Hear $\pi$ from Quantum Galperin Billiards

Abstract

Galperin introduced an interesting method to learn the digits of π\pi by counting the collisions of two billiard balls and a hard wall. This paper studies two quantum versions of the Galperin billiards. It is shown that the digits of π\pi can be observed in the phase shifts of the quantum models.
