Topologies of Social Interactions

Ioannides, Yannis - Department of Economics, Tufts University - 2001

The paper adapts to richer social structures the Brock-Durlauf model of interactive discrete choice, where individuals’ decisions are influenced by the decisions of others. Social structure is modelled by a description of who interacts with whom, by means of a graph, with individuals as...

Critical properties of a spin-12 Ising superlattice in transverse fields

Kaneyoshi, T.; Shin, S. - In: Physica A: Statistical Mechanics and its Applications 284 (2000) 1, pp. 195-205

Critical properties (transition temperature and critical transverse field) of a spin-12 Ising superlattice in transverse fields consisting of alternating two different slabs with same thickness L are investigated by the use of the effective-field theory. When the transverse field and the...

Monte Carlo investigations of phase transitions: status and perspectives

Binder, Kurt; Luijten, Erik; Müller, Marcus; Wilding, … - In: Physica A: Statistical Mechanics and its Applications 281 (2000) 1, pp. 112-128

Using the concept of finite-size scaling, Monte Carlo calculations of various models have become a very useful tool for the study of critical phenomena, with the system linear dimension as a variable. As an example, several recent studies of Ising models are discussed, as well as the extension...
