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…
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…
Microscopic black holes as probes for quantum gravity
Samuel Kováčik
One of the main goals of contemporary theoretical physics is to find the quantum theory of gravity. There are various working hypotheses, mostly operating in the regime of high-ene…
NC plane waves, Casimir effect and flux tube potential with Lüscher terms
Samuel Kováčik, Peter Prešnajder
We analyze plane waves in a model of quantum mechanics in a three dimensional noncommutative (NC) space . Signature features of NC models are impossibility of probing distan…
inspired black holes
Samuel Kováčik
We study a black hole with a blurred mass density instead of a singular one, which is caused by the noncommutativity of 3-space. Depending on its mass, such object has either none,…
