Pair of Civil Servants Rewrite Quantum Mechanics in Their Spare Time

A pair of civil servants solve a quantum mechanics problem that had bothered them since they were students.

As students, Jussi Lindgren and Jukka Liukkonen had found one element of their quantum mechanics lectures unsatisfying. “When we were taught physics, there were some fundamental elements you were told were true, and you had to accept they were true without it being shown why,” said Jussi Lindgren, “and I didn’t really like this.”

Working as a hobby alongside their jobs in the Finnish government, and Lindgren’s Ph.D. work in systems analysis at Aalto, the researchers devised a new method for expressing the laws of quantum mechanics using stochastic methods, a type of mathematics that deals with random chance and probability.

The paper, published December 27, 2019, in Scientific Reports explores how stochastic methods can be used to derive a variety of equations in quantum mechanics from first principles, as opposed to having to build from ad hoc prior postulates. “The method will be useful for teachers or learners because it gives a better understanding of the reason why something is correct,” said Jukka Liukkonen.
