Front propagation into unstable and metastable states in Smectic C* liquid crystals: linear and nonlinear marginal stability analysis
Wim van Saarloos, Martin van Hecke, Robert Holyst
We discuss the front propagation in ferroelectric chiral smectics (SmC*) subjected to electric and magnetic fields applied parallel to smectic layers. The reversal of the electric…
Sphinx: Monte Carlo Program for Polarised Nucleon-Nucleon Collisions
S. Guellenstern, P. Gornicki, L. Mankiewicz +1
This program can be used to simulate polarised nucleon - nucleon collisions at high energies. Spins of colliding particles are taken into account. The program allows to calculate c…
Monte Carlo Simulations for RHIC Spin Physics
S. Guellenstern, P. Gornicki, L. Mankiewicz +1
Direct photon production in longitudinally polarised proton-proton collisions offers the most direct and unproblematic possibility to determine the polarised gluon distribution of…
Ioffe-time distributions instead of parton momentum distributions in description of deep inelastic scattering
V. Braun, P. Górnicki, L. Mankiewicz
We argue that parton distributions in coordinate space provide a more natural object for nonperturbative methods compared to the usual momentum distributions in which the physics o…
QCD Sum Rule Calculation of Twist-3 Contributions to Polarized Nucleon Structure Functions
E. Stein, P. Gornicki, L. Mankiewicz +2
Using the framework of QCD sum rules we predict the twist-3 contribution to the second moment of the polarized nucleon structure function . As the relevant local operator d…
Iterations of rational functions: which hyperbolic components contain polynomials?
Feliks Przytycki
Let be the set of all rational maps of degree on the Riemann sphere which are expanding on Julia set. We prove that if and all or all but one critical poi…
