Nonlinear Physics seminar: "Optimization and Wealth Sharing in First-Passage Resetting"
- Start time: 12:00pm
- End date: Wednesday, October 30th
- End time: 01:30pm
- Lecturer: Prof. Sid Redner, Santa Fe Institute Abstract:We investigate classic diffusion with the added feature that a diffusingparticle is reset to its starting point each time the particle reaches aspecified threshold. In an infinite domain, first-passage resetting isnon-stationary and its probability distribution exhibits rich features.In a finite domain, first-passage resetting leads to a nontrivialoptimization in which a cost is incurred whenever the particle is resetand a reward is given when the particle stays near the reset (maximalperformance) point. We derive the condition to optimize the net gain(reward-cost). We also explore simple consequences of first-passageresetting in a toy model of wealth sharing.
