Abstract In trilobite Rydberg molecules, an atom in the ground state is bound by electron-atom scattering to a Rydberg electron that is in a superposition of high angular momentum states. This results in a homonuclear molecule with a permanent electr

We experimentally study the level mixing, splitting and repulsion of an optically driven atomic multi-level system under two competing interactions. The strength of the optical coupling is increased until it surpasses the atomic hyperfine interaction

The spread of excitations by Rydberg facilitation bears many similarities to epidemics. Such systems can be modeled with Monte Carlo simulations of classical rate equations to great accuracy as a result of high dephasing. Motivated by experiments, we

Three-dimensional spin models with random hopping disorder are relevant to a large variety of physical systems. Here, the authors present an experimental realization of such a model in a Rydberg system with dipole-dipole coupling and show signatures

Here, the authors discuss state-changing inelastic collisions between rubidium Rydberg and ground state atoms. They employ high-resolution magneto-optical trap recoil-ion momentum spectroscopy to measure the distribution of the final states.

Quantum gas experiments are useful to study non-equilibrium many-body dynamics. Here, the authors demonstrate how the Talbot effect can be used to measure the spreading of phase coherence of ultracold atoms in an optical lattice.

Rydberg molecules have potential for ultracold chemistry applications in light of their unconventional binding mechanism that provides high tunability. Here the authors observe and control butterfly Rydberg molecules, which are bound by a shape reson

The truncated Wigner approximation is an established approach that describes the dynamics of weakly interacting Bose gases beyond the mean-field level. Although it allows a quantum field to be expressed by a stochastic c-number field, the simulation

Exploring the dynamics of inelastic and reactive collisions on the quantum level is a fundamental goal in quantum chemistry. Such collisions are of particular importance in connection with Rydberg atoms in dense environments since they may considerab
