jump" evolution of a probe to generate entangled many-body states of high fidelity. The probe is coupled to a…

Bose-Einstein condensation by polarization gradient laser cooling
Wenchao Xu, Tamara Šumarac, Emily H. Qiu +7
Attempts to create quantum degenerate gases without evaporative cooling have been pursued since the early days of laser cooling, with the consensus that polarization gradient cooli…
