Numerical Study of Scalar Field Theory on the Fuzzy Onion
Matej Hrmo, Samuel Kováčik, Juraj Tekel
We study the behaviour of the scalar field theory on the fuzzy onion model -- a three-dimensional matrix model consisting of concentric fuzzy spheres of gradually increasing radii.…

Eigenvalue-cluster Algorithm for Matrix Monte Carlo
Samuel KováÄik, Matej Hrmo
Various physical models can be expressed in terms of matrices. A valuable tool for analysing matrix models is numerical simulations, often the Metropolis algorithm with various imp…

Hydrogen Atom in a Fuzzy Spherical Cavity
Matej Hrmo, Samuel KováÄik, Patrik Rusnák +1
The fuzzy onion model formed by connecting a set of concentric fuzzy spheres of increasing radius is motivated by studies of quantum space but can also be used to study standard ph…
