Spectra and ground states of one- and two-dimensional laser-driven lattices of ultracold Rydberg atoms
Spectra ground states one- and two-dimensional laser-driven lattices ultracold Rydberg atoms
2012/2/28
We investigate static properties of laser-driven, ultracold Rydberg atoms confined to one- and two-dimensional uniform lattices in the limit of vanishing laser coupling. The spectral structure of squa...
Guiding of Rydberg atoms in a high-gradient magnetic guide
Guiding Rydberg atoms high-gradient magnetic guide
2012/2/28
We study the guiding of $^{87}$Rb 59D$_{5/2}$ Rydberg atoms in a linear, high-gradient, two-wire magnetic guide. Time delayed microwave ionization and ion detection are used to probe the Rydberg atom ...
We propose blue-detuned optical traps that are suitable for trapping of both ground state and Rydberg excited atoms. Addition of a background compensation field or suitable choice of the trap geometry...
Interaction-induced stabilization of circular Rydberg atoms
Interaction-induced stabilization circular Rydberg atoms
2011/9/9
We discuss a candidate solution for the controlled trapping and manipulation of two individual Rydberg atoms by means of a magnetic Io e-Pritchard trap that is superimposed by a constant electric eld...
Phase diagram of Rydberg atoms with repulsive van der Waals interaction
Phase diagram of Rydberg atoms
2011/9/14
We report a quantum Monte Carlo calculation of the phase diagram of bosons interacting with a repulsive inverse sixth power pair potential, a model for assemblies of Rydberg atoms in the local van der...
AC-Stark shift and photoionization of Rydberg atoms in an optical dipole trap
AC-Stark shift photoionization Rydberg atoms
2010/11/12
We have measured the AC-Stark shift of the $14D_{5/2}$ Rydberg state of rubidium 87 in an optical dipole trap formed by a focussed CO$_2$-laser. We find good quantitative agreement with the model of ...
Collective photon emission from symmetric states created with Rydberg atoms on a ring lattice
Collective photon emission symmetric states Rydberg atoms
2010/10/21
We discuss the creation of non-classical light from collective atomic states that are prepared in a ring-shaped lattice. These states are realized by exploiting the strong interaction between atoms in...
Stark-tuned Förster resonance and dipole blockade between 2 to 5 cold Rydberg atoms: Monte-Carlo simulations for various spatial configurations

2010/10/18
Results of the numerical Monte-Carlo simulations for the Stark-tuned F¨orster resonance and dipole blockade between 2 to 5 cold rubidium Rydberg atoms in various spatial configurations are presented.E...
Semiunitary transformation is applied to discuss supersymmetrization of cold Rydberg atoms. In the limit of vanishing kinetic energy the lowest angular momentum of the supersymmetric cold Rydberg atom...
