Two Mode Photon Bunching Effect as Witness of Quantum Criticality in Circuit QED
Qing Ai, Ying-Dan Wang, Guilu Long +1
We suggest a scheme to probe critical phenomena at a quantum phase transition (QPT) using the quantum correlation of two photonic modes simultaneously coupled to a critical system.…
Unexpected finite-bias visibility dependence in an electronic Mach Zehnder interferometer
E. Bieri, M. Weiss, O. Goktas +4
We use an electronic Mach-Zehnder interferometer to explore the non-equilibrium coherence of the electron waves within the edge-states that form in the integral quantum Hall effect…
Contact resistance dependence of crossed Andreev reflection
A. Kleine, A. Baumgartner, J. Trbovic +1
We show experimentally that in nanometer scaled superconductor/normal metal hybrid devices and in a small window of contact resistances, crossed Andreev reflection (CAR) can domina…
Measurement of the Slope Parameter for the decay with the Crystal Ball detector at the Mainz Microtron (MAMI-C)
S. Prakhov, B. M. K. Nefkens, P. Aguar-Bartolome +68
The dynamics of the decay have been studied with the Crystal Ball multiphoton spectrometer and the TAPS calorimeter. Bremsstrahlung photons produced by the 1.5-GeV elec…
Cooling a micro-mechanical resonator by quantum back-action from a noisy qubit
Ying-Dan Wang, Yong Li, Fei Xue +2
We study the role of qubit dephasing in cooling a mechanical resonator by quantum back-action. With a superconducting flux qubit as a specific example, we show that ground-state co…
Probing Quark-Gluon Interactions with Transverse Polarized Scattering
K. Slifer, O. A. Rondon, A. Aghalaryan +69
We have extracted QCD matrix elements from our data on double polarized inelastic scattering of electrons on nuclei. We find the higher twist matrix element \tilde{d_2}, which aris…
Interference of heavy holes in an Aharonov-Bohm ring
Dimitrije Stepanenko, Minchul Lee, Guido Burkard +1
We study the coherent transport of heavy holes through a one-dimensional ring in the presence of spin-orbit coupling. Spin-orbit interaction of holes, cubic in the in-plane compone…
Measurement of the pn -> dK^+K^- total cross section close to threshold
Y. Maeda, M. Hartmann, I. Keshelashvili +20
Measurements of the pn -> p_spec dK^+K^- reaction, where p_spec is a spectator proton, have been undertaken at the Cooler Synchrotron COSY-Juelich by detecting a fast deuteron in c…
Application of Multihomogeneous Covariants to the Essential Dimension of Finite Groups
Roland Lötscher
We investigate essential dimension of finite groups over arbitrary fields and give a systematic treatment of multihomogenization, introduced by H.Kraft, G.Schwarz and the author. W…
Entropy inference and the James-Stein estimator, with application to nonlinear gene association networks
Jean Hausser, Korbinian Strimmer
We present a procedure for effective estimation of entropy and mutual information from small-sample data, and apply it to the problem of inferring high-dimensional gene association…
Dynamics of the inhomogeneous Dicke model
Oleksandr Tsyplyatyev, Daniel Loss
We study the time dynamics of a single boson coupled to a bath of two-level systems (spins 1/2) with different excitation energies, described by an inhomogeneous Dicke model. Analy…
Momentum dependence of the spin susceptibility in two dimensions: nonanalytic corrections in the Cooper channel
Stefano Chesi, Robert Andrzej Żak, Pascal Simon +1
We consider the effect of rescattering of pairs of quasiparticles in the Cooper channel resulting in the strong renormalization of second-order corrections to the spin susceptibili…
The Impact of Uncertainties in Reaction Q-values on Nucleosynthesis in Type I X-Ray Bursts
A. Parikh, J. Jose, C. Iliadis +2
Nucleosynthesis in Type I X-ray bursts may involve up to several thousand nuclear processes. The majority of these processes have only been determined theoretically due to the lack…
Interplay between interference and Coulomb interaction in the ferromagnetic Anderson model with applied magnetic field
Jonas Nyvold Pedersen, Dan Bohr, Andreas Wacker +3
We study the competition between interference due to multiple single-particle paths and Coulomb interaction in a simple model of an Anderson-like impurity with local-magnetic-field…
Photoproduction of eta-mesons off nuclei for Eg < 2.2 GeV
T. Mertens, I. Jaegle, P. Muehlich +69
Photoproduction of mesons off C, Ca, Nb, and Pb nuclei has been measured with a tagged photon beam with energies between 0.6 and 2.2 GeV. The exper…
Finite field theories and causality
Andreas Aste
A condensed introduction to the basic concepts of causal perturbation theory is given. Causal perturbation theory is a mathematically rigorous approach to renormalization theory, w…
The performance of Minima Hopping and Evolutionary Algorithms for cluster structure prediction
Sandro E. Schoenborn, Stefan Goedecker, Shantanu Roy +1
We compare Evolutionary Algorithms with Minima Hopping for global optimization in the field of cluster structure prediction. We introduce a new {\em average offspring} recombinatio…

At the electron accelerator ELSA a linearly polarised tagged photon beam is produced by coherent bremsstrahlung off a diamond crystal. Orientation and energy range of the linear po…
