Measuring finite-range phase coherence in an optical lattice using Talbot interferometry
Bodhaditya Santra, Christian Baals, Ralf Labouvie +3
One of the important goals of present research is to control and manipulate coherence in a broad variety of systems, such as semiconductor spintronics, biological photosynthetic sy…
Quasiclassical analysis of Bloch oscillations in non-Hermitian tight-binding lattices
E M Graefe, H J Korsch, A Rush
Many features of Bloch oscillations in one-dimensional quantum lattices with a static force can be described by quasiclassical considerations for example by means of the accelerati…
Computations in quantum mechanics made easy
H J Korsch, K Rapedius
Convenient and simple numerical techniques for performing quantum computations based on matrix representations of Hilbert space operators are presented and illustrated by various e…
Single atom detection in ultracold quantum gases: a review of current progress
Herwig Ott
The recent advances in single atom detection and manipulation in experiments with ultracold quantum gases are reviewed. The discussion starts with the basic principles of trapping,…
Complex Squeezing and Force Measurement Beyond the Standard Quantum Limit
L. F. Buchmann, S. Schreppler, J. Kohler +2
A continuous quantum field, such as a propagating beam of light, may be characterized by a squeezing spectrum that is inhomogeneous in frequency. We point out that homodyne detecto…
Robust population transfer in atomic beams induced by Doppler shifts
R. G. Unanyan
The influence of photon-momentum recoil on adiabatic population transfer in an atomic three-level lambda system is studied. It is shown that the Doppler frequency shifts, due to at…
