Laboratory of Computer Simulations
Modelling of physical processes on computers links theoretical knowledge with experimental observations.
Students are welcome - projects offer numerous partial goals suitable for students' theses
Researchers and students focus on two directions of computer simulations:
1) Molecular simulations
We use equilibrium and non-equilibrium molecular dynamics (MD) to study interactions of molecules. Students study interactions of molecules with surfaces and adsorption of molecules, structure, dynamics and interactions of nucleic acids oligonucleotides and their building blocks.
When needed, these simulations are combined with ab initio quantum calculations, which yield interaction parameters used subsequently in molecular simulations of systems of sizes typically from thousands to hundred of thousands of atoms.
The results of simulations are being compared with theory (theory of electric double-layer), experiments (X-ray diffraction, surface titration, adsorption experiments, second harmonics generation) and quantum calculations (ab initio calculations, quantum dynamics).

Our numerical simulations are based on the solutions of magnetohydrodynamic (MHD) equations. In this case we simulate the plasma processes from macroscopic point of view, i.e. plasma is described as the conductive fluid. Our main scientific interest is focused on the problems related to the coronal heating, especially the plasma waves and oscillations which could significantly contribute to the heating of higher parts of solar atmosphere.
For computationally extensive physical and biophysical simulations we use two local computer clusters and national computational Metacentrum
11 machines in a rack, each 2x Quad Core Xeon E5345 @ 2.33 GHz, 16 GB RAM, 5 x 500 GB HDD, Debian GNU/Linux
This cluster is a member of Metacentrum, local users have privileged access..Cluster of Department of Physics and Biophysics:
7 PC , each Quad Core 2 Quad @ 3.0 GHz, 2 GB RAM, 500 GB HDD, SuSE 11 Linux + 2TB shared disk
1 PC Intel(R) Core(TM) i5-2310 CPU @ 2.90GHz, 500 GB HDD, SuSE 11 Linux, GPU GIGABYTE GTX 560 Ti Ultra Durable 1GBBoth clusters offer parallel environment for compilation and execution of multi-processor (multi-thread) tasks and are used in teaching of classes UFY/PPI Parallel programing, UFY/PFM Computational physics - Computer modeling, UFY/SIM1 Computer simulations in many body physics and UFY/SIM2 Advanced simulations in many body physics.

Laboratory of Acoustics and Electronics
The main aim of the Laboratory of Acoustic and Electronics is the sound signal processing. We cooperate with colleagues of IT Institute (UAI) and Faculty of Education (PF).
We also focus on sound and building design. The sound analyzers Bruel &Kjaer 2250 are used as well as other supplementary tools.
