Fano resonances and decoherence in transport through quantum dots
S. Rotter, U. Kuhl, F. Libisch +2
A tunable microwave scattering device is presented which allows the controlled variation of Fano line shape parameters in transmission through quantum billiards. We observe a non-m…
Comments on the question of the discovery of element 112 as early as 1971
R. Brandt
There are two independent claims for the discovery of element 112: The claim by Hofmann et al. from 1996 and the older claim from 1971 by Marinov et al. This Comment will not chall…
The Chemical Separation of Eka-Hg from CERN W Targets in view of Recent Relativistic Calculations
D. Kolb, A. Marinov, G. W. A. Newton +1
In 1971 evidence for the production of element 112 via secondary reactions in CERN W targets was obtained. The evidence was mainly based on the observation of fission fragments in…
Experimental verification of fidelity decay: From perturbative to Fermi Golden Rule regime
R. Schaefer, T. Gorin, T. H. Seligman +1
The scattering matrix was measured for a flat microwave cavity with classically chaotic dynamics. The system can be perturbed by small changes of the geometry. We define the "scatt…
Signatures of Dynamical Tunneling in the Wave function of a Soft-Walled Open Microwave Billiard
Y. -H. Kim, U. Kuhl, H. -J. Stockmann +1
Evidence for dynamical tunneling is observed in studies of the transmission, and wave functions, of a soft-walled microwave cavity resonator. In contrast to previous work, we ident…
Observation of different azimuthal emission patterns for K+ and of K- mesons in Heavy Ion Collisions at 1-2 AGeV
F. Uhlig, A. Foerster, I. Boettcher +18
Azimuthal distributions of pi+, K+ and K- mesons have been measured in Au+Au reactions at 1.5 AGeV and Ni+Ni reactions at 1.93 AGeV. In semi-central collisions at midrapidity, pi+…
Phase Diagram of the ------ Model at Quarter Filling
Satoshi Ejima, Florian Gebhard, Satoshi Nishimoto +1
We examine the ground-state properties of the one-dimensional Hubbard model at quarter filling with Coulomb interactions between nearest-neighbors and next-nearest neighbors…
Complexes of graphs with bounded matching size
Svante Linusson, John Shareshian, Volkmar Welker
For positive integers k,n, we investigate the simplicial complex NM_k(n) of all graphs G on vertex set [n] such that every matching in G has size less than k. This complex (along w…
The ALPS project: open source software for strongly correlated systems
F. Alet, P. Dayal, A. Grzesik +15
We present the ALPS (Algorithms and Libraries for Physics Simulations) project, an international open source software project to develop libraries and application programs for the…
System Size and Centrality Dependence of the Balance Function in A + A Collisions at s(NN)^(1/2) = 17.2 GeV
NA49 Collaboration
Electric charge correlations were studied for p+p, C+C, Si+Si and centrality selected Pb+Pb collisions at GeV with the NA49 large acceptance detector at the…
Multiplicity fluctuations in nuclear collisions at 158 A GeV
M Rybczynski
System size dependence of multiplicity fluctuations of charged particles produced in nuclear collisions at 158 A GeV was studied in the NA49 CERN experiment. Results indicate a non…
Photoluminescence and Terahertz Emission from Femtosecond Laser-Induced Plasma Channels
W. Hoyer, J. V. Moloney, E. M. Wright +3
Luminescence as a mechanism for terahertz emission from femtosecond laser-induced plasmas is studied. By using a fully microscopic theory, Coulomb scattering between electrons and…

Using supersymmetry techniques analytical expressions for the average of the fidelity amplitude f_epsilon(tau)=< psi(0)| exp(2 pi i H_epsilon tau) exp(-2 pi i H_0 tau)| psi(0) > ar…
Lagrangian tracers on a surface flow: the role of time correlations
Guido Boffetta, Jahanshah Davoudi, Bruno Eckhardt +1
Finite time correlations of the velocity in a surface flow are found to be important for the formation of clusters of Lagrangian tracers. The degree of clustering characterized by…
Measurement of long-range wavefunction correlations in an open microwave billiard
Y. -H. Kim, U. Kuhl, H. -J. Stöckmann +1
We investigate the statistical properties of wavefunctions in an open chaotic cavity. When the number of channels in the openings of the billiard is increased by varying the freque…
