Reinterpreting dark energy through backreaction: the minimally coupled morphon field
Julien Larena, Thomas Buchert, Jean-Michel Alimi
In the context of averaged cosmologies, the effective equations can be written in the form of "regional" Friedmannian equations with additional sources arising from the so-called b…
The effect of sample properties on the electron velocity in quantum Hall bars
D. Eksi, E. Cicek, A. I. Mese +3
We report on our theoretical investigation of the effects of the confining potential profile and sample size on the electron velocity distribution in (narrow) quantum-Hall systems.…
Generic principles of active transport
Mauro Mobilia, Tobias Reichenbach, Hauke Hinsch +2
Nonequilibrium collective motion is ubiquitous in nature and often results in a rich collection of intringuing phenomena, such as the formation of shocks or patterns, subdiffusive…
Proton Threshold States in the 22Na(p,gamma)23Mg Reaction and Astrophysical Implications
H. Comisel, C. Hategan, G. Graw +1
Proton threshold states in 23Mg are important for the astrophysically relevant proton capture reaction 22Na(p,gamma)23Mg. In the indirect determination of the resonance strength of…
Effective action and heat kernel in a toy model of brane-induced gravity
A. O. Barvinsky, A. Yu. Kamenshchik, C. Kiefer +1
We apply a recently suggested technique of the Neumann-Dirichlet reduction to a toy model of brane-induced gravity for the calculation of its quantum one-loop effective action. Thi…
Inclusive Production of Charged Hadrons in Photon-Photon Collisions
The OPAL collaboration
The inclusive production of charged hadrons in the collisions of quasi-real photons e+e- -> e+e- +X has been measured using the OPAL detector at LEP. The data were taken at e+e- ce…
Phase lapses in transmission through interacting two-level quantum dots
C. Karrasch, T. Hecht, A. Weichselbaum +3
We investigate the appearance of pi lapses in the transmission phase theta of a two-level quantum dot with Coulomb interaction U. Using the numerical and functional renormalization…
Measurement of the ppbar to ttbar production cross section at sqrt(s)=1.96 TeV in the fully hadronic decay channel
D0 Collaboration, V. Abazov
A measurement of the top quark pair production cross section in proton anti-proton collisions at an interaction energy of sqrt(s)=1.96 TeV is presented. This analysis uses 405 pb-1…
Sequential Generation of Matrix-Product States in Cavity QED
C. Schoen, K. Hammerer, M. M. Wolf +2
We study the sequential generation of entangled photonic and atomic multi-qubit states in the realm of cavity QED. We extend the work of C. Schoen et al. [Phys. Rev. Lett. 95, 1105…
Design considerations for table-top, laser-based VUV and X-ray free electron lasers
F. Grüner, S. Becker, U. Schramm +12
A recent breakthrough in laser-plasma accelerators, based upon ultrashort high-intensity lasers, demonstrated the generation of quasi-monoenergetic GeV-electrons. With future Petaw…
Einstein-Riemann Gravity on Deformed Spaces
Julius Wess
A differential calculus, differential geometry and the E-R Gravity theory are studied on noncommutative spaces. Noncommutativity is formulated in the star product formalism. The ba…
Search for techniparticles in e +jets events at D0
D0 Collaboration, V. Abazov
We search for the technicolor process ppbar -> rho_T/omega_T ->W+pi_T in events containing one electron and two jets, in data corresponding to an integrated luminosity of 390 pb-1,…
Optimal control of a qubit coupled to a non-Markovian environment
P. Rebentrost, I. Serban, T. Schulte-Herbrueggen +1
A central challenge for implementing quantum computing in the solid state is decoupling the qubits from the intrinsic noise of the material. We investigate the implementation of qu…
Introduction to decoherence theory
Klaus Hornberger
This is an introduction to the theory of decoherence with an emphasis on its microscopic origins and on a dynamic description. The text corresponds to a chapter soon to be publishe…
Monitoring approach to open quantum dynamics using scattering theory
Klaus Hornberger
It is shown how S-matrix theory and the concept of continuous quantum measurements can be combined to yield Markovian master equations which describe the environmental interaction…
Black hole entropy functions and attractor equations
G. L. Cardoso, B. de Wit, S. Mahapatra
The entropy and the attractor equations for static extremal black hole solutions follow from a variational principle based on an entropy function. In the general case such an entro…
Glueballs vs. Gluinoballs: Fluctuation Spectra in Non-AdS/Non-CFT
Marcus Berg, Michael Haack, Wolfgang Muck
Building on earlier results on holographic bulk dynamics in confining gauge theories, we compute the spin-0 and spin-2 spectra of gauge theories dual to the non-singular Maldacena-…
Non-perturbative SQCD Superpotentials from String Instantons
Nikolas Akerblom, Ralph Blumenhagen, Dieter Lust +2
The Affleck-Dine-Seiberg instanton generated superpotential for SQCD with Nf=Nc-1 flavours is explicitly derived from a local model of engineered intersecting D6-branes with a sing…
Search for single production of scalar leptoquarks in p\bar{p} collisions decaying into muons and quarks with the D0 detector
D0 Collaboration, V. Abazov
We report on a search for second generation leptoquarks LQ_2 which decay into a muon plus quark in p\bar{p} collisions at a center-of-mass energy of sqrt{s} = 1.96 TeV in the D0 de…
Statistical properties of a sample of periodically variable B-type supergiants - Evidence for opacity-driven gravity-mode oscillations
K. Lefever, J. Puls, C. Aerts
We have studied a sample of 28 periodically variable B-type supergiants selected from the HIPPARCOS mission and 12 comparison stars covering the whole B-type spectral range. Our go…
