Coin Diffusion Study in Europe: Numerical Analysis of Country-to-Country Migration

Explore a numerical study on how coins move between European countries with travelers. Utilizing the Residence Time Algorithm, also known as BKL (Bortz, Kalos, Lebowitz), for a Kinetic Monte Carlo simulation. Analyze the time evolution of coin percentages, incorporating travel statistics from Eurostat data. Results showcase the impact of annual replenishment on Austrian, German, Italian, and French coins in various populations. Discover why 50% of coins are foreign and how physics methods apply to practical scenarios. Special thanks to Mikael Agopov and Summer Hotel Hill for support.

  1. EURO COIN DIFFUSION- a numerical study Tommi Bergman, Antti Lauri, Anna Ruhala and Walter Rydman Department of Physical Sciences University of Helsinki Finland

  2. THE METHOD • Basic idea: coins move from one country to another with travellers. • Residence time algorithm was used. • Also known as BKL (Bortz, Kalos, Lebowitz), kinetic Monte Carlo. Transitions selected randomly according to probabilities: P1 P2 P3 P4 P5 P6 • Travel statistics from • European Union data (Eurostat).

  3. RESULTS • Time evolution of the percentage of the Austrian coins in the domestic coin population. • Effect of 5% annual replenishment.

  4. RESULTS • Time evolution of the percentage of the German, Italian and French coins in the Greek total coin population.

  5. RESULTS: 50% FOREIGN

  6. WHY? • Diffusion is physics, isn’t it? • It is very important to show common public that physics methods can be used in ”real life” applications. • Out of curiosity .

  7. SPECIAL THANKS Mikael Agopov for providing computer facilities. Summer hotel Hill for the electricity and coffee machine…
