Coherent light scattering from a two-dimensional Mott insulator
Christof Weitenberg, Peter Schauß, Takeshi Fukuhara +4
We experimentally demonstrate coherent light scattering from an atomic Mott insulator in a two-dimensional lattice. The far-field diffraction pattern of small clouds of a few hundr…
Single-Spin Addressing in an Atomic Mott Insulator
Christof Weitenberg, Manuel Endres, Jacob F. Sherson +5
Ultracold atoms in optical lattices are a versatile tool to investigate fundamental properties of quantum many body systems. In particular, the high degree of control of experiment…
Coherent Interaction of a Single Fermion with a Small Bosonic Field
Sebastian Will, Thorsten Best, Simon Braun +2
We have experimentally studied few-body impurity systems consisting of a single fermionic atom and a small bosonic field on the sites of an optical lattice. Quantum phase revival s…
Effect of interactions on harmonically confined Bose-Fermi mixtures in optical lattices
Michiel Snoek, Irakli Titvinidze, Immanuel Bloch +1
We investigate a Bose-Fermi mixture in a three-dimensional optical lattice, trapped in a harmonic potential. Using Generalized Dynamical Mean-Field theory, which treats the Bose-Bo…
