A short note on Casimir force and radius stabilization in QFT with non-commutative target space

Michal Demetrian

Stable radius of cylindrical space due to additional repulsion caused by noncommutativity of two-component field values is found.

On computation of clustering coefficient in a class of random networks

Michal Demetrian, Martin Nehez

The random networks enriched with additional structures as metric and group-symmetry in background metric space are investigated. The important quantities like he clustering coeffi…

On Emergence of Dominating Cliques in Random Graphs

Martin Nehez, Daniel Olejar, Michal Demetrian

Emergence of dominating cliques in Erdös-Rényi random graph model ${\bbbg(n,p)}$ is investigated in this paper. It is shown this phenomenon possesses a phase transition. Namely, we…

Coleman - de Luccia instanton of the second order in a brane world

Michal Demetrian

The second order Coleman - de Luccia instanton and its action in the Randall - Sundrum type II model are investigated and the comparison with the results in Einstein's general rela…

False vacuum decay in a brane world cosmological model

Michal Demetrian

The false vacuum decay in a brane world model is studied in this work. We investigate the vacuum decay via the Coleman-de Luccia instanton, derive explicit approximative expression…

False vacuum decay with gravity in a critical case

Michal Demetrian

The vacuum decay in a de Sitter universe is studied within semiclassical approximation for the class of effective inflaton potentials whose curvature at the top is close to a criti…
