At nanokelvin temperatures, ultracold quantum gases can be stored in optical lattices, which
are arrays of microscopic trapping potentials formed by laser light. Such large arrays of …

We experimentally realize a Peierls phase in the hopping amplitude of excitations carried by
Rydberg atoms, and observe the resulting characteristic chiral motion in a minimal setup of …

The result of a lecture series, this textbook is oriented towards students and newcomers to
the field and discusses theoretical foundations as well as experimental realizations in detail …

We present a setup with Rydberg atoms for the realization of a bosonic fractional Chern
insulator in artificial matter. The suggested setup relies on Rydberg atoms arranged in a …

We report on image processing techniques and experimental procedures to determine the
lattice-site positions of single atoms in an optical lattice with high reliability, even for limited …

Superradiance, ie, spontaneous emission of coherent radiation by an ensemble of two-level
atoms in collective states introduced by Dicke in 1954, is one of the enigmatic problems of …

We investigate the influence of a Bose–Einstein condensate (BEC) on the properties of
immersed impurity atoms, which are trapped in an optical lattice. Assuming a weak coupling …

We prepare arbitrary patterns of neutral atoms in a one-dimensional (1D) optical lattice with
single-site precision using microwave radiation in a magnetic field gradient. We give a …

We show the possibility of directional guided superradiance from a linear array of distant
atoms separated by one or several wavelengths in a line parallel to the axis of a nanofiber …

We develop a systematic formalism to calculate the correlation functions of fluorescence
from a multiatom system into guided modes of a nanofiber. We find that, in the case of a …
