Description
Herzog, Thunström, and Eriksson published a 2025 paper on a faster way to solve a classic physics model of materials with strongly interacting electrons. The model treats one special atom embedded in a host material, and solving it is a heavy step inside a common theory of such materials. Their solver uses a method called configuration interaction and runs well even on a laptop, where older solvers often need large machines.
The team tested the solver on the metal cerium in three of its phases. As the metal was squeezed, its key electrons shifted from staying put on their atoms to roaming through the material. One middle phase stood apart, with electrons locked into a paired state. The paper also offers the solver as open-source software for other researchers.
