Central Forces and Two-Particle Systems

AbstractWe study the symmetric inclusion process (SIP) in the condensation regime. We obtain an explicit scaling for the variance of the density field in this regime, when initially started from a homogeneous product measure. This provides relevant new information on the coarsening dynamics of condensing interacting particle systems on the infinite lattice. We obtain our result by proving convergence to sticky Brownian motion for the difference of positions of two SIP particles in the sense of Mosco convergence of Dirichlet forms. Our approach implies the convergence of the probabilities of two SIP particles to be together at time t. This, combined with self-duality, allows us to obtain the explicit scaling for the variance of the fluctuation field.

Central Forces

This article analyzes three video-recorded asylum interviews, their written records and the corresponding decisions by the Finnish Immigration Service. The goal is to identify the causes and consequences of vulnerability in instances that are particularly important when assessing whether the asylum seeker has a well-grounded fear of persecution. A combination of linguistic, psychological and epistemic perspectives on vulnerability shows that these three dimensions are closely intertwined in asylum interviews. Linguistic vulnerability is linked for the most part to interpreting, whereas psychological vulnerability stems from the difficulty in recounting traumatic experiences. Both linguistic and psychological vulnerabilities are central forces that also lead to epistemic vulnerability. Epistemic vulnerability, we claim, gives rise to certain practices within the asylum procedure, which again represents the materialization of the discourses of reporting, truth and credibility.
