I thought we already knew this. Euler's Identity is used in electrical engineering.

  Yes but they are claiming that the link between the real and imaginary parts of the solutions to the Schrodinger Equation are "more linked" than just by the hamiltonian. Have looked over the introduction of the preprint and have some issues with it but am not an expert.

  That can be reformulated using only real numbers, similar to some math the article mentions for quantum mechanics: > Any property of complex numbers can be captured by combinations of real numbers plus new rules to keep them in line, opening up the mathematical possibility of an all-real version of quantum mechanics.

  But that is only for convenience. You can do everything with real trigonometry, just that it’s a bit more cumbersome. The imaginary numbers don’t correspond to anything in physical reality in electrical engineering.
