Eigenvalue distribution from bootstrap estimates
Samuel Kováčik, Katarína 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 Kováčik, 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…

Fuzzy Onion as a Matrix Model
Samuel Kováčik, Juraj Tekel
We propose a matrix model realisation of a three-dimensional quantum space. It has an onion-like structure composed of concentric fuzzy spheres of increasing radius. The angular pa…
