Solution of the two-center Dirac equation with 20 digits precision using the finite-element technique
O. Kullie, S. Schiller
We present a precise fully relativistic numerical solution of the two-center Coulomb problem. The special case of unit nuclear charges is relevant for the accurate description of t…
Proton-electron mass ratio by high-resolution optical spectroscopy of ion ensembles in the resolved-carrier regime
I. V. Kortunov, S. Alighanbari, M. G. Hansen +3
Optical spectroscopy in the gas phase is a key tool to elucidate the structure of atoms and molecules and of their interaction with external fields. The line resolution is usually…
Rotational spectroscopy of cold, trapped molecular ions in the Lamb-Dicke regime
Soroosh Alighanbari, Michael Georg Hansen, Vladimir Korobov +1
Sympathetic cooling of trapped ions has been established as a powerful technique for manipulation of non-laser-coolable ions (Raizen1992,Waki1992,Bowe1999,Barrett2003). For molecul…
A simple method for characterization of the magnetic field in an ion trap using Be+ ions
Jianwei Shen, Andrii Borodin, Stephan Schiller
We demonstrate a simple method for the determination of the magnetic field in an ion trap using laser-cooled Be+ ions. The method is not based on magnetic resonance and thus does n…
Observation of a rotational transition in trapped and sympathetically cooled molecular ions
J. Shen, A. Borodin, M. Hansen +1
We demonstrate rotational excitation of molecular ions that are sympathetically cooled by laser-cooled atomic ions to a temperature as low as ca. 10 mK. The molecular hydrogen ions…
Thermal noise of whispering gallery resonators
Akobuije Chijioke, Qun-Feng Chen, Alexander Yu. Nevsky +1
By direct application of the fluctuation-dissipation theorem, we numerically calculate the fundamental dimensional fluctuations of crystalline CaF2 whispering gallery resonators in…
Sympathetically cooled molecular ions: from principles to first applications
Bernhard Roth, Stephan Schiller
We review the current status of the field of sympathetically cooled molecular ions, i.e. the method used for cooling the translational degrees of freedom, the techniques applied fo…
Molecular Dynamics Simulation of Sympathetic Crystallization of Molecular Ions
S. Schiller, C. Laemmerzahl
It is shown that the translational degrees of freedom of a large variety of molecules, from light diatomic to heavy organic ones, can be cooled sympathetically and brought to rest…
Quantum state reconstruction of the single-photon Fock state
A. I. Lvovsky, H. Hansen, T. Aichele +3
We have reconstructed the quantum state of optical pulses containing single photons using the method of phase-randomized pulsed optical homodyne tomography. The single-photon Fock…
Broadband detection of squeezed vacuum: A spectrum of quantum states
Gerd Breitenbach, Fabrizio Illuminati, Stephan Schiller +1
We demonstrate the simultaneous quantum state reconstruction of the spectral modes of the light field emitted by a continuous wave degenerate optical parametric amplifier. The sche…
Homodyne measurement of exponential phase moments for quantum-phase reconstruction
M. Dakna, G. Breitenbach, J. Mlynek +3
We directly sample the exponential moments of the canonical phase for various quantum states from the homodyne output. The method enables us to study the phase properties experimen…
