Static and Dynamic Anomalies in a Repulsive Spherical Ramp Liquid: Theory and Simulation
Pradeep Kumar, Sergey V. Buldyrev, Francesco Sciortino +2
We compare theoretical and simulation results for static and dynamic properties for a model of particles interacting via a spherically symmetric repulsive ramp potential. The model…
Understanding Search Trees via Statistical Physics
Satya N. Majumdar, David S. Dean, P. L. Krapivsky
We study the random m-ary search tree model (where m stands for the number of branches of a search tree), an important problem for data storage in computer science, using a variety…
First Passage Properties of the Erdos-Renyi Random Graph
V. Sood, S. Redner, D. ben-Avraham
We study the mean time for a random walk to traverse between two arbitrary sites of the Erdos-Renyi random graph. We develop an effective medium approximation that predicts that th…
Log-Networks
P. L. Krapivsky, S. Redner
We introduce a growing network model in which a new node attaches to a randomly-selected node, as well as to all ancestors of the target node. This mechanism produces a sparse, ult…
Levels of Complexity in Scale-Invariant Neural Signals
Plamen Ch. Ivanov, Jeffrey M. Hausdorff, S. Havlin +5
Many physical and physiological signals exhibit complex scale-invariant features characterized by scaling and long-range power-law correlations, suggesting a possibly common…
Stochastic series expansion algorithm for the S=1/2 XY model with four-site ring exchange
Roger G. Melko, Anders W. Sandvik
We describe a stochastic series expansion (SSE) quantum Monte Carlo method for a two-dimensional S=1/2 XY-model (or, equivalently, hard-core bosons at half-filling) which in additi…
Winning quick and dirty: the greedy random walk
E. Ben-Naim, S. Redner
As a strategy to complete games quickly, we investigate one-dimensional random walks where the step length increases deterministically upon each return to the origin. When the step…
Kinetic Theory of Random Graphs: from Paths to Cycles
E. Ben-Naim, P. L. Krapivsky
Structural properties of evolving random graphs are investigated. Treating linking as a dynamic aggregation process, rate equations for the distribution of node to node distances (…
Statistics of Weighted Networks
E. Almaas, P. L. Krapivsky, S. Redner
We study the statistics of growing networks in which each link carries a weight (k_i k_j)^theta, where k_i and k_j are the node degrees at the endpoints of link ij. Network growth…
Majority Rule Dynamics in Finite Dimensions
P. Chen, S. Redner
We investigate the long-time behavior of a majority rule opinion dynamics model in finite spatial dimensions. Each site of the system is endowed with a two-state spin variable that…
Optimization of Network Robustness to Waves of Targeted and Random Attack
T. Tanizawa, G. Paul, R. Cohen +2
We study the robustness of complex networks to multiple waves of simultaneous (i) targeted attacks in which the highest degree nodes are removed and (ii) random attacks (or failure…
Dynamical Critical Behaviors of the Ising Spin Chain: Swendsen-Wang and Wolff Algorithms
P. L. Krapivsky
We study the zero-temperature Ising chain evolving according to the Swendsen-Wang dynamics. We determine analytically the domain length distribution and various ``historical'' char…
Ultimate Fate of Constrained Voters
F. Vazquez, S. Redner
We determine the ultimate fate of individual opinions in a socially-interacting population of leftists, centrists, and rightists. In an elemental interaction between agents, a cent…
Theoretical Characterization of the Interface in a Nonequilibrium Lattice System
P. I. Hurtado, P. L. Garrido, J. Marro
The influence of nonequilibrium bulk conditions on the properties of the interfaces exhibited by a kinetic Ising--like model system with nonequilibrium steady states is studied. Th…
Common Scaling Patterns in Intertrade Times of U. S. Stocks
Plamen Ch. Ivanov, Ainslie Yuen, Boris Podobnik +1
We analyze the sequence of time intervals between consecutive stock trades of thirty companies representing eight sectors of the U. S. economy over a period of four years. For all…
Random Geometric Series
E. Ben-Naim, P. L. Krapivsky
Integer sequences where each element is determined by a previous randomly chosen element are investigated analytically. In particular, the random geometric series x_n=2x_p with 0<=…
Equilibrium statistical mechanics of network structures
I. Farkas, I. Derenyi, G. Palla +1
In this article we give an in depth overview of the recent advances in the field of equilibrium networks. After outlining this topic, we provide a novel way of defining equilibrium…
Out-of-equilibrium dynamical fluctuations in glassy systems
C. Chamon, P. Charbonneau, L. F. Cugliandolo +2
In this paper we extend the earlier treatment of out-of-equilibrium mesoscopic fluctuations in glassy systems in several significant ways. First, via extensive simulations, we demo…
Reentrant Behavior of the Spinodal Curve in a Nonequilibrium Ferromagnet
P. I. Hurtado, J. Marro, P. L. Garrido
The metastable behavior of a kinetic Ising--like ferromagnetic model system in which a generic type of microscopic disorder induces nonequilibrium steady states is studied by compu…
