Aggregation in non-uniform systems with advection and localized source

Rishat R. Zagidullin, Alexander P. Smirnov, Sergey A. Matveev +2

We explore analytically and numerically agglomeration driven by advection and localized source. The system is inhomogeneous in one dimension, viz. along the direction of advection.…

Non-extensive super-cluster states in aggregation with fragmentation

Nikolai V. Brilliantov, Wendy Otieno, P. L. Krapivsky

Systems evolving through aggregation and fragmentation may possess an intriguing super-cluster state (SCS). Clusters constituting this state are mostly large, so the SCS resembles…

Monotonicity in the averaging process

E. Ben-Naim, P. L. Krapivsky

We investigate an averaging process that describes how interacting agents approach consensus through binary interactions. In each elementary step, two agents are selected at random…

Quasistatic work processes: When slowness implies certainty

Juyeon Yi, Peter Talkner

Two approaches are outlined to characterize the fluctuation behavior of work applied to a system by a slow change of a parameter. One approach uses the adiabatic theorems of quantu…

Fermi's golden rule for heating in strongly driven Floquet systems

Tatsuhiko N. Ikeda, Anatoli Polkovnikov

We study heating dynamics in isolated quantum many-body systems driven periodically at high frequency and large amplitude. Combining the high-frequency expansion for the Floquet Ha…

Divergence and Consensus in Majority Rule

P. L. Krapivsky, S. Redner

We investigate majority rule dynamics in a population with two classes of people, each with two opinion states , and with tunable interactions between people in different cl…

Blast in a One-Dimensional Cold Gas: From Newtonian Dynamics to Hydrodynamics

Subhadip Chakraborti, Santhosh Ganapa, P. L. Krapivsky +1

A gas composed of a large number of atoms evolving according to Newtonian dynamics is often described by continuum hydrodynamics. Proving this rigorously is an outstanding open pro…

Mean-field theory of an asset exchange model with economic growth and wealth distribution

W. Klein, N. Lubbers, Kang K. L. Liu +2

We develop a mean-field theory of the growth, exchange and distribution (GED) model introduced by Kang et al. (preceding paper) that accurately describes the phase transition in th…

Simulation of a generalized asset exchange model with economic growth and wealth distribution

Kang K. L. Liu, N. Lubbers, W. Klein +3

The agent-based Yard-Sale model of wealth inequality is generalized to incorporate exponential economic growth and its distribution. The distribution of economic growth is nonunifo…

Phase Amplification in Spinodal Decomposition of Immiscible Fluids with Interconversion of Species

Nikolay A. Shumovskyi, Thomas J. Longo, Sergey V. Buldyrev +1

A fluid composed of two molecular species may undergo phase segregation via spinodal decomposition. However, if the two molecular species can interconvert, e.g. change their chiral…
