Cluster Computing and the Power of Edge Recognition
Lane A. Hemaspaandra, Christopher M. Homan, Sven Kosub
We study the robustness--the invariance under definition changes--of the cluster class CL#P [HHKW05]. This class contains each #P function that is computed by a balanced Turing mac…
Reduction of the ordered magnetic moment in YMnO3 with hydrostatic pressure
M. Janoschek, B. Roessli, L. Keller +3
YMnO3 exhibits a ferroelectric transition at high temperature (~ 900 K) and magnetic ordering at T_N ~ 70 K where the dielectric constant shows an anomaly indicative of the magneto…
Statics and Dynamics of Strongly Charged Soft Matter
H. Boroudjerdi, Y. -W. Kim, A. Naji +3
Soft matter materials, such as polymers, membranes, proteins, are often electrically charged. This makes them water soluble, which is of great importance in technological applicati…
Theoretical Approaches to Neutral and Charged Polymer Brushes
Ali Naji, Christian Seidel, Roland R. Netz
Neutral or charged polymers that are densely end-grafted to surfaces form brush-like structures and are highly stretched under good-solvent conditions. We discuss and compare relev…
Scaling and Universality in the Counterion-Condensation Transition at Charged Cylinders
Ali Naji, Roland R. Netz
We address the critical and universal aspects of counterion-condensation transition at a single charged cylinder in both two and three spatial dimensions using numerical and analyt…
Flavor Symmetry L_mu - L_tau and quasi-degenerate Neutrinos
W. Rodejohann, M. A. Schmidt
Current data implies three simple forms of the neutrino mass matrix, each corresponding to the conservation of a non-standard lepton charge. While models based on L_e and L_e - L_m…
