High-Performance Computing at the Center

The High-Performance Computing Cluster of the Center of Theoretical Physics provides faculty and students computational power for research and education 24 hours 7 days a week. The numerical research conducted on the Cluster includes:
  • Condensed Matter Physics

    1. Light-matter interaction with the focus on quantum transport phenomena in low-dimensional semiconductor nanostructures and graphene, including nonlinear exciton and polariton dynamics
    2. Computer-assisted search for novel dielectric materials for energy storage
    3. Development of new technologies for optical modulators and waveguides, including graphene-based photonic crystals
    4. Bose-Einstein condensates of ultra-cold Rydberg atoms

    Exciton BEC turbulence Polariton switch

    Left: Formation of a turbulent exciton Bose-Einstein condensate in coupled semiconductor quantum wells. Right: Computational design of a graphene-based polariton switch.

  • High-Energy Physics

    1. Automated Feynman diagram calculations
    2. Computer algebra

    Top quark production Diagrams

    Left: Picture illustrating top quark pair production. Right: Pentabox integrand decomposition for two-loop scattering amplitude.

  • Astrophysics

    1. Hydrodynamic approach in modeling of the galaxies formation
    2. Monte-Carlo analysis of the spectral energy distribution of galaxies, devising GalMC code

    Galaxy Galaxy Galaxy

    Formation of a galaxy from the interstellar gas. Left: The color shows the gas density, with the densest object being the main galaxy. The box is 400 kiloparsec in size. Center: Same picture but now zoomed in on the main galaxy. The box is 70 kiloparsec in size. Right: Phase plot of temperature versus density with the color indicating the total amount of mass with those values. This graph is for a sphere centered around the main galaxy with radius 250 kiloparsec. The simulations have been run with the adaptive mesh refinement code Enzo.
