Collective Rydberg excitations of an atomic gas confined in a ring lattice
B. Olmos, R. González-Férez, I. Lesanovsky
We study the excitation dynamics of Rydberg atoms in a one-dimensional lattice with periodic boundary conditions where the atomic Rydberg states are resonantly excited from the ele…
Interference of interacting matter waves
Mattias Gustavsson, Elmar Haller, Manfred J. Mark +4
The phenomenon of matter wave interference lies at the heart of quantum physics. It has been observed in various contexts in the limit of non-interacting particles as a single part…
Observation of interspecies Feshbach resonances in an ultracold Rb-Cs mixture
K. Pilch, A. D. Lange, A. Prantner +4
We report on the observation of interspecies Feshbach resonances in an ultracold, optically trapped mixture of Rb and Cs atoms. In a magnetic field range up to 300 G we find 23 int…
Entanglement and permutational symmetry
Geza Toth, Otfried Gühne
We study the separability of permutationally symmetric quantum states. We show that for bipartite symmetric systems most of the relevant entanglement criteria coincide. However, we…
Alkaline-Earth-Metal Atoms as Few-Qubit Quantum Registers
Alexey V. Gorshkov, Ana Maria Rey, Andrew J. Daley +4
We propose and analyze a novel approach to quantum information processing, in which multiple qubits can be encoded and manipulated using electronic and nuclear degrees of freedom a…
A classical explanation of quantization
Gerhard Groessing, Johannes Mesa Pascasio, Herbert Schwabl
In the context of our recently developed emergent quantum mechanics, and, in particular, based on an assumed sub-quantum thermodynamics, the necessity of energy quantization as ori…
