Percolation-like behavior of some optimal coalition formation models
Z. Neda, R. Florian, M. Ravasz +2
The ground-state of an infinite-range Potts glass-type model with +/- J bonds and unrestricted number of states is used to investigate coalition formation. As a function of the q p…

Improved percolation thresholds for rods in three-dimensional boxes
R. Florian, Z. Neda
We improve our previous results for the percolation thresholds of isotropically oriented rods in three dimensional boxes. We prove again the applicability of the excluded volume ru…

Limits of the Quantum Monte Carlo method
Z. Neda, Z. Dezso
We consider the one-dimensional quantum-statistical problem of interacting spin-less particles in an infinite deep potential valley and on a ring. Several limits for the applicabil…
