Hello! I am Quann. This is my personal website and technology blogs. I have Ph.D Degree of applied mathematics and mathematical physics from University of Helsinki. And I have been closely worked with different experimental groups from Lancaster University, Royal Holloway University of London and Aalto University.

I have been worked and conducted scientific researches with HPC about superfluid of liquid Helium-3 over eight years. The topics of physics I’ve worked on and published papers are

  • String and monopole topological defects and composite topological defects in symmetry breaking system.
  • Phase transition dynamics simulations and formations of topological and non-topological defects.
  • Spin collective modes in P-wave superfluid and their Nuclear Magnetic Resonance (NMR) signals.
  • Pair density wave and spatial modulations of order parameters of p-wave superfluid.
  • Emergent gravitational physics in P-wave superfluid with Wyel points.

My researches massively take advantages of powerful modern computational hardwares available on High Performance Computing platform. The algorithms and technologies I used in my numerical simulation projects include

  • Adaptive meshed Finite Element methods with CPU parallelizatons on architecture with AVX2/AVX512 vectorization.
  • CPU and GPU (CUDA/ROCm) parallelized Finite difference methods of Langvevin equations with tensor-valued order. parameters.
  • CMake and GNU Make configurations and managements of complex source tree of HPC projects.
  • Parallel postprocessing of HPC data and insitu visualizations of HPC stream data.
  • Python scripts, UNIX shell scripts and Mathematica notebooks.
