Quantum particles at play: Game theory elucidates the collective behavior of bosons

(April 28, 2015)  Quantum particles behave in strange ways and are often difficult to study experimentally. Using mathematical methods drawn from game theory, LMU physicists have shown how bosons, which like to enter the same state, can form multiple groups.

When scientists explore the mysterious behavior of quantum particles, they soon reach the limits of present-day experimental research. From there on, progress is only possible with the aid of theoretical ideas. NIM investigator Prof. Erwin Frey and his team at the Dept. of Statistical and Biological Physics (LMU Munich) have followed this route to study the behavior of bosons. Bosons are quantum particles that like to cluster together. But by applying methods from the mathematical field of game theory, the Munich physicists were able to explain why and under what conditions bosons form multiple groups.
