Algebraic coarsening in voter models with intermediate states
Luca Dall'Asta, Tobias Galla
The introduction of intermediate states in the dynamics of the voter model modifies the ordering process and restores an effective surface tension. The logarithmic coarsening of th…
Statistical mechanics of combinatorial auctions
Tobias Galla, Michele Leone, Matteo Marsili +3
Combinatorial auctions are formulated as frustrated lattice gases on sparse random graphs, allowing the determination of the optimal revenue by methods of statistical physics. Tran…
Price return auto-correlation and predictability in agent-based models of financial markets
Damien Challet, Tobias Galla
We demonstrate that minority mechanisms arise in the dynamics of markets because of effects of price impact; accordingly the relative importance of minority and delayed majority me…
Defect formation in the Swift-Hohenberg equation
Tobias Galla, Esteban Moro
We study numerically and analytically the dynamics of defect formation during a finite-time quench of the two dimensional Swift-Hohenberg (SH) model of Rayleigh-Benard convection.…
