Random matrix models for phase diagrams
Benoit Vanderheyden, A D Jackson
We describe a random matrix approach that can provide generic and readily soluble mean-field descriptions of the phase diagram for a variety of systems ranging from QCD to high-T_c…
Anomalous Multiplicity Fluctuations from Phase Transitions in Heavy Ion Collisions
H. Heiselberg, A. D. Jackson
Event-by-event fluctuations and correlations between particles produced in relativistic nuclear collisions are studied. The fluctuations in positive, negative, total and net charge…
Partitioning Composite Finite Systems
A. S. Botvina, A. D. Jackson, I. N. Mishustin
We compare different analytical and numerical methods for studying the partitions of a finite system into fragments. We propose a new numerical method of exploring the partition sp…
Criticality in Simple Models of Evolution
Jan de Boer, A. D. Jackson, Tilo Wettig
We consider two, apparently similar, models of biological evolution which have been claimed to exhibit self-organized critical behaviour. A careful reanalysis of these models, incl…
Factorial Moments in a Generalized Lattice Gas Model
T. Wettig, A. D. Jackson
We construct a simple multicomponent lattice gas model in one dimension in which each site can either be empty or occupied by at most one particle of any one of species. Partic…
