Human wealth evolution is an accelerating expansion underpinned by a decelerating optimization process
Paolo Sibani, Steen Rasmussen, Per Lyngs Hansen
Optimization and expansion are two modes of staged evolution of complex systems where macroscopic observables change at a decreasing, respectively increasing, rate. A prime example…
Extremal fluctuations driving the relaxation in glassy energy landscapes
Stefan Boettcher, Paula A. Gago, Paolo Sibani
Cooperative events requiring anomalously large fluctuations are a defining characteristic for the onset of glassy relaxation across many materials. The importance of such intermitt…
Record dynamics of evolving metastable systems: theory and applications
Paolo Sibani, Stefan Boettcher, Henrik Jeldtoft Jensen
Record Dynamics (RD) deals with complex systems evolving through a sequence of metastable stages. These are macroscopically distinguishable and appear stationary, except for the su…
Spin-glass thermo-remanent magnetization revisited: a numerical and analytical study
Paolo Sibani, Jacob Møller Kirketerp
Thermoremanent magnetization data for the 3D Edwards-Anderson spin glass are generated using the Waiting Time Method as simulational tool and interpreted using Record Dynamics. We…
Human wealth evolution: trends and fluctuations
Paolo Sibani, Steen Rasmussen
Is a causal description of human wealth history conceivable? To investigate the matter we introduce a simple causal albeit strongly aggregated model, assuming that the observed wea…
Dynamics of dense hard sphere colloidal systems: a numerical analysis
Paolo Sibani, Carsten Svaneborg
The applicability to dense hard sphere colloidal suspensions of a general coarse-graining approach called Record Dynamics (RD) is tested by extensive molecular dynamics simulations…
