Finite Size Fluctuations in Interacting Particle Systems

E. Ben-Naim, P. L. Krapivsky

Fluctuations may govern the fate of an interacting particle system even on the mean-field level. This is demonstrated via a three species cyclic trapping reaction with a large, yet…

Universal adiabatic dynamics across a quantum critical point

Anatoli Polkovnikov

We study temporal behavior of a quantum system under a slow external perturbation, which drives the system across a second order quantum phase transition. It is shown that despite…

Spatial Growth of Real-world Networks

Marcus Kaiser, Claus C. Hilgetag

Many real-world networks have properties of small-world networks, with clustered local neighborhoods and low average-shortest path (ASP). They may also show a scale-free degree dis…

Aging in short-ranged attractive colloids: A numerical study

G. Foffi, E. Zaccarelli, S. Buldyrev +2

We study the aging dynamics in a model for dense simple liquids, in which particles interact through a hard-core repulsion complemented by a short-ranged attractive potential, of t…

Extremal Properties of Random Structures

E. Ben-Naim, P. L. Krapivsky, S. Redner

The extremal characteristics of random structures, including trees, graphs, and networks, are discussed. A statistical physics approach is employed in which extremal properties are…

Dynamical obstruction in a constrained system and its realization in lattices of superconducting devices

C. Castelnovo, P. Pujol, C. Chamon

Hard constraints imposed in statistical mechanics models can lead to interesting thermodynamical behaviors, but may at the same time raise obstructions in the thoroughfare to therm…

Dynamics of an Unbounded Interface Between Ordered Phases

P. L. Krapivsky, S. Redner, J. Tailleur

We investigate the evolution of a single unbounded interface between ordered phases in two-dimensional Ising ferromagnets that are endowed with single-spin-flip zero-temperature Gl…

Potential energy landscape-based extended van der Waals equation

T. Keyes, J. Chowdhary

The inherent structures ({\it IS}) are the local minima of the potential energy surface or landscape, , of an {\it N} atom system. Stillinger has given an exact {\it IS…

Heuristic Segmentation of a Nonstationary Time Series

Kensuke Fukuda, H. Eugene Stanley, Luis A. Nunes Amaral

Many phenomena, both natural and human-influenced, give rise to signals whose statistical properties change under time translation, i.e., are nonstationary. For some practical purp…

Scale-Dependent Price Fluctuations for the Indian Stock Market

Kaushik Matia, Mukul Pal, H. Eugene Stanley +1

Classic studies of the probability density of price fluctuations for stocks and foreign exchanges of several highly developed economies have been interpreted using a {\it power…

Multifractal Properties of Price Fluctuations of Stocks and Commodities

Kaushik Matia, Yosef Ashkenazy, H. Eugene Stanley

We analyze daily prices of 29 commodities and 2449 stocks, each over a period of years. We find that the price fluctuations for commodities have a significantly broade…

Leadership Statistics in Random Structures

E. Ben-Naim, P. L. Krapivsky

The largest component (``the leader'') in evolving random structures often exhibits universal statistical properties. This phenomenon is demonstrated analytically for two ubiquitou…

Majority versus minority dynamics: Phase transition in an interacting two-state spin system

M. Mobilia, S. Redner

We introduce a simple model of opinion dynamics in which binary-state agents evolve due to the influence of agents in a local neighborhood. In a single update step, a fixed-size gr…

Competition between homogeneous and local processes in a diffusive many-body system

Mauro Mobilia

We consider a stochastic many-body system where a source refills uniformly the empty sites of a hypercubic lattice, on which each particle is allowed to jump (symmetrically) onto n…

Exchange Driven Growth

E. Ben-Naim, P. L. Krapivsky

We study a class of growth processes in which clusters evolve via exchange of particles. We show that depending on the rate of exchange there are three possibilities: I) Growth: Cl…

Does a Single Zealot Affect an Infinite Group of Voters ?

Mauro Mobilia

A method for studying exact properties of a class of {\it inhomogeneous} stochastic many-body systems is developed and presented in the framework of a voter model perturbed by the…

Dynamics of Majority Rule

P. L. Krapivsky, S. Redner

We introduce a 2-state opinion dynamics model where agents evolve by majority rule. In each update, a group of agents is specified whose members then all adopt the local majority s…

Shattering Transitions in Collision-Induced Fragmentation

P. L. Krapivsky, E. Ben-Naim

We investigate the kinetics of nonlinear collision-induced fragmentation. We obtain the fragment mass distribution analytically by utilizing its travelling wave behavior. The syste…

Kinetic Anomalies in Addition-Aggregation Processes

M. Mobilia, P. L. Krapivsky, S. Redner

We investigate irreversible aggregation in which monomer-monomer, monomer-cluster, and cluster-cluster reactions occur with constant but distinct rates K_{MM}, K_{MC}, and K_{CC},…

The Inelastic Maxwell Model

E. Ben-Naim, P. L. Krapivsky

Dynamics of inelastic gases are studied within the framework of random collision processes. The corresponding Boltzmann equation with uniform collision rates is solved analytically…
