Eigenvalue-flipping Algorithm for Matrix Monte Carlo
Samuel Kováčik, Juraj Tekel
Many physical systems can be described in terms of matrix models that we often cannot solve analytically. Fortunately, they can be studied numerically in a straightforward way. Man…
Hawking-Radiation Recoil of Microscopic Black Holes
Samuel Kováčik
Hawking radiation would make microscopic black holes evaporate rapidly, which excludes them from many astrophysical considerations. However, it has been argued that the quantum nat…
The Confining Transition in the Bosonic BMN Matrix Model
Yuhma Asano, Samuel Kováčik, Denjoe O'Connor
We study the confining/deconfining phase transition in the mass deformed Yang-Mills matrix model which is obtained by the dimensional reduction of the bosonic sector of the four-di…
Triple Point of a Scalar Field Theory on a Fuzzy Sphere
Samuel Kováčik, Denjoe O'Connor
The model of a scalar field with quartic self-interaction on the fuzzy sphere has three known phases: a uniformly ordered phase, a disordered phase and a non-uniformly ordered phas…
The non-perturbative phase diagram of the BMN matrix model
Yuhma Asano, Veselin G. Filev, Samuel Kováčik +1
We study the maximally supersymmetric plane wave matrix model (the BMN model) at finite temperature, , and locate the high temperature phase boundary in the plane, where…
Magnetic Monopoles in (Noncommutative) Quantum Mechanics
Samuel Kováčik, Peter Prešnajder
We utilize the close relation between the complex space and the real space to reformulate quantum mechanics in a manner which allows to, either or bot…
