Coarse-Graining via Lumping: Exact Calculations and Fundamental Limitations
Gianluca Teza, Attilio L. Stella, Trevor GrandPre
Detecting broken time-reversibility at micro- and nanoscale is often difficult when experiments offer limited state resolution. We introduce a lumping method that builds an effecti…
Universal and non-universal signatures in the scaling functions of critical variables
Gianluca Teza, Attilio L. Stella
The view that the probability density function (PDF) of a key statistical variable, anomalously scaled by size or time, could furnish a hallmark of universal behavior contrasts wit…
Topological signatures of globular polymers
M. Baiesi, E. Orlandini, A. L. Stella +1
Simulations in which a globular ring polymer with delocalized knots is separated in two interacting loops by a slipping link, or in two non-interacting globuli by a wall with a hol…
Scaling and efficiency determine the irreversible evolution of a market
Fulvio Baldovin, Attilio L. Stella
In setting up a stochastic description of the time evolution of a financial index, the challenge consists in devising a model compatible with all stylized facts emerging from the a…
Role of scaling in the statistical modeling of finance
Attilio L. Stella, Fulvio Baldovin
Modeling the evolution of a financial index as a stochastic process is a problem awaiting a full, satisfactory solution since it was first formulated by Bachelier in 1900. Here it…
A scale-free network hidden in the collapsing polymer
A. Kabakcioglu, A. L. Stella
We show that the collapsed globular phase of a polymer accommodates a scale-free incompatibility graph of its contacts. The degree distribution of this network is found to decay wi…
