Precision Measurement of Gravity with Cold Atoms in an Optical Lattice and Comparison with a Classical Gravimeter
TL;DR: A precision measurement of gravitational acceleration using ultracold strontium atoms confined in an amplitude-modulated vertical optical lattice is reported, consistent with the one measured with a classical gravimeter.
Coherent Delocalization of Atomic Wave Packets in Driven Lattice Potentials
V. V. Ivanov,Andrea Alberti,Marco Schioppo,Gabriele Ferrari,Maurizio Artoni,Maria Luisa Chiofalo,Guglielmo M. Tino +6 more
TL;DR: Atomic wave packets loaded into a phase-modulated vertical optical-lattice potential exhibit a coherent delocalization dynamics arising from intraband transitions among Wannier-Stark levels, observed by monitoring the in situ wave-packet extent.
Molecular binding in interacting quantum walks
Andre Ahlbrecht,Andrea Alberti,Dieter Meschede,Volkher B. Scholz,Volkher B. Scholz,Albert H. Werner,Reinhard F. Werner +6 more
TL;DR: In this paper, it was shown that the presence of an interaction in the quantum walk of two atoms leads to the formation of a stable compound, a molecular state The wave function of the molecule decays exponentially in the relative position of the two atoms; hence it constitutes a true bound state.

Propagation of Quantum Walks in Electric Fields
TL;DR: This work studies one-dimensional quantum walks in a homogenous electric field and relates the long time propagation properties of this system to the continued fraction expansion of the field.
Super-resolution microscopy of single atoms in optical lattices
Andrea Alberti,Carsten Robens,Wolfgang Alt,Stefan Brakhane,Michał Karski,René Reimann,Artur Widera,Dieter Meschede +7 more
TL;DR: In this article, a deconvolution method was proposed to determine the lattice-site positions of single atoms in an optical lattice with high reliability, even for limited acquisition time or optical resolution.
