MovieMaker: A Parallel Movie-Making Software for Large Scale Simulations

We have developed a parallel rendering software for scientific visualization of large-scale, three-dimensional, time development simulations. The goal of this software, MovieMaker, is to generate a movie, or a series of visualization images from totally one TB-scale data within one night (or less than 12 hours). The isocontouring, volume rendering, and streamlines are implemented. MovieMaker is a parallel program for the shared memory architecture with dynamic load balancing and overlapped disk I/O.

Behavior of monopole trajectories in the instanton and anti-instanton system at finite temperature

We study the connection between monopoles and instantons in the Polyakov-like gauge, and the behavior of the monopole trajectories generated by instantons at finite temperature. The monopole trajectories become long and complicated at the zero-temperature which can be regarded as monopole condensation. On the other hand, they tend to become simple at finite temperature. It is suggested that such a change is related to the confinement-deconfinement phase transition.

Dual Higgs Mechanism and Nonperturbative QCD

We study the dual Higgs mechanism for the nonperturbative QCD. We point out two kind of the ``see-saw'' relations between electric and magnetic sectors. Owing to the Dirac condition $eg=4π$, the dual Ginzburg-Landau theory has the asymptotic freedom nature on the gauge coupling constant $e$, where the ``walking coupling constant'' is predicted for $e$ in the infrared region. We study also QCD-monopoles and instantons, which are two relevant topological objects in QCD. Strong correlations between the QCD-monopole trajectory and the topological charge are found both in the continuum theory and in the lattice gauge theory.
