Method for estimating critical exponents in percolation processes with low sampling
Nikolaos Bastas, Kosmas Kosmidis, Paraskevas Giazitzidis +1
In phase transition phenomena, the estimation of the critical point is crucial for the calculation of the various critical exponents and the determination of the universality class…
Variation of the critical percolation threshold in the Achlioptas processes
Paraskevas Giazitzidis, Isak Avramov, Panos Argyrakis
We investigate variations of the well-known Achlioptas percolation problem, which uses the method of probing sites when building up a lattice system, or probing links when building…
Explosive Percolation: Unusual Transitions of a Simple Model
Nikolaos Bastas, Paraskevas Giazitzidis, Michael Maragakis +1
In this paper we review the recent advances on explosive percolation, a very sharp phase transition first observed by Achlioptas et al. (Science, 2009). There a simple model was pr…
Charge separation in organic photovoltaic cells
Paraskevas Giazitzidis, Panos Argyrakis, Juan Bisquert +1
We consider a simple model for the geminate electron-hole separation process in organic photovoltaic cells, in order to illustrate the influence of dimensionality of conducting cha…
Generalized Achlioptas process for the delay of criticality in the percolation process
Paraskevas Giazitzidis, Panos Argyrakis
We extend the Achlioptas model for the delay of criticality in the percolation problem. Instead of having a completely random connectivity pattern, we generalize the idea of the tw…
