Tunable Single-Ion Anisotropy in Spin-1 Models Realized with Ultracold Atoms
Woo Chang Chung, Julius de Hond, Jinggang Xiang +2
Mott insulator plateaus in optical lattices are a versatile platform to study spin physics. Using sites occupied by two bosons with an internal degree of freedom, we realize a unia…

Interplay between van der Waals and dipole-dipole interactions among Rydberg atoms
Julius de Hond, Nataly Cisternas, R. J. C. Spreeuw +2
Coherently manipulating Rydberg atoms in mesoscopic systems has proven challenging due to the unwanted population of nearby Rydberg levels by black-body radiation. Recently, there…

From coherent collective excitation to Rydberg blockade on an atom chip
Julius de Hond, Rick van Bijnen, S. J. J. M. F. Kokkelmans +3
Using time-resolved measurements, we demonstrate coherent collective Rydberg excitation crossing over into Rydberg blockade in a dense and ultracold gas trapped at a distance of 10…
