Rewriting quantum mechanics in their spare time

A pair of civil servants solve a quantum mechanics problem that had bothered them since they were students
The study took Jussi Lindgren, left, and Jukka Liukkonen, right, back to year 1941 when Stueckelberg鈥檚 wave equation was invented. The equation is the foundation for parameterized relativistic dynamics.
The study took Jussi Lindgren, left, and Jukka Liukkonen, right, back to year 1941 when Stueckelberg鈥檚 wave equation was invented. The equation is the foundation for parameterized relativistic dynamics.

As students, Jussi Lindgren and Jukka Liukkonen had found one element of their quantum mechanics lectures unsatisfying. 鈥淲hen 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,鈥 said Jussi Lindgren, 鈥渁nd I didn鈥檛 really like this鈥.

Working as a hobby alongside their jobs in the Finnish government, and Lindgren鈥檚 PhD 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 27 December 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. 鈥淭he method will be useful for teachers or learners because it gives a better understanding of the reason why something is correct,鈥 said Jukka Liukkonen.
