Approximating open quantum system dynamics in a controlled and efficient way: A microscopic approach to decoherence
Giulia Gualdi, Christiane P. Koch
We demonstrate that the dynamics of an open quantum system can be calculated efficiently and with predefined error, provided a basis exists in which the system-environment interact…
The Cox ring of the space of complete rank two collineations
Juergen Hausen, Michael Liebendoerfer
We determine the Cox ring of the space of complete rank two collineations.
ICP-SFMS search for long-lived naturally-occurring heavy, superheavy and superactinide nuclei compared to AMS experiments
A. Marinov, A. Pape, Y. Kashiv +4
Negative results obtained in AMS searches by Dellinger et al. on mostly unrefined ores have led them to conclude that the very heavy long-lived species found in chemically processe…
Symmetry-Breaking Phase Transition without Peierls Mechanism in Conducting Monoatomic Chains
C. Blumenstein, J. Schaefer, M. Morresi +3
The one-dimensional (1D) model system Au/Ge(001), consisting of linear chains of single atoms on a surface, is scrutinized for lattice instabilities predicted in the Peierls paradi…
Learning Concept Hierarchies from Text Corpora using Formal Concept Analysis
P. Cimiano, A. Hotho, S. Staab
We present a novel approach to the automatic acquisition of taxonomies or concept hierarchies from a text corpus. The approach is based on Formal Concept Analysis (FCA), a method m…
Generating Molecular Rovibrational Coherence by Two-Photon Femtosecond Photoassociation of Thermally Hot Atoms
Leonid Rybak, Saieswari Amaran, Liat Levin +5
The formation of diatomic molecules with rotational and vibrational coherence is demonstrated experimentally in free-to-bound two-photon femtosecond photoassociation of hot atoms.…
Algorithmic Proof of the Epsilon Constant Conjecture
Werner Bley, Ruben Debeerst
In this paper we will algorithmically prove the local and global epsilon constant conjectures for all fields of absolute degree lower or equal to 15. To this end we will present an…
Molecular imaging using high-order harmonic generation and above-threshold ionization
Elmar V. van der Zwan, Manfred Lein
Accurate molecular imaging via high-order harmonic generation relies on comparing the harmonic emission from a molecule and an adequate reference system. However, an ideal referenc…
Coherent strong-field control of multiple states by a single chirped femtosecond laser pulse
M Krug, T Bayer, M Wollenhaupt +4
We present a joint experimental and theoretical study on strong-field photo-ionization of sodium atoms using chirped femtosecond laser pulses. By tuning the chirp parameter, select…
Formation of ultracold SrYb molecules in an optical lattice by photoassociation spectroscopy: theoretical prospects
Michal Tomza, Filip Pawlowski, Malgorzata Jeziorska +2
State-of-the-art {\em ab initio} techniques have been applied to compute the potential energy curves for the SrYb molecule in the Born-Oppenheimer approximation for the ground stat…
Prospects for fast Rydberg gates on an atom chip
Matthias M. Müller, Harald R. Haakh, Tommaso Calarco +2
Atom chips are a promising candidate for a scalable architecture for quantum information processing provided a universal set of gates can be implemented with high fidelity. The dif…
The Quantum Speed Limit of Optimal Controlled Phasegates for Trapped Neutral Atoms
Michael H. Goerz, Tommaso Calarco, Christiane P. Koch
We study controlled phasegates for ultracold atoms in an optical potential. A shaped laser pulse drives transitions between the ground and electronically excited states where the a…
