Out-of-core singular value decomposition
Vadim Demchik, Miroslav Bačák, Stefan Bordag
Singular value decomposition (SVD) is a standard matrix factorization technique that produces optimal low-rank approximations of matrices. It has diverse applications, including ma…
Spontaneous symmetry breaking in the O(4) scalar model on a lattice
Vadim Demchik, Alexey Gulov, Vladimir Skalozub
The spontaneous symmetry breaking at zero temperature in the four-component four-dimensional scalar model (the O(4) model) is investigated on a lattice for different value…
Increasing precision of uniform pseudorandom number generators
Vadim Demchik, Alexey Gulov
A general method to produce uniformly distributed pseudorandom numbers with extended precision by combining two pseudorandom numbers with lower precision is proposed. In particular…
QCDGPU: open-source package for Monte Carlo lattice simulations on OpenCL-compatible multi-GPU systems
Vadim Demchik, Natalia Kolomoyets
The multi-GPU open-source package QCDGPU for lattice Monte Carlo simulations of pure SU(N) gluodynamics in external magnetic field at finite temperature and O(N) model is developed…
Spontaneous generation of chromomagnetic fields at finite temperature in the SU(3) gluodynamics on a lattice
Vadim Demchik, Alexey Gulov, Natalia Kolomoyets
The spontaneous generation of homogeneous chromomagnetic fields in the lattice SU(3) gluodynamics is investigated in the deconfinement phase of the model. A new approach based on d…
Spontaneous magnetization of a vacuum in the hot Universe and intergalactic magnetic fields
Vadim Demchik, Vladimir Skalozub
We review the spontaneous magnetization of the vacuum of non-Abelian gauge fields at high temperature. The standard model of particles is investigated as a particular example. By u…
