Modulation of elasticity and interactions in charged lipid multibilayers: monovalent salt solutions
Bing-Sui Lu, Santosh Gupta, Michal Belička +2
We have studied the electrostatic screening effect of NaCl solutions on the interactions between anionic lipid bilayers in the fluid lamellar phase using a Poisson-Boltzmann based…
Influence of broken flavor and C and P symmetry on the quark propagator
Axel Maas, Walid Ahmed Mian
Embedding QCD into the standard model breaks various symmetries of QCD explicitly, especially C and P. While these effects are usually perturbatively small, they can be amplified i…
Gauge engineering and propagators
Axel Maas
Beyond perturbation theory gauge-fixing becomes more involved due to the Gribov-Singer ambiguity: The appearance of additional gauge copies requires to define a procedure how to ha…
Indications of stellar prominence oscillations on fast rotating stars: the cases of HK Aqr and PZ Tel
M. Leitzinger, P. Odert, T. V. Zaqarashvili +3
We present the analysis of six nights of spectroscopic monitoring of two young and fast rotating late-type stars, namely the dMe star HK Aqr and the dG/dK star PZ Tel. On both star…
Verification of high-speed solar wind stream forecasts using operational solar wind models
Martin A. Reiss, Manuela Temmer, Astrid M. Veronig +4
High-speed solar wind streams emanating from coronal holes are frequently impinging on the Earth's magnetosphere causing recurrent, medium-level geomagnetic storm activity. Modelin…
Baryons as relativistic three-quark bound states
Gernot Eichmann, Helios Sanchis-Alepuz, Richard Williams +2
We review the spectrum and electromagnetic properties of baryons described as relativistic three-quark bound states within QCD. The composite nature of baryons results in a rich ex…
