Steady-state crystallization of Rydberg excitations in an optically driven lattice gas
Michael Hoening, Dominik Muth, David Petrosyan +1
We study resonant optical excitations of atoms in a one-dimensional lattice to the Rydberg states interacting via the van der Waals potential which suppresses simultaneous excitati…
Entanglement measures and the quantum to classical mapping
J. Sirker
A quantum model can be mapped to a classical model in one higher dimension. Here we introduce a finite-temperature correlation measure based on a reduced density matrix rho_A obtai…
Bayesian feedback control of a two-atom spin-state in an atom-cavity system
Stefan Brakhane, Wolfgang Alt, Tobias Kampschulte +5
We experimentally demonstrate real-time feedback control of the joint spin-state of two neutral Caesium atoms inside a high finesse optical cavity. The quantum states are discrimin…
Interaction-induced decoherence in non-Hermitian quantum walks of ultracold Bosons
K. Rapedius, H. J. Korsch
We study the influence of particle interaction on a quantum walk on a bipartite one-dimensional lattice with decay from every second site. The corresponding non-interacting (linear…
Back-reaction of perturbation wave packets on gray solitons
P. B. Walczak, J. R. Anglin
Within the Bogoliubov-de Gennes linearization theory of quantum or classical perturbations around a background solution to the one-dimensional nonlinear Schrödinger equation, we st…
Transport induced melting of crystals of Rydberg dressed atoms in a one dimensional lattice
Achim Lauer, Dominik Muth, Michael Fleischhauer
We discuss the many-body physics of an ensemble of Rydberg dressed atoms with van der Waals dipole-dipole interactions in a one-dimensional lattice. Using a strong coupling expansi…
