Accretion, mergers, and metastability of fuzzy spheres in a three-matrix model
M. Hrmo, S. Kováčik, K. Magdolenová +5
A three-matrix model that contains a plethora of fuzzy sphere solutions was defined twenty years ago. It has been shown that in a certain regime of the model, combinations of fuzzy…

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 Kováčik, 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…
