Large anisotropy of electron and hole g factors in infrared-emitting InAs/InAlGaAs self-assembled quantum dots
V. V. Belykh, D. R. Yakovlev, J. J. Schindler +6
A detailed study of the -factor anisotropy of electrons and holes in InAs/InAlGaAs self-assembled quantum dots emitting in the telecom spectral range…
Microscopy with a Deterministic Single Ion Source
Georg Jacob, Karin Groot-Berning, Sebastian Wolf +6
We realize a single particle microscope by using deterministically extracted laser cooled Ca ions from a Paul trap as probe particles for transmission imaging. We demons…
Tunneling time in attosecond experiments, Keldysh, Mandelstam-Tamm and intrinsic-type of time
Ossama Kullie
Tunneling time in attosecond and strong field experiments is one of the most controversial issues in today's research, because of its importance to the theory of time, the time ope…
Quantum optimal control of photoelectron spectra and angular distributions
R. Esteban Goetz, Antonia Karamatskou, Robin Santra +1
Photoelectron spectra and photoelectron angular distributions obtained in photoionization reveal important information on e.g. charge transfer or hole coherence in the parent ion.…
Target effects in negative-continuum assisted dielectronic recombination
V. A. Yerokhin, A. N. Artemyev, V. M. Shabaev +3
The process of recombination of a quasi-free electron into a bound state of an initially bare nucleus with the simultaneous creation of a bound-electron--free-positron pair is inve…
A single-atom heat engine
Johannes Roßnagel, Samuel Thomas Dawkins, Karl Nicolas Tolazzi +4
We report the experimental realization of a single-atom heat engine. An ion is confined in a linear Paul trap with tapered geometry and driven thermally by coupling it alternately…
Electron and hole g factors in InAs/InAlGaAs self-assembled quantum dots emitting at telecom wavelengths
V. V. Belykh, A. Greilich, D. R. Yakovlev +4
We extend the range of quantum dot (QD) emission energies where electron and hole factors have been measured to the practically important telecom range. The spin dynamics in In…
The Arity Hierarchy in the Polyadic -Calculus
Martin Lange
The polyadic mu-calculus is a modal fixpoint logic whose formulas define relations of nodes rather than just sets in labelled transition systems. It can express exactly the polynom…
Training Schrödinger's cat: quantum optimal control
Stefffen J. Glaser, Ugo Boscain, Tommaso Calarco +9
It is control that turns scientific knowledge into useful technology: in physics and engineering it provides a systematic way for driving a system from a given initial state into a…
Many-body theory of ultrafast demagnetization and angular momentum transfer in ferromagnetic transition metals
W. Töws, G. M. Pastor
Exact calculated time evolutions in the framework of a many-electron model of itinerant magnetism provide new insights into the laser-induced ultrafast demagnetization observed in…
Coherent control of bond making: The performance of rationally phase-shaped femtosecond laser pulses
Liat Levin, Wojciech Skomorowski, Ronnie Kosloff +2
The first step in the coherent control of a photoinduced binary reaction is bond making or photoassociation. We have recently demonstrated coherent control of bond making in multi-…
Hybrid Optimization Schemes for Quantum Control
Michael H. Goerz, K. Birgitta Whaley, Christiane P. Koch
Optimal control theory is a powerful tool for solving control problems in quantum mechanics, ranging from the control of chemical reactions to the implementation of gates in a quan…
Tunneling time in attosecond experiments and time-energy uncertainty relation
Ossama Kullie
In this work we present a theoretical model supported with a physical reasoning leading to a relation which performs an excellent estimation for the tunneling time in attosecond an…
Coherent Control of Photoelectron Wavepacket Angular Interferograms
Paul Hockett, Matthias Wollenhaupt, Thomas Baumert
Coherent control over photoelectron wavepackets, via the use of polarization-shaped laser pulses, can be understood as a time and polarization-multiplexed process. In this work, we…
Crystal growth kinetics in Lennard-Jones and Weeks-Chandler-Andersen systems along the solid-liquid coexistence line
Ronald Benjamin, Jürgen Horbach
Kinetics of crystal-growth is investigated along the solid-liquid coexistence line for the (100), (110) and (111) orientations of the Lennard-Jones and Weeks-Chandler-Andersen fcc…
A New Vision of Collaborative Active Learning
Adrian Calma, Tobias Reitmaier, Bernhard Sick +2
Active learning (AL) is a learning paradigm where an active learner has to train a model (e.g., a classifier) which is in principal trained in a supervised way, but in AL it has to…
Participatory Patterns in an International Air Quality Monitoring Initiative
Alina Sîrbu, Martin Becker, Saverio Caminiti +17
The issue of sustainability is at the top of the political and societal agenda, being considered of extreme importance and urgency. Human individual action impacts the environment…
Imaging an aligned polyatomic molecule with laser-induced electron diffraction
Michael Pullen, Benjamin Wolter, Anh-Thu Le +8
Laser-induced electron diffraction is an evolving tabletop method, which aims to image ultrafast structural changes in gas-phase polyatomic molecules with sub-Ångström spatial and…
The Responsibility Weighted Mahalanobis Kernel for Semi-Supervised Training of Support Vector Machines for Classification
Tobias Reitmaier, Bernhard Sick
Kernel functions in support vector machines (SVM) are needed to assess the similarity of input samples in order to classify these samples, for instance. Besides standard kernels su…
Experimental Observation of Resonance-Assisted Tunneling
Stefan Gehler, Steffen Löck, Susumu Shinohara +4
We present the first experimental observation of resonance-assisted tunneling, a wave phenomenon, where regular-to-chaotic tunneling is strongly enhanced by the presence of a class…
Predissociation dynamics of lithium iodide
H. Schmidt, J. von Vangerow, F. Stienkemeier +6
The predissociation dynamics of lithium iodide (LiI) in the first excited A-state is investigated for molecules in the gas phase and embedded in helium nanodroplets, using femtosec…
