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…
Eigenvalue distribution from bootstrap estimates
Samuel KováÄik, KatarÃna Magdolenová
The bootstrap method has proven useful for a wide range of matrix models. Here, we show that the computed momenta can be used to reconstruct the underlying eigenvalue probability d…
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…
The Fuzzy Onion: An Initial Study
Samuel KováÄik, Juraj Tekel, Matej Hrmo
In our previous contribution, we introduced a matrix formulation of a three-dimensional quantum space named the fuzzy onion. The novel part of the construction is the radial deriva…
