Becoming Large, Becoming Infinite: The Anatomy of Thermal Physics and Phase Transitions in Finite Systems
David A. Lavis, Reimer Kuehn, Roman Frigg
This paper presents an in-depth analysis of the anatomy of both thermodynamics and statistical mechanics, together with the relationships between their constituent parts. Based on…
Heterogeneity in Outcomes of Repeated Instances of Percolation Experiments
Reimer Kuehn, Jort van Mourik
We investigate the heterogeneity of outcomes of repeated instances of percolation experiments in complex networks using a message passing approach to evaluate heterogeneous, node d…
Second largest Eigenpair Statistics for Sparse Graphs
Vito A R Susca, Pierpaolo Vivo, Reimer Kühn
We develop a formalism to compute the statistics of the second largest eigenpair of weighted sparse graphs with nodes, finite mean connectivity and bounded maximal degree,…
Revealing the Micro-Structure of the Giant Component in Random Graph Ensembles
Ido Tishby, Ofer Biham, Eytan Katzav +1
The micro-structure of the giant component of the Erd{\H o}s-Rényi network and other configuration model networks is analyzed using generating function methods. While configuration…
Heterogeneous micro-structure of percolation in sparse networks
Reimer Kuehn, Tim Rogers
We examine the heterogeneous responses of individual nodes in sparse networks to the random removal of a fraction of edges. Using the message-passing formulation of percolation, we…
Large Deviations of the Finite-Time Magnetization of the Curie-Weiss Random Field Ising Model
Pierre Paga, Reimer Kühn
We study the large deviations of the magnetization at some finite time in the Curie-Weiss Random Field Ising Model with parallel updating. While relaxation dynamics in an infinite…
Kuehn and Mazzeo Reply
Reimer Kuehn, Giorgio Mazzeo
We reply to a comment of Van Enter, Kuelske and Maes (cond-mat/0005176) on our letter "Critical Behavior of the Randomly Spin-Diluted 2-d Ising Model - A Grand Ensemble Approach",…
Collective Phenomena in Defect Crystals
Reimer Kuehn, Alois Würger
We investigate effects of interactions between substitutional defects on the properties of defect crystals at low temperatures, where defect motion is governed by quantum effects.…
Translational Invariance in Models for Low-Temperature Properties of Glasses
Reimer Kuehn, Jens Urmann
We report on a refined version of our spin-glass type approach to the low-temperature physics of structural glasses. Its key idea is based on a Born von Karman expansion of the int…
Critical behaviour of the 2d spin diluted Ising model via the equilibrium ensemble approach
Giorgio Mazzeo, Reimer Kuehn
The equilibrium ensemble approach to disordered systems is used to investigate the critical behaviour of the two dimensional Ising model in presence of quenched random site dilutio…
A two step algorithm for learning from unspecific reinforcement
Reimer Kuehn, Ion-Olimpiu Stamatescu
We study a simple learning model based on the Hebb rule to cope with "delayed", unspecific reinforcement. In spite of the unspecific nature of the information-feedback, convergence…
A New Look at Low--Temperature Anomalies in Glasses
Reimer Kuehn, Uta Horstmann
We review a model--based rather than phenomenological approach to low--temperature anomalies in glasses. Specifically, we present a solvable model inspired by spin--glass theory th…
