Avalanche shape and exponents beyond mean-field theory
Alexander Dobrinevski, Pierre Le Doussal, Kay Jörg Wiese
Elastic systems, such as magnetic domain walls, density waves, contact lines, and cracks, are all pinned by substrate disorder. When driven, they move via successive jumps called a…
Mobility-Dependent Selection of Competing Strategy Associations
Alexander Dobrinevski, Mikko Alava, Tobias Reichenbach +1
Standard models of population dynamics focus on the the interaction, survival, and extinction of the competing species individually. Real ecological systems, however, are character…
Field theory of disordered systems -- Avalanches of an elastic interface in a random medium
Alexander Dobrinevski
In this thesis I discuss analytical approaches to disordered systems using field theory. Disordered systems are characterized by a random energy landscape due to heterogeneities, w…
Explore or exploit? A generic model and an exactly solvable case
Thomas Gueudré, Alexander Dobrinevski, Jean-Philippe Bouchaud
Finding a good compromise between the exploitation of known resources and the exploration of unknown, but potentially more profitable choices, is a general problem, which arises in…
Statistics of Avalanches with Relaxation, and Barkhausen Noise: A Solvable Model
Alexander Dobrinevski, Pierre Le Doussal, Kay Jörg Wiese
We study a generalization of the Alessandro-Beatrice-Bertotti-Montorsi (ABBM) model of a particle in a Brownian force landscape, including retardation effects. We show that under m…
Nonstationary dynamics of the Alessandro-Beatrice-Bertotti-Montorsi model
Alexander Dobrinevski, Pierre Le Doussal, Kay Jörg Wiese
We obtain an exact solution for the motion of a particle driven by a spring in a Brownian random-force landscape, the Alessandro-Beatrice-Bertotti-Montorsi (ABBM) model. Many exper…
